Switch devices 3 are provided on the 2 o'clock side, the 3 o'clock side, the 4 o'clock side, the 8 o'clock side, and the 10 o'clock side of the wristwatch case 1 .

この場合、腕時計ケース１は、図２に示すように、本体ケース４とベゼルケース５とを備えている。本体ケース４は、ステンレスなどの金属または硬質の合成樹脂によって形成されている。ベゼルケース５は、本体ケース４の外周を覆うものであり、ウレタン樹脂などの軟質の合成樹脂によって形成されている。 In this case, the wristwatch case 1 includes a body case 4 and a bezel case 5, as shown in FIG. The body case 4 is made of metal such as stainless steel or hard synthetic resin. The bezel case 5 covers the outer periphery of the main body case 4 and is made of soft synthetic resin such as urethane resin.

また、腕時計ケース１の上側開口部、つまり本体ケース４の上側開口部には、図２に示すように、時計ガラス６がガラスパッキン６ａを介して取り付けられている。この腕時計ケース１の下部、つまり本体ケース４の下部には、裏蓋７が蓋パッキン７ａを介して取り付けられている。 A watch glass 6 is attached to the upper opening of the wristwatch case 1, that is, the upper opening of the main body case 4, via a glass packing 6a, as shown in FIG. A back cover 7 is attached to the lower part of the wristwatch case 1, that is, to the lower part of the main body case 4 via a cover packing 7a.

この腕時計ケース１の内部、つまり本体ケース４の内部には、図２に示すように、時計モジュール１０が収納されている。この時計モジュール１０は、図示しないが、指針を運針させて時刻を指示させる時計ムーブメント、時刻などの情報を電気光学的に表示する平面型の表示パネル、これらを駆動して制御する回路基板などの時計機能に必要な各種の部品を備えている。 Inside the wristwatch case 1, that is, inside the body case 4, a timepiece module 10 is accommodated as shown in FIG. Although not shown, the clock module 10 includes a clock movement that moves hands to indicate the time, a flat display panel that electro-optically displays information such as the time, and a circuit board that drives and controls them. Equipped with various parts necessary for clock functions.

ところで、腕時計ケース１の複数のスイッチ装置３のうち、例えば２時側のスイッチ装置３は、図２に示すように、腕時計ケース１の本体ケース４に設けられた貫通孔１１に取り付けられる操作部材１２と、本体ケース４の外面と操作部材１２の後述する頭部１６との間に配置されるばね性を有する緩衝体１３と、を備えている。 By the way, among the plurality of switch devices 3 of the wristwatch case 1, for example, the switch device 3 on the 2 o'clock side is an operation member attached to a through hole 11 provided in the body case 4 of the wristwatch case 1, as shown in FIG. 12, and a shock absorbing body 13 having a spring property disposed between the outer surface of the main body case 4 and a head portion 16 of the operating member 12, which will be described later.

この場合、本体ケース４には、図２に示すように、緩衝体１３が配置される収納凹部１４が貫通孔１１に対応して設けられている。この収納凹部１４は、本体ケース４の円周方向に長いほぼ長形状に形成され、その長手方向と直交する短手方向の長さが貫通孔１１の内径よりも大きく、かつ操作部材１２の後述する頭部１６の外径よりも小さい大きさで形成されている。 In this case, as shown in FIG. 2 , housing recesses 14 in which buffers 13 are arranged are provided in main body case 4 so as to correspond to through holes 11 . The storage recess 14 is formed in a substantially elongated shape elongated in the circumferential direction of the main body case 4, the length in the short side direction perpendicular to the longitudinal direction is longer than the inner diameter of the through hole 11, and the operation member 12 is larger than the operation member 12, which will be described later. It is formed in a size smaller than the outer diameter of the head 16 to be connected.

操作部材１２は、図２に示すように、本体ケース４の貫通孔１１にスライド可能に挿入される軸部１５と、この軸部１５の外端部に設けられて本体ケース４の外部に配置される頭部１６と、を備えている。軸部１５は、外径が本体ケース４の貫通孔１１の内径とほぼ同じ大きさで、軸方向の長さが本体ケース４の肉厚、つまり貫通孔１１と収納凹部１４との両方の軸方向における長さよりも長く形成されている。 As shown in FIG. 2 , the operation member 12 includes a shaft portion 15 that is slidably inserted into the through hole 11 of the main body case 4 , and an outer end portion of the shaft portion 15 that is provided outside the main body case 4 . and a head 16 which is mounted on the head. The shaft portion 15 has an outer diameter approximately equal to the inner diameter of the through hole 11 of the main body case 4 , and an axial length equal to the wall thickness of the main body case 4 , that is, the axis of both the through hole 11 and the storage recess 14 . It is formed longer than the length in the direction.

これにより、軸部１５は、図２に示すように、本体ケース４の貫通孔１１に挿入された際に、内端部が本体ケース４内に突出し、外端部が収納凹部１４から本体ケース４の外部に突出するように構成されている。この場合、軸部１５は、本体ケース４内に突出した内端部にＥリングなどの抜止め部材１７が取り付けられている。この抜止め部材１７は、本体ケース４の内周面に接離可能に当接することにより、軸部１５が本体ケース４から外部に抜け出さないように構成されている。 Thus, as shown in FIG. 2, when the shaft portion 15 is inserted into the through hole 11 of the main body case 4, the inner end portion of the shaft portion 15 protrudes into the main body case 4, and the outer end portion of the shaft portion 15 protrudes from the housing recess 14 into the main body case. 4 is configured to protrude to the outside. In this case, the shaft portion 15 has a retaining member 17 such as an E-ring attached to the inner end portion protruding into the main body case 4 . The retaining member 17 is configured to contact the inner peripheral surface of the main body case 4 so as to be able to contact and separate therefrom, thereby preventing the shaft portion 15 from slipping out of the main body case 4 .

また、この軸部１５は、図２に示すように、本体ケース４の貫通孔１１に挿入された箇所の外周面に複数の防水リング１８が設けられ、これら複数の防水リング１８が貫通孔１１の内周面に圧接した状態で摺動するように構成されている。これにより、軸部１５は、貫通孔１１内でスライドしても、複数の防水リング１８によって貫通孔１１の内周面と軸部１５の外周面との間の防水を図るように構成されている。 As shown in FIG. 2, the shaft portion 15 is provided with a plurality of waterproof rings 18 on the outer peripheral surface of the portion inserted into the through hole 11 of the main body case 4 . It is configured to slide while being pressed against the inner peripheral surface of the. As a result, even if the shaft portion 15 slides within the through hole 11 , the plurality of waterproof rings 18 provide waterproofing between the inner peripheral surface of the through hole 11 and the outer peripheral surface of the shaft portion 15 . there is

操作部材１２の頭部１６は、図２に示すように、ほぼ円柱状に形成され、その内端面に軸部１５の外端部が一体に設けられた構造になっている。この頭部１６は、外径が本体ケース４の収納凹部１４における短手方向の長さよりも少し大きく形成されている。また、この頭部１６は、軸方向の長さが本体ケース４の貫通孔１１の軸方向の長さとほぼ同じ長さで、収納凹部１４の軸方向の長さよりも少し長く、かつベゼルケース５の外周部の肉厚よりも長く形成されている。 As shown in FIG. 2, the head portion 16 of the operating member 12 is formed in a substantially cylindrical shape, and has a structure in which the outer end portion of the shaft portion 15 is integrally provided on the inner end surface thereof. The head 16 is formed to have an outer diameter slightly larger than the width of the storage recess 14 of the main body case 4 in the lateral direction. The axial length of the head 16 is substantially the same as the axial length of the through hole 11 of the main body case 4 and is slightly longer than the axial length of the storage recess 14 , and the bezel case 5 It is formed longer than the thickness of the outer peripheral portion of the.

