Description

本発明は、車両等に備えられた電子機器の操作に使用する回転操作装置に関するものである。 The present invention relates to a rotary operation device used for operation of an electronic device provided in a vehicle or the like.

従来、様々な電子機器に搭載される操作装置として、回転操作装置が知られている。このような回転操作装置は、例えば、自動車等の車両に搭載される場合、車両の電子機器、具体的には、空調装置やカーナビゲーションシステム、あるいはカーオーディオシステム等を操作するために用いられる。 Conventionally, a rotation operation device is known as an operation device mounted on various electronic devices. For example, when such a rotation operation device is mounted on a vehicle such as an automobile, it is used for operating an electronic device of the vehicle, specifically, an air conditioner, a car navigation system, a car audio system, or the like.

このような回転操作装置として、特許文献１には、特定の回転軸回りに回転操作される回転操作部材と、この回転操作部材を回転可能に保持するホルダーと、前記回転操作部材に対して相対回転するとともに当該回転操作部材に弾性的に接触する弾性部材とを備えたものが開示されている。前記弾性部材は、前記回転軸方向に弾性変形が可能なアーム部と、このアーム部から前記回転操作部材側に向かって突出する形状の第一のカム部とを有する。前記回転操作部材は、前記回転軸周りに形成された凹凸部からなる第二のカム部を有する。この第二のカム部は、前記第一のカム部に対向する部位に形成されており、それぞれが前記第一のカム部を係止可能な形状を有して前記回転軸周りに間欠的に配置された複数の凹部を有する。そして、前記弾性部材は、前記第一のカム部が前記第二のカム部に弾性的に接触されるように位置決めされている。よって、前記回転操作部材を回転操作すると前記第二のカム部が回転し、前記第一のカム部が前記凹部に順次係合していく。このことが操作者に操作感、すわなち、クリック感をもたらす。 As such a rotation operation device, Patent Document 1 discloses a rotation operation member that is rotated around a specific rotation axis, a holder that rotatably holds the rotation operation member, and a relative position with respect to the rotation operation member. An apparatus is disclosed that includes an elastic member that rotates and elastically contacts the rotational operation member. The elastic member includes an arm portion that can be elastically deformed in the rotation axis direction, and a first cam portion that is shaped to protrude from the arm portion toward the rotation operation member side. The rotation operation member has a second cam portion formed of an uneven portion formed around the rotation axis. The second cam portion is formed at a portion facing the first cam portion, and each has a shape capable of locking the first cam portion, and intermittently around the rotation shaft. It has the some recessed part arrange | positioned. The elastic member is positioned so that the first cam portion is in elastic contact with the second cam portion. Therefore, when the rotation operation member is rotated, the second cam portion is rotated, and the first cam portion is sequentially engaged with the recess. This brings an operational feeling, that is, a clicking feeling to the operator.

特開２００７−３２８９７４号公報JP 2007-328974 A

上記特許文献１に記載の回転操作装置は、クリック感を発生させるための専用の部材として前記弾性部材を必要とするため、部品点数が多くなり構造が複雑である上、各部品をそれぞれ個別に管理することも必要とされる。さらに、この回転操作装置は、その組立作業も容易ではない。すなわち、前記弾性部材は、前記回転操作部材に対して相対回転し、かつ、その第一カム部が前記第二カム部に弾性的に接触するように組み付けられる必要があるため、その組み付けには高い位置決め精度が要求される。この組み付け作業は、前記弾性部材が小さな部品であることも相まって、極めて煩雑なものである。 The rotational operation device described in Patent Document 1 requires the elastic member as a dedicated member for generating a click feeling, so that the number of parts is increased and the structure is complicated, and each part is individually provided. It is also necessary to manage. Furthermore, this rotary operation device is not easy to assemble. That is, the elastic member needs to be assembled so that it rotates relative to the rotation operation member and the first cam portion elastically contacts the second cam portion. High positioning accuracy is required. This assembling operation is extremely complicated due to the fact that the elastic member is a small component.

この発明は、上記のような課題を解決するためになされたものであり、操作者にクリック感を付与することが可能な回転操作装置であって、部品点数が少なく、組み立てが容易なものを提供することを目的とする。 The present invention has been made to solve the above-described problems, and is a rotary operation device capable of giving a feeling of clicking to an operator, which has a small number of parts and is easy to assemble. The purpose is to provide.

前記課題を解決するために、本発明は、特定の回転軸回りに回転操作される回転操作部材と、前記回転操作部材を前記回転軸回りに回転可能に保持するホルダーとを備える回転操作装置であって、前記回転操作部材は、前記回転軸を取り囲む周方向に全周にわたって凹部と凸部とが交互に配置された凹凸部を有し、前記ホルダーは、前記凹凸部よりも内側の位置で前記回転操作部材を回転可能に保持する保持壁を有し、この保持壁は、当該保持壁の他の部位に対して前記回転軸側に向かって撓み変形可能な撓み変形部と、この撓み変形部から外向きに突出するとともに前記凹部と係合可能な形状の突起とを有し、前記突起は、前記回転操作部材の回転操作に伴って前記撓み変形部を前記回転軸側へ変形させることにより前記回転軸側へ変位しながら前記凹部から離脱し、前記凸部を乗り越えたときに前記撓み変形部の弾性復帰力により外向きに付勢されることによって当該凸部と隣接する凹部に係合する回転操作装置を提供する。 In order to solve the above problems, the present invention provides a rotary operation device including a rotary operation member that is rotated around a specific rotation axis, and a holder that holds the rotation operation member rotatably around the rotation axis. The rotation operation member has an uneven portion in which concave portions and convex portions are alternately arranged over the entire circumference in a circumferential direction surrounding the rotation shaft, and the holder is located at a position inside the uneven portion. A holding wall that rotatably holds the rotation operation member, the holding wall being a bending deformation portion that can be bent and deformed toward the rotation shaft side with respect to other portions of the holding wall, and the bending deformation. A protrusion protruding outward from the portion and having a shape engageable with the recess, and the protrusion deforms the bending deformation portion toward the rotating shaft in accordance with a rotation operation of the rotation operation member. Is displaced to the rotating shaft side by Provided is a rotary operation device that engages with a concave portion adjacent to the convex portion by being biased outward by an elastic return force of the bending deformation portion when the convex portion is separated from the concave portion and gets over the convex portion. .