これにより、頭部１６は、図２に示すように、本体ケース４の外部に配置された状態で、外端部がベゼルケース５の外部に突出して配置されている。このため、頭部１６は、ベゼルケース５の外部からスイッチ操作が容易にかつ良好に行えるように構成されている。この場合、本体ケース４内の時計モジュール１０は、操作部材１２の頭部１６が押圧されて、軸部１５の内端部が本体ケース４内に押し込まれた際に、軸部１５の内端部によってスイッチ動作するスイッチ部１９を備えている。 As a result, the head portion 16 is disposed outside the main body case 4 , and the outer end of the head portion 16 protrudes outside the bezel case 5 as shown in FIG. 2 . Therefore, the head 16 is configured so that the switch can be easily and satisfactorily operated from the outside of the bezel case 5 . In this case, the timepiece module 10 in the body case 4 is pushed by the head 16 of the operation member 12 and the inner end of the shaft 15 is pushed into the body case 4 . A switch section 19 is provided for switching operation by the section.

このスイッチ部１９は、図２に示すように、スイッチ本体１９ａと、このスイッチ本体１９ａに接離可能に押し当てられる板ばね状の接点板１９ｂと、を備えている。これにより、スイッチ部１９は、接点板１９ｂが軸部１５の内端部によって押されてスイッチ本体１９ａに押し当てられることにより、オン動作し、軸部１５の内端部が本体ケース４の外部に向けてスライドした際に、接点板１９ｂがスイッチ本体１９ａから離れてオフ状態になるように構成されている。 As shown in FIG. 2, the switch unit 19 includes a switch body 19a and a contact plate 19b in the form of a leaf spring which is pressed against the switch body 19a so as to be able to contact and separate therefrom. As a result, the contact plate 19b is pressed against the switch body 19a by the inner end portion of the shaft portion 15, and the switch portion 19 is turned on. , the contact plate 19b is separated from the switch body 19a to be turned off.

ところで、緩衝体１３は、図２～図４に示すように、ダイラタンシー特性を有するゲル状の素材２０を弾性材２１で包んだものであり、ばね性を備え、本体ケース４の収納凹部１４内に配置されている。この場合、緩衝体１３は、ゲル状の素材２０のダイラタンシー特性を発揮させるため、操作部材１２の頭部１６よりもサイズが大きく形成されている。 By the way, as shown in FIGS. 2 to 4, the cushioning body 13 is made by wrapping a gel-like material 20 having a dilatancy characteristic with an elastic material 21, and has a spring property. are placed in In this case, the cushioning body 13 is formed larger in size than the head portion 16 of the operating member 12 in order to exhibit the dilatancy characteristics of the gel-like material 20 .

このため、本体ケース４の収納凹部１４も、図２に示すように、その長手方向の長さが頭部１６の外径よりも大きく形成されている。また、この緩衝体１３は、軸部１５の軸方向の長さ（厚み）が収納凹部１４の軸方向の長さ（深さ）よりも長く形成されている、これにより、緩衝体１３は、収納凹部１４内に配置された際に、収納凹部１４から本体ケース４の外部側に突出する構造になっている。 For this reason, as shown in FIG. 2, the housing recess 14 of the main body case 4 is also formed to have a longitudinal length greater than the outer diameter of the head 16 . In addition, the buffer 13 is formed such that the axial length (thickness) of the shaft portion 15 is longer than the axial length (depth) of the storage recess 14. As a result, the buffer 13 is It has a structure in which it protrudes from the storage recess 14 to the outside of the main body case 4 when it is arranged in the storage recess 14 .

ダイラタンシー特性を有するゲル状の素材２０は、図２および図４（ｂ）に示すように、操作部材１２が弾性材２１を弾性変形させる程度の押圧力でスイッチ部１９をスイッチ操作させる際に弾性的に変形し、衝撃などの強い力が加わった際に変形せずに硬くなるものである。すなわち、このゲル状の素材２０は、低衝撃つまり低い周波数の衝撃に対して低反発で液体のように弾力的にゆっくり変形し、高衝撃つまり高い周波数の衝撃に対して高反発で弾力が低下してあまり変形せずに固体のように硬くなるものである。 As shown in FIGS. 2 and 4B, the gel-like material 20 having the dilatancy property is elastic when the switch portion 19 is operated by the operating member 12 with a pressing force that causes the elastic member 21 to elastically deform. It deforms at random, and when a strong force such as an impact is applied, it hardens without deforming. That is, the gel-like material 20 deforms slowly and elastically like a liquid with low rebound against low impact, that is, low frequency impact, and has high rebound against high impact, that is, high frequency impact, and its elasticity decreases. It becomes hard like a solid without much deformation.

このため、このゲル状の素材２０は、図２および図４（ｂ）に示すように、低衝撃つまり操作部材１２がスイッチ部１９をスイッチ操作させる程度の押圧力で押圧された際に弾性的に変形する変形量が、操作部材１２の操作ストロークＳ１とスイッチ部１９の動作ストロークＳ２との差の長さ（Ｓ１－Ｓ２）の範囲内に設定されている。 Therefore, as shown in FIGS. 2 and 4(b), the gel-like material 20 is elastic when the operating member 12 is pressed with a pressing force that causes the switch portion 19 to switch. is set within the range of the difference between the operation stroke S1 of the operation member 12 and the operation stroke S2 of the switch portion 19 (S1-S2).

一方、弾性材２１は、図２～図４に示すように、ゲル状の素材２０を包み込む外周皮膜で、シリコーンゴム、ウレタンゴム、エラストマーなどの弾力を備えた材料であり、好ましくはシリコーンゴムである。この弾性材２１は、操作部材１２の操作ストロークＳ１の範囲内で弾性変形することにより、ばね部材としての機能を有する構造になっている。すなわち、この弾性材２１は、操作部材１２の頭部１６によって押圧されて弾性変形し、その弾性変形の復元力によって操作部材１２を元の状態に復帰させるように構成されている。 On the other hand, as shown in FIGS. 2 to 4, the elastic material 21 is a peripheral film that wraps around the gel-like material 20, and is made of an elastic material such as silicone rubber, urethane rubber, or elastomer, preferably silicone rubber. be. The elastic member 21 has a structure that functions as a spring member by elastically deforming within the range of the operation stroke S1 of the operation member 12 . That is, the elastic member 21 is elastically deformed when pressed by the head portion 16 of the operating member 12, and the restoring force of the elastic deformation returns the operating member 12 to its original state.

また、この弾性材２１は、図２～図４に示すように、緩衝体１３の外形と同じ大きさの長方形の箱状に形成され、その内部にゲル状の素材２０を封入する構造になっている。この場合、弾性材２１は、内部における中心部に軸部１５が挿入する円筒部２１ａが設けられた構造になっている。この円筒部２１ａは、内径が軸部１５の外径よりも大きく形成されている。 As shown in FIGS. 2 to 4, the elastic member 21 is formed in the shape of a rectangular box having the same size as the outer shape of the cushioning body 13, and has a structure in which the gel-like material 20 is enclosed inside. ing. In this case, the elastic member 21 has a structure in which a cylindrical portion 21a into which the shaft portion 15 is inserted is provided in the central portion thereof. The cylindrical portion 21 a has an inner diameter larger than the outer diameter of the shaft portion 15 .

この弾性材２１は、図２～図４に示すように、操作部材１２の軸部１５のスライド方向と平行な側壁である第１外壁部２１ｂと、軸部１５のスライド方向と直交する一対の平板である第２外壁部２１ｃと、を備えている。この第１外壁部２１ｂは、その肉厚が第２外壁部２１ｃの肉厚よりも厚く形成されている。この場合、一対の平板状の第２外壁部２１ｃのうち、操作部材１２の頭部１６側に位置する第２外壁部２１ｃは、収納凹部１４の底部側に位置する第２外壁部２１ｃよりも肉厚が薄く形成されている。 2 to 4, the elastic member 21 includes a first outer wall portion 21b, which is a side wall parallel to the sliding direction of the shaft portion 15 of the operating member 12, and a pair of outer wall portions perpendicular to the sliding direction of the shaft portion 15. and a second outer wall portion 21c that is a flat plate. The first outer wall portion 21b is formed to be thicker than the second outer wall portion 21c. In this case, of the pair of flat plate-shaped second outer wall portions 21 c , the second outer wall portion 21 c positioned closer to the head portion 16 of the operation member 12 is positioned closer to the bottom side of the recessed storage portion 14 than the second outer wall portion 21 c positioned closer to the bottom portion of the storage recess 14 . The thickness is formed thin.

また、弾性材２１の円筒部２１ａは、図２～図４に示すように、その肉厚が第１外壁部２１ｂの肉厚とほぼ同じ厚さで形成されている。また、弾性材２１の円筒部２１ａと第１外壁部２１ｂとは、緩衝体１３が操作部材１２の頭部１６で押された際の変形量が、ダイラタンシー特性を有するゲル状の素材２０の変形量よりも大きく設定されている。 Further, as shown in FIGS. 2 to 4, the cylindrical portion 21a of the elastic member 21 is formed to have substantially the same thickness as the first outer wall portion 21b. The cylindrical portion 21a and the first outer wall portion 21b of the elastic member 21 are deformed by the gel-like material 20 having dilatancy characteristics when the buffer 13 is pushed by the head portion 16 of the operation member 12. It is set larger than the amount.

これにより、緩衝体１３は、図２～図４に示すように、操作部材１２の頭部１６によって押圧されて弾性材２１の第１外壁部２１ｂと円筒部２１ａとが弾性変形すると共に、ゲル状の素材２０が液体のように弾性的に変形した際に、円筒部２１ａおよび第１外壁部２１ｂとゲル状の素材２０との両方の変形量によって、軸部１５がスイッチ部１９を確実に押圧してオン動作させるように構成されている。 As a result, as shown in FIGS. 2 to 4, the cushioning body 13 is pressed by the head portion 16 of the operation member 12, and the first outer wall portion 21b and the cylindrical portion 21a of the elastic member 21 are elastically deformed. When the material 20 is elastically deformed like a liquid, the amount of deformation of both the cylindrical portion 21a and the first outer wall portion 21b and the gel material 20 causes the shaft portion 15 to reliably engage the switch portion 19. It is configured to be turned on by pressing.

この場合、緩衝体１３は、図２～図４に示すように、操作部材１２の軸部１５がスイッチ部１９から離れる際に、弾性材２１の円筒部２１ａと第１外壁部２１ｂとが弾性復帰して元の形状に戻ると共に、ゲル状の素材２０が弾性材２１の弾性復帰よりも遅れてゆっくり弾性的に復帰して元の形状に戻ることにより、操作部材１２を本体ケース４の外部に向けて押し出して初期状態に戻すように構成されている。 In this case, as shown in FIGS. 2 to 4, when the shaft portion 15 of the operation member 12 is separated from the switch portion 19, the cylindrical portion 21a of the elastic member 21 and the first outer wall portion 21b of the cushioning body 13 are elastic. The operation member 12 is returned to the outside of the main body case 4 by elastically returning to its original shape slowly with a delay from the elastic recovery of the elastic member 21 and returning to its original shape. and is configured to return to the initial state.

また、この緩衝体１３は、図２～図４に示すように、操作部材１２の頭部１６が外部から衝撃などの強い力を受けた際に、弾性材２１の円筒部２１ａと第１外壁部２１ｂとが急激に弾性変形しても、ゲル状の素材２０があまり変形せずに固体のように硬くなり、操作部材１２の軸部１５の内端部が本体ケース４内に大きく押し込まれないように構成されている。このため、スイッチ部１９は、操作部材１２の軸部１５によって接点板１９ｂが押されてもオン動作しないように構成されている。 2 to 4, when the head portion 16 of the operating member 12 receives a strong force such as an impact from the outside, the cushioning body 13 separates the cylindrical portion 21a of the elastic member 21 from the first outer wall. Even if the portion 21b is suddenly elastically deformed, the gel-like material 20 does not deform so much and becomes hard like a solid, and the inner end portion of the shaft portion 15 of the operation member 12 is largely pushed into the main body case 4. configured to prevent Therefore, the switch portion 19 is configured so as not to turn on even when the contact plate 19b is pushed by the shaft portion 15 of the operating member 12 .

この場合、緩衝体１３は、図２～図４に示すように、操作部材１２の軸部１５がスイッチ部１９から離れる際に、ゲル状の素材２０があまり変形していないため、弾性材２１の円筒部２１ａと第１外壁部２１ｂとが弾性復帰して元の形状に戻ることにより、操作部材１２を本体ケース４の外部に向けて押し出して、初期状態に戻すように構成されている。 In this case, as shown in FIGS. 2 to 4, when the shaft portion 15 of the operation member 12 separates from the switch portion 19, the cushioning body 13 has the elastic material 21 because the gel-like material 20 is not deformed so much. When the cylindrical portion 21a and the first outer wall portion 21b are elastically restored to their original shapes, the operating member 12 is pushed out of the main body case 4 and returned to its initial state.