この発明の回転操作装置によれば、回転操作部材を保持するためのホルダーの保持壁に撓み変形部及び突起を設けることによって、前記ホルダーをクリック感を発生させるための構造として利用したので、前記回転操作部材を前記ホルダーに組み付けるだけで、前記回転操作部材の回転操作に伴って操作者にクリック感を付与可能な構造が得られる。そのため、クリック感を付与するための専用の部材、すなわち、前記回転操作部材や前記ホルダーとは別体の弾性部材が不要となり構造が簡素化される。具体的には、前記回転操作部材は、前記回転軸を取り囲む周方向に全周にわたって凹部と凸部とが交互に配置された凹凸部を有し、前記ホルダーの保持壁は、当該保持壁の他の部位に対して前記回転軸側に向かって撓み変形可能な撓み変形部と、この撓み変形部から外向きに突出するとともに前記凹部と係合可能な形状の突起とを有し、この突起は、前記回転操作部材の回転操作に伴って前記撓み変形部を前記回転軸側へ変形させることにより前記回転軸側へ変位しながら前記凹部から離脱し、前記凸部を乗り越えたときに前記撓み変形部の弾性復帰力により外向きに付勢されることによって当該凸部と隣接する凹部に係合するので、前記突起が前記凹部に係合した状態から前記回転操作部材を回転操作する際、前記突起が前記凹部から離脱して前記凸部に乗り上げるまでは、当該凹部３１の回転方向の部位と当接する突起を前記回転軸側に向かって変位させるための操作抵抗が発生する一方、当該突起が前記凸部に乗り上げてから当該凸部と隣接する凹部に係合するまでの間は、当該突起は前記回転方向からの抵抗を受けないので、当該突起が前記凸部に乗り上げるときに比べて発生する操作抵抗は小さくなる。そして、当該突起が前記凸部と隣接する凹部に係合したとき、操作者は再び当該突起を凸部に乗り上げさせるために必要な操作抵抗を感じる。この操作抵抗が操作者にクリック感として伝わる。 According to the rotation operation device of the present invention, the holder is used as a structure for generating a click feeling by providing a bending deformation portion and a protrusion on the holding wall of the holder for holding the rotation operation member. By simply assembling the rotary operation member to the holder, it is possible to obtain a structure that can give a click feeling to the operator as the rotary operation member rotates. Therefore, a dedicated member for giving a click feeling, that is, an elastic member separate from the rotation operation member and the holder is not required, and the structure is simplified. Specifically, the rotation operation member has a concavo-convex portion in which concave portions and convex portions are alternately arranged over the entire circumference in a circumferential direction surrounding the rotation shaft, and the holding wall of the holder is A protrusion having a shape that can be bent and deformed toward the rotating shaft with respect to another portion; and a protrusion that protrudes outward from the deformation portion and can be engaged with the recess. When the rotation operation member is rotated, the bending deformation portion is deformed to the rotation shaft side so as to be displaced toward the rotation shaft side while being detached from the recess portion, and when the protrusion is overcome, the bending operation is performed. Engaging the concave portion adjacent to the convex portion by being biased outward by the elastic return force of the deforming portion, when rotating the rotation operation member from the state where the projection is engaged with the concave portion, The protrusion is detached from the recess. Until the projection reaches the convex portion, an operation resistance for displacing the projection that contacts the portion of the concave portion 31 in the rotational direction is generated toward the rotation shaft side. Until the projection is engaged with the concave portion adjacent to the convex portion, the projection does not receive the resistance from the rotation direction, and therefore the operation resistance generated is smaller than when the projection rides on the convex portion. And when the said protrusion engages with the recessed part adjacent to the said convex part, an operator will feel the operation resistance required in order to make the said protrusion ride on a convex part again. This operation resistance is transmitted to the operator as a click feeling.

また、本発明において、前記回転操作部材は、前記保持壁の外側の位置で当該保持壁に保持されるとともにその前端部に前端面を有する被保持壁を有し、この被保持壁の前端面に前記回転軸方向に起伏するように前記凹凸部が形成されており、前記ホルダーは、前記回転操作部材の前記回転軸方向の後端部を受ける回転操作部材受け部を有し、前記突起は、前記被保持壁の前端面と当接することにより前記回転操作部材を前記回転操作部材受け部との間で前記回転軸方向の両側から挟み込み、かつ、前記回転軸方向と直交する径方向の内側に向かって前記凸部に乗り上げる形状を有することが好ましい。 In the present invention, the rotation operation member has a held wall that is held by the holding wall at a position outside the holding wall and has a front end surface at a front end portion thereof, and the front end surface of the held wall The concavo-convex part is formed so as to undulate in the rotation axis direction, and the holder has a rotation operation member receiving part for receiving a rear end part of the rotation operation member in the rotation axis direction, and the protrusion is The rotation operation member is sandwiched from both sides in the rotation axis direction with the rotation operation member receiving portion by contacting the front end surface of the held wall, and the inner side in the radial direction orthogonal to the rotation axis direction It is preferable to have a shape that rides on the convex portion toward.

このようにすれば、前記ホルダーの突起が、操作者にクリック感を付与する機能と、前記回転操作部材の前記ホルダーからの離脱を防止する機能とを両立する。 In this way, the protrusion of the holder has both a function of giving the operator a click feeling and a function of preventing the rotation operation member from being detached from the holder.