また、このスイッチ装置３は、図２に示すように、緩衝体１３の外周面と本体ケース４の収納凹部１４の内周面との間に緩衝体１３の変形を許容するための隙間Ｒが設けられた構造になっている。この隙間Ｒは、緩衝体１３が操作部材１２の頭部１６によって押されて圧縮される際に、緩衝体１３を軸部１５の軸方向と直交する径方向に広がるように弾性変形させて、ダイラタンシー特性を有するゲル状の素材２０が体積圧縮されないように構成されている。 Also, in this switch device 3, as shown in FIG. It has a set structure. This gap R elastically deforms the buffer 13 so as to expand in the radial direction orthogonal to the axial direction of the shaft portion 15 when the buffer 13 is pushed and compressed by the head portion 16 of the operation member 12. A gel-like material 20 having a dilatancy characteristic is configured so as not to be volume-compressed.

また、このスイッチ装置３は、図２に示すように、緩衝体１３と操作部材１２の頭部１６との間に、頭部１６の押圧力を緩衝体１３の全体に亘って伝えるための硬質のプレート２２が配置された構造になっている。このプレート２２は、ステンレスなどの金属または硬質の合成樹脂によって平板状に形成されている。このプレート２２は、その外形が緩衝体１３の外形と同じか、それよりも少し大きく形成され、中心部に軸部１５が挿入する挿入孔２２ａが設けられた構造になっている。 Moreover, as shown in FIG. 2, the switch device 3 is provided between the shock absorber 13 and the head 16 of the operating member 12 by a rigid body for transmitting the pressing force of the head 16 over the shock absorber 13 as a whole. plate 22 is arranged. The plate 22 is made of a metal such as stainless steel or hard synthetic resin in a flat shape. The plate 22 has an outer shape that is the same as or slightly larger than the outer shape of the buffer 13, and has a structure in which an insertion hole 22a into which the shaft portion 15 is inserted is provided in the center.

これにより、プレート２２は、図２に示すように、操作部材１２の頭部１６の押圧領域部である頭部１６の内端面が押し当てられた際に、プレート２２に対面する緩衝体１３の外側面、つまり弾性材２１の第２外壁部２１ｃの全面に押し当てられることにより、緩衝体１３の長手方向の両側が頭部１６よりも突出していても、緩衝体１３が部分的に変形することがなく、緩衝体１３をその全体に亘って均一に押圧して、緩衝体１３の全体を均一に変形させるように構成されている。この場合、プレート２２は、長手方向の両側が頭部１６よりも突出していても、外部から見えないようにベゼルケース５で覆われている。 As a result, the plate 22, as shown in FIG. 2, is the cushioning body 13 that faces the plate 22 when the inner end surface of the head 16, which is the pressing area of the head 16 of the operation member 12, is pressed. By being pressed against the outer surface, that is, the entire surface of the second outer wall portion 21c of the elastic member 21, the buffer 13 is partially deformed even if both sides in the longitudinal direction of the buffer 13 protrude beyond the head 16. The shock absorber 13 is uniformly pressed over its entirety, and the entire shock absorber 13 is uniformly deformed. In this case, the plate 22 is covered with the bezel case 5 so as not to be seen from the outside even if both longitudinal sides of the plate 22 protrude beyond the head 16 .

また、収納凹部１４の底面に対面する弾性材２１の第２壁部２１ｃには、図２～図４に示すように、複数の弾性突起２３が操作部材１２の軸部１５のスライド方向に向けて突出して設けられている。これら複数の弾性突起２３は、本体ケー４の収納凹部１４の底面に対向する第２壁部２１ｃの端面に設けられている。 2 to 4, the second wall portion 21c of the elastic member 21 facing the bottom surface of the storage recess 14 has a plurality of elastic protrusions 23 directed in the sliding direction of the shaft portion 15 of the operating member 12. It is provided protruding from the The plurality of elastic projections 23 are provided on the end surface of the second wall portion 21c facing the bottom surface of the housing recess 14 of the main body case 4. As shown in FIG.

この場合、弾性材２１の第２壁部２１ｃの内面には、図４（ｂ）に示すように、複数の弾性突起２３に対応する凹部２３ａがそれぞれ設けられている。これにより、複数の弾性突起２３は、操作部材１２の頭部１６が外部から押された際に、収納凹部１４の底面に押し当てられた状態で、弾性材２１の円筒部２１ａと第１外壁部２１ｂと共に弾性変形するように構成されている。また、複数の弾性突起２３は、収納凹部１４内に配置された際に、緩衝体１３のガタ付きを防ぐように構成されている。 In this case, recesses 23a corresponding to the plurality of elastic projections 23 are provided on the inner surface of the second wall portion 21c of the elastic member 21, as shown in FIG. 4(b). As a result, when the head portion 16 of the operating member 12 is pushed from the outside, the plurality of elastic projections 23 are pressed against the bottom surface of the storage recess 14 so that the cylindrical portion 21a of the elastic member 21 and the first outer wall are in contact with each other. It is configured to elastically deform together with the portion 21b. In addition, the plurality of elastic projections 23 are configured to prevent the damping body 13 from rattling when it is arranged in the storage recess 14 .

次に、このような腕時計のスイッチ装置３の作用について説明する。
このスイッチ装置３は、通常の初期状態のときに、操作部材１２が緩衝体１３のばね性によって腕時計ケース１の本体ケース４の外部に向けて押し出されている。すなわち、操作部材１２は、頭部１６が緩衝体１３の弾性材２１の弾力、つまり弾性材２１の円筒部２１ａ、第１外壁部２１ｂ、および複数の弾性突起２３の弾力によるばね力によって、本体ケース４の外部に向けて押し出され、軸部１５の内端部に設けられた抜止め部材１７が本体ケース４の内面に押し当てられている。 Next, the operation of the switch device 3 of such a wristwatch will be described.
In the normal initial state of the switch device 3 , the operating member 12 is pushed out of the body case 4 of the wristwatch case 1 by the springiness of the buffer 13 . That is, the head 16 of the operation member 12 is moved by the elastic force of the elastic member 21 of the buffer 13, that is, the elastic force of the cylindrical portion 21a, the first outer wall portion 21b, and the plurality of elastic projections 23 of the elastic member 21. A retaining member 17 , which is pushed out of the case 4 and provided at the inner end of the shaft portion 15 , is pressed against the inner surface of the main body case 4 .

この状態では、操作部材１２の軸部１５の内端部が時計モジュール１０のスイッチ部１９から離れているので、スイッチ部１９がオフ状態になっている。また、この状態では、操作部材１２の頭部１６がプレート２２と共に本体ケース４の外部に押し出されて、頭部１６の外端部がベゼルケース５の外部に突出している。このため、このスイッチ装置３では、操作部材１２の頭部１６を操作する際の操作性が良く、良好にかつ容易に操作することができる。 In this state, since the inner end of the shaft portion 15 of the operating member 12 is separated from the switch portion 19 of the timepiece module 10, the switch portion 19 is turned off. Also, in this state, the head 16 of the operation member 12 is pushed out of the main body case 4 together with the plate 22 , and the outer end of the head 16 projects out of the bezel case 5 . Therefore, the switch device 3 has good operability when the head portion 16 of the operation member 12 is operated, and can be operated satisfactorily and easily.