この場合において、前記突起は、前記凹部に嵌まり込むとともに前記径方向の内側への変位を伴いながら前記凸部を乗り越え可能な形状の嵌まり込み部と、前記被保持壁の前端面と接触することにより前記回転操作部材が前記ホルダーに対して前記回転軸方向に沿って前端側へ変位することを規制する規制部とを有し、前記規制部は、前記嵌まり込み部が前記凹部に嵌まり込んだ状態において前記被保持壁の前端面に接触するとともに、前記嵌まり込み部が前記凸部に乗り上げることを許容するように前記撓み変形部が撓み変形した状態においても前記被保持壁の前端面に接触するように前記撓み変形部から前記被保持壁に向かって突出する形状を有することが好ましい。 In this case, the protrusion contacts the front end surface of the held wall and the fitting portion having a shape that fits into the concave portion and can move over the convex portion while being displaced inward in the radial direction. And a restricting portion for restricting the rotation operation member from being displaced toward the front end side along the rotation axis direction with respect to the holder, and the restricting portion includes the fitting portion in the recess. The held wall is in contact with the front end surface of the held wall in the fitted state, and the bent deformation portion is bent and deformed so as to allow the fitted portion to run on the convex portion. It is preferable to have a shape that protrudes from the bending deformation portion toward the held wall so as to be in contact with the front end surface of the.

このようにすれば、前記回転操作部材が前記ホルダーに対してどのような回転角度となる場合であっても、前記規制部が前記被保持壁の前端面と接触するので、当該回転操作部材が前記ホルダーに対して前記回転軸方向に沿って前端側へ変位することが規制される。 According to this configuration, even if the rotation operation member is at any rotation angle with respect to the holder, the restricting portion comes into contact with the front end surface of the held wall. Displacement to the front end side along the rotational axis direction with respect to the holder is restricted.

また、本発明において、前記突起は、前記回転操作部材の回転方向の両端にそれぞれ形成された湾曲面を有し、各湾曲面は、前記回転方向の端部から前記回転方向の中央に向かうにしたがって前記径方向の外側に向かって突出し、かつ、その突出率が次第に小さくなる形状を有することが好ましい。 In the present invention, the protrusion has curved surfaces formed at both ends in the rotational direction of the rotational operation member, and each curved surface is directed from the end in the rotational direction toward the center in the rotational direction. Therefore, it is preferable to have a shape that protrudes toward the outside in the radial direction and that the protrusion rate gradually decreases.

このようにすれば、操作者に伝わるクリック感をより明瞭にすることができる。すなわち、前記突起は、前記回転方向の端部から前記回転方向の中央に向かうにしたがって前記径方向の外側に向かって突出し、かつ、その突出率が次第に小さくなる形状の湾曲面を有するので、前記回転操作部材を回転操作する際の操作力は、前記突起を前記凹部から離脱させるときに最大となる。よって、前記突起が前記凸部を乗り越えて当該凸部に隣接する凹部に係合したときに操作者の感じる操作抵抗が最大となるので、操作者に明瞭なクリック感が伝わる。 In this way, the click feeling transmitted to the operator can be made clearer. That is, the protrusion protrudes toward the outside in the radial direction from the end in the rotation direction toward the center of the rotation direction, and has a curved surface whose shape is gradually reduced. The operating force when rotating the rotary operation member is maximized when the projection is detached from the recess. Therefore, since the operation resistance felt by the operator is maximized when the protrusion gets over the protrusion and engages with the recess adjacent to the protrusion, a clear click feeling is transmitted to the operator.

以上のように、本発明によれば、操作者にクリック感を付与することが可能な回転操作装置であって、部品点数が少なく、組み立てが容易なものを提供することができる。 As described above, according to the present invention, it is possible to provide a rotary operation device capable of giving a click feeling to an operator, which has a small number of parts and can be easily assembled.

本発明の好ましい実施形態について、図１ないし図７を参照しながら説明する。 A preferred embodiment of the present invention will be described with reference to FIGS.

図１に示すように、本実施形態の回転操作装置は、特定の回転軸回りに回転操作される回転操作部材１０と、回転操作部材１０を保持するホルダー４０とを備える。なお、以下の説明において、この回転操作装置の回転軸方向における操作者が操作する側、すなわち、回転操作部材１０側を表面側又は前端側とし、その反対側を裏面側又は後端側とする。 As shown in FIG. 1, the rotation operation device of the present embodiment includes a rotation operation member 10 that is rotated around a specific rotation axis, and a holder 40 that holds the rotation operation member 10. In the following description, the side operated by the operator in the rotational axis direction of the rotary operation device, that is, the rotary operation member 10 side is the front side or the front end side, and the opposite side is the back side or the rear end side. .

回転操作部材１０は、操作者により回転操作されるダイアル２０と、このダイアル２０と共回りするように当該ダイアル２０と接続されるインナー３０とを有する。なお、本実施形態では、ダイアル２０とインナー３０とを別部材により構成しているが、これらは一体成形されてもよく、また、ダイアル２０は省略されてもよい。また、図２、図３及び図６では、ダイアル２０を省略している。 The rotary operation member 10 includes a dial 20 that is rotated by an operator, and an inner 30 that is connected to the dial 20 so as to rotate together with the dial 20. In the present embodiment, the dial 20 and the inner 30 are constituted by separate members, but these may be integrally formed, or the dial 20 may be omitted. Further, in FIG. 2, FIG. 3 and FIG. 6, the dial 20 is omitted.

ダイアル２０は、回転操作のために把持される円筒状の被把持部２１と、この被把持部２１の前端側に形成された前端壁２２とを有する。被把持部２１は、その後端部に当該被把持部２１を前記回転軸方向と直交する径方向に貫通する開口部２１ａを有する。この開口部２１ａは、後述の突部３２ａと係合可能な形状を有する。前端壁２２は、被把持部２１の前端側を塞ぐ形状を有し、当該被把持部２１の前端とつながっている。 The dial 20 includes a cylindrical gripped portion 21 gripped for a rotating operation, and a front end wall 22 formed on the front end side of the gripped portion 21. The gripped portion 21 has an opening 21 a that penetrates the gripped portion 21 in the radial direction perpendicular to the rotational axis direction at the rear end portion. The opening 21a has a shape that can be engaged with a protrusion 32a described later. The front end wall 22 has a shape that closes the front end side of the gripped portion 21 and is connected to the front end of the gripped portion 21.

インナー３０は、ホルダー４０に保持される被保持壁３１と、この被保持壁３１の外側に形成された周壁３２と、被保持壁３１及び周壁３２の後端部に形成された底壁３３と、ホルダー４０と摺接する摺接部３４とを有する。図１及び図４に示すように、このインナー３０は、その中央に、後述の保持壁４１を挿通可能な形状の開口を有する。 The inner 30 includes a held wall 31 held by the holder 40, a peripheral wall 32 formed outside the held wall 31, and a bottom wall 33 formed at the rear end of the held wall 31 and the peripheral wall 32. And a sliding contact portion 34 that is in sliding contact with the holder 40. As shown in FIGS. 1 and 4, the inner 30 has an opening having a shape into which a holding wall 41 described later can be inserted at the center thereof.

被保持壁３１は、前記回転軸を取り囲む円筒状であり、その前端面に全周にわたって形成された凹凸部３１ａを有する。凹凸部３１ａは、被保持壁３１の周方向に沿って交互に配置された凹部３１ｂと凸部３１ｃとを有する。この凹凸部３１ａは、後述の撓み変形部４１ａ及び突起４２とともに、操作者が回転操作部材１０を回転操作した際に操作者にクリック感を付与するものである。本実施形態では、凹凸部３１ａは、前記回転軸方向に起伏する形状としている。また、図３に示すように、各凸部３１ｃの前端面は、それぞれ平坦であり、かつ、前記回転軸と直交している。 The held wall 31 has a cylindrical shape surrounding the rotating shaft, and has a concavo-convex portion 31a formed on the entire front end surface thereof. The concavo-convex portion 31 a has concave portions 31 b and convex portions 31 c that are alternately arranged along the circumferential direction of the held wall 31. The concavo-convex portion 31a, together with the later-described bending deformation portion 41a and the protrusion 42, imparts a click feeling to the operator when the operator rotates the rotary operation member 10. In the present embodiment, the concavo-convex portion 31a has a shape that undulates in the direction of the rotation axis. Moreover, as shown in FIG. 3, the front end surface of each convex part 31c is each flat, and is orthogonal to the said rotating shaft.

周壁３２は、被把持部２１に内嵌可能な形状を有する。本実施形態では、周壁３２は、被保持壁３１よりも一回り大きな径を有する円筒状としている。この周壁３２の外側面には、被把持部２１の開口部２１ａと係合する形状の突部３２ａが形成されている。この突部３２ａが被把持部２１の開口部２１ａと係合することにより、ダイアル２０とインナー３０とは互いに相対回転しないように結合される。 The peripheral wall 32 has a shape that can be fitted into the gripped portion 21. In the present embodiment, the peripheral wall 32 has a cylindrical shape having a diameter that is slightly larger than the held wall 31. On the outer surface of the peripheral wall 32, a protrusion 32 a having a shape that engages with the opening 21 a of the gripped portion 21 is formed. When the protrusion 32a is engaged with the opening 21a of the gripped portion 21, the dial 20 and the inner 30 are coupled so as not to rotate relative to each other.

底壁３３は、周壁３２の後端面から前記回転軸と直交する径方向の外側に向かって全周にわたって張り出す形状を有する。図４に示すように、この底壁３３は、その径方向の内端部が被保持壁３１の後端面とつながっており、前記径方向の内端部から外端部に至る途中の部位が周壁３２の後端面とつながっている。そして、底壁３３のうち周壁３２よりも前記径方向の外側の部位の前端面でダイアル２０の後端面を受ける。 The bottom wall 33 has a shape that projects from the rear end surface of the peripheral wall 32 over the entire circumference toward the outside in the radial direction perpendicular to the rotation axis. As shown in FIG. 4, the bottom wall 33 has a radially inner end connected to a rear end surface of the held wall 31, and a portion in the middle from the radially inner end to the outer end. It is connected to the rear end surface of the peripheral wall 32. Then, the rear end surface of the dial 20 is received by the front end surface of the portion of the bottom wall 33 outside the peripheral wall 32 in the radial direction.

摺接部３４は、ホルダー４０に対して接触しながら前記周方向に摺動する。この摺接部３４は、底壁３３の裏面から前記回転軸方向に沿って後端側に向かって伸びる形状を有する。この実施形態では、摺接部３４は円筒状としている。 The sliding contact portion 34 slides in the circumferential direction while being in contact with the holder 40. The sliding contact portion 34 has a shape extending from the back surface of the bottom wall 33 toward the rear end side along the rotation axis direction. In this embodiment, the sliding contact portion 34 has a cylindrical shape.

ホルダー４０は、当該ホルダー４０に対する回転操作部材１０の前記回転軸回りの相対回転を許容するようにこの回転操作部材１０を保持する。このホルダー４０は、被保持壁３１を保持する保持壁４１と、凹凸部３１ａと係合する形状の突起４２と、インナー３０の後端面を受けることにより回転操作部材１０を受ける回転操作部材受け部４３とを有する。 The holder 40 holds the rotation operation member 10 so as to allow relative rotation of the rotation operation member 10 around the rotation axis with respect to the holder 40. The holder 40 includes a holding wall 41 that holds the held wall 31, a protrusion 42 that is shaped to engage with the concavo-convex portion 31 a, and a rotation operation member receiving portion that receives the rotation operation member 10 by receiving the rear end surface of the inner 30. 43.