そして、このスイッチ装置３を操作してスイッチ部１９をオン動作させる際には、操作部材１２の頭部１６を緩衝体１３の弾性材２１の弾力に抗して押圧する。すなわち、スイッチ部１９をスイッチ操作させる程度の押圧力、つまり低衝撃の力で頭部１６を押すと、頭部１６の押圧領域部である頭部１６の内端面がプレート２２を介して緩衝体１３を押圧する。 When the switch device 3 is operated to turn on the switch portion 19 , the head portion 16 of the operating member 12 is pressed against the elasticity of the elastic member 21 of the buffer 13 . That is, when the head 16 is pressed with a pressing force that causes the switch portion 19 to switch, that is, with a low impact force, the inner end surface of the head 16, which is the pressing area of the head 16, is pushed through the plate 22 into the cushioning body. Press 13.

すると、頭部１６の押圧動作に応じて弾性材２１の円筒部２１ａ、第１外壁部２１ｂ、および複数の弾性突起２３がプレート２２によって弾性変形すると共に、ゲル状の素材２０が液体のように弾性的にゆっくり変形する。このときには、頭部１６によってプレート２２が押され、このプレート２２によって緩衝体１３が押されるので、緩衝体１３の長手方向の両側が頭部１６よりも突出していても、緩衝体１３が部分的に変形することがなく、緩衝体１３の全体が均一に押圧される。 Then, the cylindrical portion 21a, the first outer wall portion 21b, and the plurality of elastic projections 23 of the elastic member 21 are elastically deformed by the plate 22 in accordance with the pressing operation of the head 16, and the gel-like material 20 is made liquid-like. It deforms slowly elastically. At this time, the plate 22 is pushed by the head 16, and the buffer 13 is pushed by this plate 22. Therefore, even if both sides of the buffer 13 in the longitudinal direction protrude beyond the head 16, the buffer 13 is partially The entire shock absorber 13 is uniformly pressed without being deformed.

これにより、操作部材１２の軸部１５が本体ケース４の貫通孔１１と緩衝体１３の円筒部２１ａ内をスライドして、軸部１５の内端部が本体ケース４の内部に突出する。このときには、軸部１５の内端部に設けられた抜止め部材１７が本体ケース４の内周面から離れて、軸部１５の内端部が時計モジュール１０のスイッチ部１９の接点板１９ｂを押圧してスイッチ本体１９ａに押し当てる。これにより、スイッチ部１９が軸部１５によって押されてオン動作する。 As a result, the shaft portion 15 of the operating member 12 slides in the through hole 11 of the body case 4 and the cylindrical portion 21 a of the buffer 13 , and the inner end portion of the shaft portion 15 protrudes into the body case 4 . At this time, the retaining member 17 provided at the inner end of the shaft portion 15 is separated from the inner peripheral surface of the main body case 4, and the inner end portion of the shaft portion 15 contacts the contact plate 19b of the switch portion 19 of the timepiece module 10. It is pressed against the switch body 19a. As a result, the switch portion 19 is pushed by the shaft portion 15 and turned on.

この状態で、操作部材１２が初期状態に戻る際には、弾性材２１の円筒部２１ａと第１外壁部２１ｂと複数の弾性突起２３とが弾性復帰して元の形状に戻ると共に、ゲル状の素材２０が弾性材２１の弾性復帰よりも遅れてゆっくり弾性的に復帰して元の形状に戻る。これにより、操作部材１２の頭部１６がプレート２２と共に本体ケース４の外部に押し出される。すると、軸部１５の内端部が時計モジュール１０のスイッチ部１９から離れて、スイッチ部１９をオフ状態にし、軸部１５の内端部の抜止め部材１７が本体ケース４の内周面に押し当てられて、操作部材１２が初期状態に戻る。 In this state, when the operation member 12 returns to the initial state, the cylindrical portion 21a, the first outer wall portion 21b, and the plurality of elastic projections 23 of the elastic member 21 are elastically restored to their original shapes, and the gel-like state is restored. The material 20 recovers slowly elastically behind the elastic recovery of the elastic member 21 and returns to its original shape. As a result, the head portion 16 of the operating member 12 is pushed out of the main body case 4 together with the plate 22 . Then, the inner end of the shaft portion 15 separates from the switch portion 19 of the timepiece module 10 to turn off the switch portion 19 , and the retainer member 17 on the inner end portion of the shaft portion 15 contacts the inner peripheral surface of the main body case 4 . The operating member 12 is returned to its initial state by being pressed.

一方、操作部材１２の頭部１６が外部から衝撃などの強い力を受けた際には、その高衝撃によって弾性材２１の円筒部２１ａと第１外壁部２１ｂと複数の弾性突起２３とが急激に弾性変形しても、ゲル状の素材２０があまり変形せずに固体のように硬くなるため、操作部材１２の軸部１５の内端部が本体ケース４内に大きく押し込まれることがない。このため、スイッチ部１９は、接点板１９ｂが操作部材１２の軸部１５によって押されても、接点板１９ｂがスイッチ本体１９ａに押し付けられることがないので、オン動作しない。これにより、本体ケース４内の時計モジュール１０の破損が防げる。 On the other hand, when the head portion 16 of the operating member 12 receives a strong force such as a shock from the outside, the cylindrical portion 21a of the elastic member 21, the first outer wall portion 21b, and the plurality of elastic projections 23 are suddenly deformed by the high shock. Even if it is elastically deformed, the gel-like material 20 does not deform so much and becomes hard like a solid. Therefore, even if the contact plate 19b is pushed by the shaft portion 15 of the operating member 12, the switch portion 19 does not turn on because the contact plate 19b is not pressed against the switch body 19a. This prevents the timepiece module 10 in the main body case 4 from being damaged.

この状態で、操作部材１２が初期状態に戻る際には、ゲル状の素材２０があまり変形していないため、弾性材２１の円筒部２１ａと第１外壁部２１ｂと複数の弾性突起２３とが弾性復帰して元の形状に戻る。これにより、操作部材１２の頭部１６がプレート２２を介して本体ケース４の外部に押し出されて、軸部１５の内端部が時計モジュール１０のスイッチ部１９の接点板１９ｂから離れる。このため、スイッチ部１９がオフ状態を維持したままで、軸部１５の内端部の抜止め部材１７が本体ケース４の内周面に押し当てられて、操作部材１２が初期状態に戻る。 In this state, when the operating member 12 returns to its initial state, the gel-like material 20 is not deformed so much that the cylindrical portion 21a of the elastic member 21, the first outer wall portion 21b, and the plurality of elastic projections 23 are aligned. Elastically returns to its original shape. As a result, the head portion 16 of the operating member 12 is pushed out of the main body case 4 through the plate 22 , and the inner end of the shaft portion 15 is separated from the contact plate 19 b of the switch portion 19 of the timepiece module 10 . Therefore, while the switch portion 19 remains in the OFF state, the retaining member 17 at the inner end portion of the shaft portion 15 is pressed against the inner peripheral surface of the main body case 4, and the operating member 12 returns to its initial state.