保持壁４１は、被保持壁３１よりも一回り小さな径を有する円筒状であり、被保持壁３１に内嵌される。これにより、保持壁４１は、回転操作部材１０が前記径方向に変位しないように当該回転操作部材１０を保持する。保持壁４１は、その前端側に、撓み変形部４１ａと一対のスリット４１ｂとを有する。一対のスリット４１ｂは、保持壁４１の前端から前記回転軸方向に沿って後端側に向かって伸びる形状を有するとともに、保持壁４１の周方向に沿って互いに離間する位置に形成されている。撓み変形部４１ａは、一対のスリット４１ｂ間に形成される。これにより、撓み変形部４１ａは、保持壁４１の他の部位に対して前記回転軸側（前記径方向の内側）に向かって撓み変形可能となっている。より具体的には、撓み変形部４１ａは、その前端部が前記径方向の内側に向かって変位することを許容するように撓み変形が可能となっている。 The holding wall 41 has a cylindrical shape having a diameter slightly smaller than that of the held wall 31 and is fitted into the held wall 31. Thereby, the holding wall 41 holds the rotation operation member 10 so that the rotation operation member 10 is not displaced in the radial direction. The holding wall 41 has a bending deformation portion 41a and a pair of slits 41b on the front end side thereof. The pair of slits 41 b have a shape extending from the front end of the holding wall 41 toward the rear end side along the rotation axis direction, and are formed at positions spaced from each other along the circumferential direction of the holding wall 41. The bending deformation part 41a is formed between the pair of slits 41b. Thereby, the bending deformation part 41a can be bent and deformed toward the rotating shaft side (the inner side in the radial direction) with respect to other portions of the holding wall 41. More specifically, the bending deformation portion 41a can be bent and deformed so as to allow the front end portion to be displaced toward the inside in the radial direction.

突起４２は、被保持壁３１の前端面と係合することにより、回転操作部材１０を回転操作部材受け部４３との間で前記回転軸方向の両側から挟み込む形状を有する。この突起４２は、保持壁４１が被保持壁３１に対して当該被保持壁３１の裏面側から挿入されることにより、当該被保持壁３１の前端と係合する。突起４２は、撓み変形部４１ａの外側面の前端部から前記径方向の外側に向かって突出する形状を有する。図４及び図５に示すように、突起４２は、凹部３１ｂに嵌まり込み可能な形状の嵌まり込み部４２ａと、回転操作部材１０がホルダー４０に対して前記回転軸方向に沿って前端側へ変位することを規制する規制部４２ｂとを有する。 The protrusion 42 has a shape that sandwiches the rotation operation member 10 from the rotation operation member receiving portion 43 from both sides in the rotation axis direction by engaging with the front end surface of the held wall 31. The protrusion 42 is engaged with the front end of the held wall 31 when the holding wall 41 is inserted into the held wall 31 from the back side of the held wall 31. The protrusion 42 has a shape that protrudes outward in the radial direction from the front end portion of the outer surface of the bending deformation portion 41a. As shown in FIGS. 4 and 5, the protrusion 42 has a fitting portion 42 a having a shape that can be fitted into the concave portion 31 b, and the rotation operation member 10 is on the front end side along the rotation axis direction with respect to the holder 40. And a restricting portion 42b for restricting displacement to the right.

嵌まり込み部４２ａは、被保持壁３１の各凹部３１ｂに嵌まり込むとともに、前記径方向の内側への変位を伴いながら凸部３１ｃを乗り越え可能な形状を有する。ここで、回転操作部材１０が回転操作された際、嵌まり込み部４２ａが凹部３１ｂから離脱するまで前記径方向の内側へ変位することを許容するように撓み変形部４１ａが撓み変形し、嵌まり込み部４２ａが凸部３１ｃを乗り越えたとき、この嵌まり込み部４２ａは、撓み変形部４１ａの弾性復帰力により外向きに付勢されることによって当該凸部３１ｃに隣接する凹部３１ｂに係合する。また、図５に示すように、この嵌まり込み部４２ａは、回転操作部材１０の回転方向（周方向）の両端にそれぞれ形成された湾曲面を有する。この湾曲面は、前記回転方向の端部から前記回転方向の中央に向かうにしたがって前記径方向の外側に向かって突出し、かつ、その突出率が次第に小さくなる形状を有する。本実施形態では、この湾曲面を球面としている。 The fitting portion 42a has a shape that fits into each concave portion 31b of the held wall 31 and can get over the convex portion 31c while being displaced inward in the radial direction. Here, when the rotation operation member 10 is rotated, the bending deformation portion 41a is bent and deformed so as to allow the fitting portion 42a to be displaced inward in the radial direction until the fitting portion 42a is detached from the recess 31b. When the fitting portion 42a gets over the convex portion 31c, the fitting portion 42a is urged outward by the elastic return force of the bending deformation portion 41a to engage with the concave portion 31b adjacent to the convex portion 31c. Match. Further, as shown in FIG. 5, the fitting portion 42 a has curved surfaces respectively formed at both ends in the rotation direction (circumferential direction) of the rotation operation member 10. The curved surface has a shape that protrudes outward in the radial direction from the end in the rotation direction toward the center in the rotation direction, and the protrusion rate gradually decreases. In the present embodiment, this curved surface is a spherical surface.