このように、この腕時計のスイッチ装置３によれば、内部のスイッチ部１９に対応して貫通孔１１が設けられた本体ケース４と、この本体ケース４の貫通孔１１にスライド可能に挿入される軸部１５およびこの軸部１５の外端部に設けられて本体ケース４の外部に配置される頭部１６を備えた操作部材１２と、頭部１６と本体ケース４との間に配置され、ダイラタンシー特性を有するゲル状の素材２０を弾性材２１で包んだばね性を備えた緩衝体１３と、を備えていることにより、操作性を確保することができ、かつ衝撃による時計モジュール１０の破損を防ぐことができる。 As described above, according to the switch device 3 of the wristwatch, the main body case 4 is provided with the through hole 11 corresponding to the internal switch portion 19, and the main body case 4 is slidably inserted into the through hole 11 of the main body case 4. an operation member 12 having a shaft portion 15 and a head portion 16 provided at the outer end portion of the shaft portion 15 and disposed outside the main body case 4; Equipped with a cushioning body 13 having a spring property in which a gel-like material 20 having dilatancy characteristics is wrapped in an elastic material 21, it is possible to ensure operability and prevent damage to the timepiece module 10 due to impact. can be prevented.

すなわち、このスイッチ装置３では、緩衝体１３の弾性材２１が弾性変形する程度の低押圧力で操作部材１２の頭部１６を押圧操作してスイッチ部１９をオン動作させる際に、緩衝体１３の弾性材２１が弾性変形すると共に、緩衝体１３のゲル状の素材２０が液体のように弾性的に変形するので、操作部材１２の軸部１５によって本体ケース４内のスイッチ部１９を確実にかつ良好にオン動作させることができ、これにより操作性を確保することができる。 That is, in the switch device 3, when the head portion 16 of the operation member 12 is pressed with a low pressing force that elastically deforms the elastic member 21 of the buffer 13 to turn on the switch portion 19, the buffer 13 The elastic material 21 of the shock absorber 13 is elastically deformed, and the gel-like material 20 of the buffer 13 is elastically deformed like liquid. In addition, the ON operation can be performed satisfactorily, thereby ensuring operability.

また、このスイッチ装置３では、操作部材１２の頭部１６が本体ケース４の外部から衝撃などの強い力を受けた際に、弾性材２１が急激に弾性変形しても、ゲル状の素材２０があまり変形せずに固体のように硬くなるため、操作部材１２の軸部１５の内端部が本体ケース４内に大きく押し込まれることがない。このため、操作部材１２の軸部１５によってスイッチ部１９がオン動作することがなく、本体ケース４内の時計モジュール１０が軸部１５によって破損しないようにすることができる。 In addition, in the switch device 3, even if the head portion 16 of the operating member 12 receives a strong force such as an impact from the outside of the main body case 4, even if the elastic member 21 is suddenly elastically deformed, the gel-like material 20 is The inner end portion of the shaft portion 15 of the operation member 12 is not greatly pushed into the main body case 4 because the shaft portion 15 of the operation member 12 is hardened like a solid without being deformed so much. Therefore, the switch portion 19 is not turned on by the shaft portion 15 of the operating member 12 , and the timepiece module 10 in the main body case 4 can be prevented from being damaged by the shaft portion 15 .

この場合、操作部材１２の頭部１６は、本体ケース４の外部に配置された状態で、本体ケース４の外周を覆うベゼルケース５から外部に突出して設けられていることにより、頭部１６を容易にかつ良好に操作することができ、これによっても操作性を向上させることができる。また、このように頭部１６がベゼルケース５の外部に突出していることにより、頭部１６の大きさや形状を自由に設定することができるので、腕時計全体のデザイン性を高めることができる。 In this case, the head portion 16 of the operation member 12 is arranged outside the main body case 4 and protrudes outside from the bezel case 5 that covers the outer periphery of the main body case 4 . It can be operated easily and satisfactorily, which also improves the operability. Moreover, since the head 16 protrudes outside the bezel case 5 in this way, the size and shape of the head 16 can be freely set, so that the overall design of the wristwatch can be improved.

また、このスイッチ装置では、操作部材１２の頭部１６が緩衝体１３に押圧力を伝える押圧領域部である頭部１６の内端面を備え、この押圧領域部である頭部１６の内端面が緩衝体１３における軸部１５に垂直な断面に対応していることにより、頭部１６が押された際に、頭部１６の押圧領域部である頭部１６の内端面によって頭部１６の押圧力を緩衝体１３に確実にかつ良好に伝えることができる。 Further, in this switch device, the head 16 of the operating member 12 has an inner end face of the head 16 which is a pressing area that transmits a pressing force to the cushioning body 13, and the inner end of the head 16 which is the pressing area is Corresponding to the cross section perpendicular to the shaft portion 15 in the cushioning body 13, when the head portion 16 is pushed, the head portion 16 is pushed by the inner end surface of the head portion 16, which is the pushing area portion of the head portion 16. Pressure can be reliably and well transmitted to the buffer 13 .

この場合、緩衝体１３と操作部材１２の頭部１６の押圧領域部である頭部１６の内端面との間には、緩衝体１３の全体に亘って頭部１６の押圧力を伝えるためのプレート２２が配置されていることにより、頭部１６が押されて、頭部１６の内端面がプレート２２に押し当てられた際に、プレート２２に対面する緩衝体１３の外側面の全面にプレート２２を押し当てることができる。 In this case, between the cushioning body 13 and the inner end surface of the head 16 of the operation member 12, which is the pressing area of the head 16, there is provided a mechanism for transmitting the pressing force of the head 16 over the entire cushioning body 13. By arranging the plate 22, when the head 16 is pushed and the inner end surface of the head 16 is pressed against the plate 22, the entire outer surface of the buffer 13 facing the plate 22 is plated. 22 can be pressed.

このため、このスイッチ装置では、緩衝体１３の長手方向の両側が頭部１６の押圧領域部である頭部１６の内端面よりも突出していても、緩衝体１３が部分的に変形することがなく、緩衝体１３をその全体に亘って均一に押圧して、緩衝体１３の全体を均一にかつ良好に変形させることができる。 Therefore, in this switch device, even if both longitudinal sides of the damping body 13 protrude beyond the inner end surface of the head 16, which is the pressing region of the head 16, the damping body 13 is not partially deformed. Therefore, the shock absorber 13 can be evenly and favorably deformed by pressing the shock absorber 13 uniformly over its entirety.