規制部４２ｂは、被保持壁３１の前端面と接触可能な形状を有する。この規制部４２ｂは、嵌まり込み部４２ａの前端とつながっているとともに、撓み変形部４１ａの外側面における前端部から前記径方向の外側に向かって嵌まり込み部４２ａよりもさらに突出する形状を有する。具体的には、図２、図６、図７等に示すように、規制部４２ｂは、嵌まり込み部４２ａが凹部３１ｂに嵌まり込んでおり撓み変形部４１ａが変形していない状態において被保持壁３１の前端面（凸部３１ｃの表面）と接触するとともに、嵌まり込み部４２ａが凸部３１ｃの内周面上に乗り上げることを許容するように撓み変形部４１ａが撓み変形した状態においても被保持壁３１の前端面（凸部３１ｃの表面）に接触する形状を有する。なお、図７では、凹部３１ｂの位置を一点鎖線で示している。 The restricting portion 42 b has a shape that can contact the front end surface of the held wall 31. The restricting portion 42b is connected to the front end of the fitting portion 42a and has a shape that further protrudes from the front end portion on the outer side surface of the bending deformation portion 41a toward the outside in the radial direction than the fitting portion 42a. Have. Specifically, as shown in FIGS. 2, 6, 7, and the like, the restricting portion 42 b is covered in a state where the fitting portion 42 a is fitted in the concave portion 31 b and the bending deformation portion 41 a is not deformed. In a state where the bending deformation portion 41a is bent and deformed so as to contact the front end surface (surface of the convex portion 31c) of the holding wall 31 and allow the fitting portion 42a to run on the inner peripheral surface of the convex portion 31c. Also has a shape in contact with the front end surface of the held wall 31 (the surface of the convex portion 31c). In FIG. 7, the position of the recess 31b is indicated by a one-dot chain line.

本実施形態では、撓み変形部４１ａ、一対のスリット４１ｂ、及び突起４２は、保持壁４１の周方向に沿って９０度間隔で４箇所に形成している。ただし、これらの撓み変形部４１ａ、一対のスリット４１ｂ、及び突起４２は、保持壁４１の前端側の少なくとも一箇所に形成されればよい。 In the present embodiment, the bending deformation portion 41 a, the pair of slits 41 b, and the protrusions 42 are formed at four locations at intervals of 90 degrees along the circumferential direction of the holding wall 41. However, these bending deformation parts 41 a, the pair of slits 41 b, and the protrusions 42 may be formed in at least one place on the front end side of the holding wall 41.

回転操作部材受け部４３は、保持壁４１の後端部から前記回転軸と直交する径方向の外側に向かって全周にわたって張り出す形状を有する。図４に示すように、この回転操作部材受け部４３は、その前端面で摺接部３４の後端面を受ける。よって、回転操作部材１０が回転操作されたとき、摺接部３４は回転操作部材受け部４３の前端面に接触しながら当該回転操作部材受け部４３上を回転操作部材１０の回転方向（前記周方向）に摺動する。 The rotation operation member receiving portion 43 has a shape that protrudes from the rear end portion of the holding wall 41 over the entire circumference toward the outside in the radial direction orthogonal to the rotation axis. As shown in FIG. 4, the rotation operation member receiving portion 43 receives the rear end surface of the sliding contact portion 34 at the front end surface thereof. Therefore, when the rotation operation member 10 is rotated, the sliding contact portion 34 is in contact with the front end surface of the rotation operation member receiving portion 43 and moves on the rotation operation member receiving portion 43 in the rotation direction (the circumferential direction). Direction).

次に、この回転操作装置の組立工程を説明する。本実施形態の組立工程は、ダイアル２０とインナー３０とを接続することにより回転操作部材１０を組み立てる第一工程と、インナー３０とホルダー４０とを接続する第二工程とを含む。なお、第一工程と第二工程とは、その実施の順序を問わない。つまり、第一工程の後に第二工程が実施されても、あるいはその逆の順で実施されてもよく、さらには、両工程が同時に実施されてもよい。 Next, the assembly process of this rotary operation device will be described. The assembly process of the present embodiment includes a first process of assembling the rotary operation member 10 by connecting the dial 20 and the inner 30 and a second process of connecting the inner 30 and the holder 40. In addition, the 1st process and the 2nd process do not ask | require the order of the implementation. That is, the second step may be performed after the first step, or may be performed in the reverse order, and both steps may be performed simultaneously.

第一工程では、インナー３０の突部３２ａとダイアルの開口部２１ａとが係合するように、周壁３２を被把持部２１に内嵌する。 In the first step, the peripheral wall 32 is fitted into the grasped portion 21 so that the protrusion 32a of the inner 30 and the opening 21a of the dial are engaged.

第二工程では、インナー３０の被保持壁３１がホルダー４０の保持壁４１に保持されるようにこの被保持壁３１を保持壁４１に外嵌する。このとき、突起４２が被保持壁３１の内周面により前記径方向の内側に向かって押されることによって撓み変形部４１ａが撓み変形し、ホルダー４０の挿入完了時に、撓み変形部４１ａがその弾性により中立位置に復帰することにより嵌まり込み部４２ａが凹部３１ｂに嵌まり込む。これにより、回転操作部材１０は、突起４２と回転操作部材受け部４３との間に挟持される。 In the second step, the held wall 31 is externally fitted to the holding wall 41 so that the held wall 31 of the inner 30 is held by the holding wall 41 of the holder 40. At this time, the protrusion 42 is pushed inward in the radial direction by the inner peripheral surface of the held wall 31 to bend and deform the bending deformation portion 41a. When the insertion of the holder 40 is completed, the bending deformation portion 41a is elastically deformed. Thus, the fitting portion 42a is fitted into the recess 31b by returning to the neutral position. Thereby, the rotation operation member 10 is sandwiched between the protrusion 42 and the rotation operation member receiving portion 43.

続いて、本実施形態の回転操作装置の動作を説明する。 Next, the operation of the rotary operation device of this embodiment will be described.

ダイアル２０の被把持部２１を把持して当該ダイアル２０を回転操作すると、このダイアル２０とともにインナー３０が共回りする。なお、この回転操作部材１０の回転操作は、図示しない回転検出器によって検出される。 When the gripped portion 21 of the dial 20 is gripped and the dial 20 is rotated, the inner 30 rotates together with the dial 20. The rotation operation of the rotation operation member 10 is detected by a rotation detector (not shown).