この場合、緩衝体１３は、ゲル状の素材２０が液体のように変形する際に、弾性材２１が、操作部材１２の操作ストロークの範囲内で、操作部材１２の頭部１６によって押圧されて弾性変形し、この弾性変形の復元力によって操作部材１２を初期状態に復帰させることにより、弾性材２１をばね部材として機能させることができるので、通常のスイッチ装置と同様に使用することができ、これにより使い勝手の良いものを提供することができる。 In this case, when the gel-like material 20 is deformed like a liquid, the cushioning body 13 is such that the elastic material 21 is pressed by the head 16 of the operation member 12 within the range of the operation stroke of the operation member 12. By elastically deforming and restoring the operation member 12 to the initial state by the restoring force of this elastic deformation, the elastic member 21 can function as a spring member, so that it can be used in the same way as a normal switch device. This makes it possible to provide a product that is easy to use.

また、ダイラタンシー特性を有するゲル状の素材２０は、操作部材１２が弾性材２１を弾性変形させる程度の低押圧力でスイッチ部１９をスイッチ操作させた際に、液体のように弾性的に変形し、衝撃などの強い力が加わった際にあまり変形せずに固体のように硬くなることにより、操作部材１２の操作性を確保することができると共に、衝撃によるスイッチ部１９および時計モジュール１０の破損を防ぐことができる。 In addition, the gel-like material 20 having a dilatancy characteristic is elastically deformed like a liquid when the operating member 12 switches the switch portion 19 with a low pressing force that causes the elastic member 21 to be elastically deformed. , when a strong force such as an impact is applied, it does not deform much and hardens like a solid, so that the operability of the operation member 12 can be ensured, and the switch part 19 and the timepiece module 10 will not be damaged by the impact. can be prevented.

すなわち、ダイラタンシー特性を有するゲル状の素材２０は、低衝撃つまり低い周波数の衝撃に対して低反発で、液体のように弾力的にゆっくり変形し、高衝撃つまり高い周波数の衝撃に対して高反発で弾力が低下して、あまり変形せずに固体のように硬くなることにより、操作部材１２がスイッチ部１９をスイッチ操作させる程度の低衝撃の押圧力で押圧された際に、弾性材２１と共に弾性的に変形するので、スイッチ部１９を良好にオン動作させることができる。 That is, the gel-like material 20 having the dilatancy characteristic has low repulsion against low impact, that is, low frequency impact, elastically deforms slowly like a liquid, and has high resilience against high impact, that is, high frequency impact. When the operating member 12 is pressed with a low impact force that causes the switch portion 19 to switch, the elastic member 21 and the elastic member 21 are pressed together. Since it deforms elastically, the switch part 19 can be satisfactorily turned on.

また、このゲル状の素材２０は、操作部材１２の頭部１６が衝撃などの高衝撃を受けた際に、弾性材２１が弾性変形しても、衝撃に対して高反発で弾力が低下して、あまり変形せずに固体のように硬くなるので、スイッチ部１９をオン動作させずに、オフ状態を維持させることができ、これにより耐衝撃性を確保することができると共に、高衝撃によるスイッチ部１９および時計モジュール１０の破損を防ぐことができる。 In addition, even if the elastic member 21 is elastically deformed when the head portion 16 of the operating member 12 receives a high impact such as an impact, the gel-like material 20 has a high resilience against the impact and the elasticity is reduced. As a result, the switch portion 19 does not deform much and becomes hard like a solid, so that the switch portion 19 can be maintained in the off state without being turned on. Damage to the switch section 19 and the clock module 10 can be prevented.

すなわち、このスイッチ装置３では、操作部材１２の頭部１６が押されてスイッチ操作する際に、弾性材２１と共にゲル状の素材２０が液体のように弾性的に変形することにより、軸部１５がスイッチ部１９を押してオン動作させることができ、また操作部材１２の軸部１５がスイッチ部１９から離れる際に、弾性材２１が弾性復帰して元の形状に戻ると共に、ゲル状の素材２０が弾性材２１の弾性復帰よりも遅れてゆっくり弾性的に復帰して元の形状に戻るので、操作部材１２を本体ケース４の外部に向けて押し出して初期状態に戻すことができる。 That is, in the switch device 3, when the head portion 16 of the operation member 12 is pressed to operate the switch, the gel-like material 20 elastically deforms like a liquid together with the elastic member 21, thereby can push the switch portion 19 to turn it on, and when the shaft portion 15 of the operating member 12 is separated from the switch portion 19, the elastic material 21 is elastically restored to its original shape, and the gel-like material 20 is delayed from the elastic recovery of the elastic member 21 and returns to its original shape, the operation member 12 can be pushed out of the main body case 4 and returned to its initial state.

また、このスイッチ装置３では、操作部材１２の頭部１６が外部から衝撃などの強い力を受けた際に、弾性材２１が急激に弾性変形しても、ゲル状の素材２０があまり変形せずに固体のように硬くなるので、操作部材１２の軸部１５を本体ケース４内に大きく押し込まれないようにすることができ、これによりスイッチ部１９をオン動作させないようにすることができると共に、スイッチ部１９および時計モジュール１０の破損を防ぐことができる。 Further, in the switch device 3, when the head portion 16 of the operating member 12 receives a strong force such as an impact from the outside, even if the elastic member 21 is suddenly elastically deformed, the gel-like material 20 is hardly deformed. As a result, the shaft portion 15 of the operation member 12 can be prevented from being largely pushed into the main body case 4, thereby preventing the switch portion 19 from being turned on. , the switch section 19 and the clock module 10 can be prevented from being damaged.

この場合、このスイッチ装置３では、操作部材１２の軸部１５がスイッチ部１９から離れる際に、ゲル状の素材２０があまり変形していないため、弾性材２１のみが弾性復帰して元の形状に戻るので、操作部材１２を本体ケース４の外部に向けて押し出して初期状態に戻すことができる。 In this case, in this switch device 3, when the shaft portion 15 of the operating member 12 is separated from the switch portion 19, the gel-like material 20 is not deformed so much, so only the elastic material 21 is elastically restored to its original shape. , the operation member 12 can be pushed out of the main body case 4 and returned to the initial state.

また、この緩衝体１３は、ダイラタンシー特性を有するゲル状の素材２０が固体のようになる場合、操作部材１２の操作ストロークＳ１とスイッチ部１９の動作ストロークＳ２との差（Ｓ１－Ｓ２）の範囲内で変形することにより、操作部材１２が押されてスイッチ操作する際に、操作部材１２の操作ストロークＳ１とスイッチ部１９の動作ストロークＳ２との差の範囲内において、ゲル状の素材２０を弾性材２１と共に液体のように弾性的に変形させることができるので、スイッチ部１９を確実にかつ良好にオン動作させることができる。 In addition, when the gel-like material 20 having the dilatancy characteristic becomes solid, the buffer 13 is in the range of the difference (S1-S2) between the operation stroke S1 of the operation member 12 and the operation stroke S2 of the switch portion 19. When the operation member 12 is pressed to operate the switch, the gel material 20 is elastically deformed within the range of the difference between the operation stroke S1 of the operation member 12 and the operation stroke S2 of the switch portion 19. Since it can be elastically deformed together with the material 21 like a liquid, the switch portion 19 can be reliably and favorably turned on.