このときの凹凸部３１ａと撓み変形部４１ａ及び突起４２との関係を、図２、図３、図６及び図７を参照しながら説明する。図２及び図３は、突起４２の嵌まり込み部４２ａが凹凸部３１ａの凹部３１ｂに嵌まり込んだ状態を示す。この状態では撓み変形部４１ａは変形しておらず、また、規制部４２ｂが被保持壁３１の前端面に接触している。 The relationship between the concavo-convex portion 31a, the bending deformation portion 41a, and the protrusion 42 at this time will be described with reference to FIGS. 2, 3, 6, and 7. FIG. 2 and 3 show a state where the fitting portion 42a of the protrusion 42 is fitted into the concave portion 31b of the concave and convex portion 31a. In this state, the bending deformation portion 41 a is not deformed, and the restricting portion 42 b is in contact with the front end surface of the held wall 31.

この状態から回転操作部材１０を回転操作すると、嵌まり込み部４２ａが凹部３１ｂから離脱して凸部３１ｃに乗り上げるまでは、撓み変形部４１ａがその変形度を増大させながら当該嵌まり込み部４２ａが前記径方向の内側に向かって変位する。これにより嵌まり込み部４２ａは凸部３１ｃの内周面上に乗り上げるが、この状態においても、規制部４２ｂは被保持壁３１の前端面に接触している（図６及び図７）。その後、嵌まり込み部４２ａが凸部３１ｃに乗り上げてから当該凸部３１ｃを乗り越えるまでは、この嵌まり込み部４２ａは撓み変形部４１ａの弾性復帰力による前記径方向の外側に向かう付勢力を受けることにより、当該凸部３１ｃの内周面に圧接されながら当該内周面上を前記周方向に摺動する。そして、嵌まり込み部４２ａが当該凸部３１ｃを乗り越えたとき、この嵌まり込み部４２ａは前記付勢力により当該凸部３１ｃに隣接する凹部３１ｂに係合する。 When the rotary operation member 10 is rotated from this state, until the fitting portion 42a is detached from the concave portion 31b and rides on the convex portion 31c, the bending deformation portion 41a increases the degree of deformation of the fitting portion 42a. Is displaced toward the inside in the radial direction. As a result, the fitting portion 42a rides on the inner peripheral surface of the convex portion 31c. Even in this state, the restricting portion 42b is in contact with the front end surface of the held wall 31 (FIGS. 6 and 7). Thereafter, from when the fitting portion 42a rides on the convex portion 31c until it gets over the convex portion 31c, the fitting portion 42a exerts an urging force toward the outside in the radial direction by the elastic return force of the bending deformation portion 41a. By receiving, it slides on the inner peripheral surface in the circumferential direction while being pressed against the inner peripheral surface of the convex portion 31c. And when the fitting part 42a gets over the said convex part 31c, this fitting part 42a engages with the recessed part 31b adjacent to the said convex part 31c with the said urging | biasing force.

ここで、回転操作部材１０の回転操作時には、嵌まり込み部４２ａが凹部３１ｂから離脱して凸部３１ｃに乗り上げるまでは、当該凹部３１ｂの前記周方向の部位と当接する嵌まり込み部４２ａを前記径方向の内側に向かって変位させるための操作抵抗が発生する一方、この嵌まり込み部４２ａが凸部３１ｃに乗り上げてから当該凸部３１ｃと隣接する凹部３１ｂに係合するまでの間は、嵌まり込み部４２ａは前記周方向からの抵抗を受けないので、当該嵌まり込み部４２ａが凸部３１ｃに乗り上げるときに比べて発生する操作抵抗は小さくなる。そして、当該嵌まり込み部４２ａが凸部３１ｃと隣接する凹部３１ｂに係合したとき、操作者は再び当該嵌まり込み部４２ａを凸部３１ｃに乗り上げさせるために必要な操作抵抗を感じる。この操作抵抗が操作者にクリック感として伝わる。よって、操作者は、回転操作部材１０の回転操作に伴って、繰り返し前記クリック感を感じることができる。 Here, during the rotation operation of the rotation operation member 10, until the fitting portion 42a is detached from the concave portion 31b and rides on the convex portion 31c, the fitting portion 42a that contacts the circumferential portion of the concave portion 31b is used. While an operation resistance for displacing toward the inside in the radial direction is generated, a period from when the fitting portion 42a rides on the convex portion 31c until it engages with the concave portion 31b adjacent to the convex portion 31c. Since the fitting portion 42a does not receive resistance from the circumferential direction, the operation resistance generated is smaller than when the fitting portion 42a rides on the convex portion 31c. And when the said fitting part 42a engages with the recessed part 31b adjacent to the convex part 31c, an operator feels the operation resistance required in order to make the said fitting part 42a ride on the convex part 31c again. This operation resistance is transmitted to the operator as a click feeling. Therefore, the operator can repeatedly feel the click feeling as the rotary operation member 10 is rotated.

このように、本実施形態の回転操作装置は、回転操作部材受け部４３との間で回転操作部材１０を前記回転軸方向の両側から挟み込むための突起４２を、クリック感を発生させるための構造として兼用したので、クリック感を発生させるための専用の部材、すなわち、回転操作部材１０やホルダー４０とは別体の弾性部材が不要となり構造が簡素化される。具体的には、被保持壁３１の前端面に凹凸部３１ａを設け、かつ、ホルダー４０の保持壁４１に撓み変形部４１ａ及び突起４２を設けるとともに、この突起４２を凹凸部３１ａの凹部３１ｂに係合可能な形状とすることにより、当該突起４２を、回転操作部材１０の回転操作時に前記径方向の内側に向かう変位を繰り返しながら各凹部３１ｂに順次係合させる構造とした。この突起４２の凹部３１ｂへの係合時に操作者はクリック感を感じるので、前記クリック感を発生させるための専用の部材専用の部材が不要となる。 As described above, the rotation operation device according to the present embodiment has a structure for generating a click feeling on the protrusion 42 for sandwiching the rotation operation member 10 from both sides in the rotation axis direction with the rotation operation member receiving portion 43. Therefore, a dedicated member for generating a click feeling, that is, an elastic member separate from the rotation operation member 10 and the holder 40 is not required, and the structure is simplified. Specifically, the uneven portion 31a is provided on the front end surface of the held wall 31, and the bending deformation portion 41a and the protrusion 42 are provided on the holding wall 41 of the holder 40, and the protrusion 42 is formed on the concave portion 31b of the uneven portion 31a. By adopting a shape that can be engaged, the protrusion 42 is configured to be sequentially engaged with the recesses 31b while repeating the displacement toward the inside in the radial direction when the rotation operation member 10 is rotated. Since the operator feels a click feeling when the protrusion 42 is engaged with the recess 31b, a dedicated member for generating the click feeling becomes unnecessary.

また、規制部４２ｂは、嵌まり込み部４２ａが凹部３１ｂと係合している状態（図２及び図３）に加え、嵌まり込み部４２ａが凸部３１ｃに乗り上げることを許容するように撓み変形部４１ａが撓み変形した状態（図６及び図７）においても被保持壁３１の前端面に接触するので、回転操作部材１０がホルダー４０に対してどのような回転角度となる場合であっても、当該回転操作部材１０がホルダー４０に対して前記回転軸方向に沿って前端側へ変位することが規制される。 In addition to the state where the fitting portion 42a is engaged with the recess 31b (FIGS. 2 and 3), the restricting portion 42b bends to allow the fitting portion 42a to ride on the convex portion 31c. Even when the deformed portion 41a is bent and deformed (FIGS. 6 and 7), the rotation operation member 10 is in any rotation angle with respect to the holder 40 because it contacts the front end surface of the held wall 31. In addition, the rotation operation member 10 is restricted from being displaced toward the front end side along the rotation axis direction with respect to the holder 40.

さらに、嵌まり込み部４２ａは、前記周方向の端部から前記周方向の中央に向かうにしたがって前記径方向の外側に向かって突出し、かつ、その突出率が次第に小さくなる形状の湾曲面を有するので、操作者に伝わるクリック感がより明瞭になる。具体的には、回転操作部材１０を回転操作する際の操作力は、嵌まり込み部４２ａを凹部３１ｂから離脱させるときに最大となるので、嵌まり込み部４２ａが凸部３１ｃを乗り越えて当該凸部３１ｃに隣接する凹部３１ｂに係合したときに操作者の感じる操作抵抗が最大となる。よって、操作者に明瞭なクリック感が伝わる。 Further, the fitting portion 42a has a curved surface that protrudes toward the outer side in the radial direction from the end in the circumferential direction toward the center in the circumferential direction, and has a shape in which the protruding rate gradually decreases. Therefore, the click feeling transmitted to the operator becomes clearer. Specifically, since the operating force when rotating the rotary operation member 10 is maximized when the fitting portion 42a is detached from the concave portion 31b, the fitting portion 42a gets over the convex portion 31c and The operating resistance felt by the operator when engaged with the concave portion 31b adjacent to the convex portion 31c is maximized. Therefore, a clear click feeling is transmitted to the operator.

なお、今回開示された実施形態は、すべての点で例示であって制限的なものではないと考えられるべきである。本発明の範囲は、上記した実施形態の説明ではなく特許請求の範囲によって示され、さらに特許請求の範囲と均等の意味および範囲内でのすべての変更が含まれる。 The embodiment disclosed this time should be considered as illustrative in all points and not restrictive. The scope of the present invention is shown not by the above description of the embodiments but by the scope of claims for patent, and further includes all modifications within the meaning and scope equivalent to the scope of claims for patent.

例えば、本実施形態では、凹凸部３１ａが、被保持壁３１の前端面に前記回転軸方向に起伏するように形成された例について示したが、この凹凸部３１ａは、被保持壁３１の内周面に前記周方向に全周にわたって形成されてもよい。すなわち、凹部が被保持壁３１の内周面から前記径方向の外側に向かって窪む形状とされてもよい。この場合、この凹凸部は、被保持壁３１の前端面よりも後端側に位置するように形成することもできる。 For example, in the present embodiment, an example in which the uneven portion 31 a is formed on the front end surface of the held wall 31 so as to undulate in the rotation axis direction has been described. You may form in a surrounding surface over the perimeter in the said circumferential direction. That is, the concave portion may have a shape that is recessed from the inner peripheral surface of the held wall 31 toward the outer side in the radial direction. In this case, the concavo-convex portion can be formed so as to be located on the rear end side with respect to the front end surface of the held wall 31.

また、上記実施形態では、嵌まり込み部４２ａが湾曲面を有する例について示したが、嵌まり込み部４２ａがこの湾曲面を有さない形状、例えば、前記周方向の両端から前記周方向の中央に向かって一定の突出率で突出する傾斜面を有する形状であってもよい。 Further, in the above-described embodiment, an example in which the fitting portion 42a has a curved surface has been described. However, the shape in which the fitting portion 42a does not have the curved surface, for example, the circumferential direction from both ends in the circumferential direction. The shape which has the inclined surface which protrudes with a fixed protrusion rate toward the center may be sufficient.

また、回転操作部材１０が回転操作されたときの嵌まり込み部４２ａの凹部３１ｂからの離脱を容易にするため、被保持壁３１の前記周方向における凹部３１ｂと凸部３１ｃとの境界を面取りしてもよい。 Further, in order to facilitate removal of the fitting portion 42a from the concave portion 31b when the rotary operation member 10 is rotated, the boundary between the concave portion 31b and the convex portion 31c in the circumferential direction of the held wall 31 is chamfered. May be.