この場合、緩衝体１３は、操作部材１２の頭部１６が外部から衝撃などの強い力を受けた際に、弾性材２１が急激に弾性変形しても、ゲル状の素材２０があまり変形せずに固体のように硬くなるので、操作部材１２の軸部１５を本体ケース４内に大きく押し込まれないようにすることができ、これにより軸部１５がスイッチ部１９の接点板１９ｂを押しても、接点板１９ｂがスイッチ本体１９ａに押し当れることがないので、スイッチ部１９をオン動作させずに、オフ状態を維持させることができる。 In this case, when the head portion 16 of the operation member 12 receives a strong force such as an impact from the outside, the cushioning body 13 does not deform the gel-like material 20 very much even if the elastic member 21 is suddenly elastically deformed. Since the shaft portion 15 of the operating member 12 is not pushed into the main body case 4 by a large amount, even if the shaft portion 15 pushes the contact plate 19b of the switch portion 19, the contact plate 19b of the switch portion 19 is hardened. Since the contact plate 19b is not pressed against the switch body 19a, the switch portion 19 can be maintained in the off state without being turned on.

また、このスイッチ装置３では、弾性材２１が、操作部材１２の軸部１５のスライド方向と平行な第１外壁部２１ｂと、軸部１５のスライド方向と直交する第２外壁部２１ｃと、を備え、第１外壁部２１ｂの肉厚が第２外壁部２１ｃの肉厚よりも厚く形成されていることにより、操作部材１２の頭部１６によって弾性材２１が押圧された際に、第１外壁部２１ｂを軸部１５の軸方向に確実に弾性変形させることができるので、第１外壁部２１ｂによってばね性を確保することができる。 Further, in this switch device 3, the elastic member 21 has a first outer wall portion 21b parallel to the sliding direction of the shaft portion 15 of the operating member 12 and a second outer wall portion 21c perpendicular to the sliding direction of the shaft portion 15. In addition, since the thickness of the first outer wall portion 21b is formed to be thicker than the thickness of the second outer wall portion 21c, when the elastic member 21 is pressed by the head portion 16 of the operation member 12, the first outer wall portion Since the portion 21b can be reliably elastically deformed in the axial direction of the shaft portion 15, springiness can be ensured by the first outer wall portion 21b.

この場合、第１外壁部２１ｂは、緩衝体１３が頭部１６によって押された際の変形量が、ダイラタンシー特性を有するゲル状の素材２０の変形量よりも大きいことにより、弾性材２１によるばね性を確保することができる。このため、この第１外壁部２１ｂは、操作部材１２の頭部１６によって弾性変形すると共に、ゲル状の素材２０が液体のように弾性的に変形した際に、第１外壁部２１ｂの変形量とゲル状の素材２０の変形量とによって軸部１５がスイッチ部１９を確実に押圧してオン動作させることができる。 In this case, the amount of deformation of the first outer wall portion 21b when the cushioning body 13 is pushed by the head 16 is larger than the amount of deformation of the gel-like material 20 having dilatancy characteristics, so that the elastic material 21 provides a spring force. can ensure the integrity of the Therefore, the first outer wall portion 21b is elastically deformed by the head portion 16 of the operation member 12, and when the gel-like material 20 is elastically deformed like a liquid, the deformation amount of the first outer wall portion 21b is and the amount of deformation of the gel-like material 20, the shaft portion 15 can reliably press the switch portion 19 to turn it on.

また、このスイッチ装置３では、緩衝体１３が配置される本体ケース４の収納凹部１４の内周面と緩衝体１３の外周面との間に緩衝体１３の変形を許容する隙間Ｒが設けられていることにより、緩衝体１３が操作部材１２の頭部１６によって押されて圧縮される際に、緩衝体１３を軸部１５の軸方向と直交する径方向に広がるように弾性変形させることができ、これによりゲル状の素材２０が体積圧縮されないため、ゲル状の素材２０のダイラタンシー特性を発揮させることができ、弾性材２１およびゲル状の素材２０を確実にかつ良好に変形させることができる。 Further, in the switch device 3, a gap R is provided between the inner peripheral surface of the housing recess 14 of the main body case 4 in which the buffer 13 is arranged and the outer peripheral surface of the buffer 13 to allow deformation of the buffer 13. Therefore, when the buffer 13 is pushed and compressed by the head portion 16 of the operation member 12, the buffer 13 can be elastically deformed so as to expand in the radial direction orthogonal to the axial direction of the shaft portion 15. Since the gel-like material 20 is not volume-compressed, the dilatancy characteristics of the gel-like material 20 can be exhibited, and the elastic material 21 and the gel-like material 20 can be reliably and favorably deformed. .

このため、このスイッチ装置３では、操作部材１２の頭部１６によって緩衝体１３が低衝撃で押圧された際に、弾性材２１を確実に弾性変形させることができると共に、ゲル状の素材２０を液体のように弾力的に変形させることができ、また、操作部材１２の頭部１６によって緩衝体１３が高衝撃で押圧された際に、弾性材２１が弾性変形しても、ゲル状の素材２０があまり変形せずに、ゲル状の素材２０を固体のように硬くさせることができる。 Therefore, in the switch device 3, when the buffer 13 is pressed by the head 16 of the operating member 12 with a low impact, the elastic member 21 can be reliably elastically deformed, and the gel-like material 20 can be displaced. It can be elastically deformed like a liquid, and even if the elastic material 21 is elastically deformed when the buffer 13 is pressed by the head 16 of the operation member 12 with a high impact, the gel-like material remains. The gel-like material 20 can be hardened like a solid without deforming the gel 20 too much.

さらに、このスイッチ装置３では、弾性材２１の第２外壁部２１ｃに複数の弾性突起２３が操作部材１２の軸部１５のスライド方向に向けて突出して設けられていることにより、操作部材１２の頭部１６が外部から押された際に、複数の弾性突起２３を収納凹部１４の底面に押し当てて、弾性材２１の円筒部２１ａと第１外壁部２１ｂと共に複数の弾性突起２３を良好に弾性変形させることができ、これによっても弾性材２１によるばね性を確保して、操作部材１２の操作性を向上させることができると共に、収納凹部１４内での緩衝体１３のガタ付きを防ぐことができる。 Further, in the switch device 3, the plurality of elastic protrusions 23 are provided on the second outer wall portion 21c of the elastic member 21 so as to protrude in the sliding direction of the shaft portion 15 of the operating member 12. When the head 16 is pushed from the outside, the plurality of elastic projections 23 are pressed against the bottom surface of the storage recess 14, and the plurality of elastic projections 23 are well formed together with the cylindrical portion 21a and the first outer wall portion 21b of the elastic member 21. It can be elastically deformed, and this also ensures the springiness of the elastic member 21, improving the operability of the operation member 12, and preventing the damping body 13 from rattling in the storage recess 14. can be done.

Even if it is smaller than the height, and even if the inner end surface of the head is provided with a concave portion or a convex portion, the plate 22 can uniformly press the cushioning body 13 to uniformly deform it.
