It is. 2 is a cross-sectional view taken along line AA of the locking device 10 shown in FIG.

開閉部材１２は、実際には２枚の板状部材を貼り合わせて、その内部の空間にロック装置１０を収容するが、図１（ｂ）はロック装置１０を覆う開閉部材１２の裏側の内側部材を省いて図示している。   The opening / closing member 12 actually has two plate-like members bonded together and accommodates the locking device 10 in the space inside thereof. FIG. 1B shows the inside of the back side of the opening / closing member 12 covering the locking device 10. It is shown with the members omitted.

開閉部材１２は、たとえば車両のグローブボックス用の蓋部材であり、外側部材と内側部材により構成される。グローブボックスはインストルメントパネルに設けられた収納空間である凹所を有する固定部材であり、開閉部材１２は、グローブボックスに回動可能に取り付けられ、凹所の開口部を開閉する。開閉部材１２の閉状態で、外側部材は助手席の正面に露出し、内側部材は凹所の内部に位置する。なお、開閉部材に収納部を設けてグローブボックスそのものを開閉部材としてよく、クローブボックスの回転によりクローブボックスの収納空間を開口させてよい。   The opening / closing member 12 is a lid member for a glove box of a vehicle, for example, and includes an outer member and an inner member. The glove box is a fixing member having a recess which is a storage space provided in the instrument panel, and the opening / closing member 12 is rotatably attached to the glove box and opens and closes the opening of the recess. When the opening / closing member 12 is closed, the outer member is exposed in front of the passenger seat, and the inner member is located inside the recess. The opening / closing member may be provided with a storage portion, and the glove box itself may be used as the opening / closing member, and the storage space of the clove box may be opened by rotation of the clove box.

開閉部材１２には、ロック装置１０を取り付けるための取付口１２ａが形成される。開閉部材１２に取り付けられたロック装置１０は、グローブボックスの開口部に対して開閉部材１２をロック状態にして閉状態に保持する。実施例のロック装置１０は、操作部材２０を開閉部材の幅方向に操作可能とするサイド式のロック装置である。   The opening / closing member 12 is formed with an attachment port 12 a for attaching the locking device 10. The locking device 10 attached to the opening / closing member 12 locks the opening / closing member 12 with respect to the opening of the glove box and holds it in the closed state. The locking device 10 according to the embodiment is a side-type locking device that enables the operation member 20 to be operated in the width direction of the opening / closing member.

ロック装置１０は、操作部材２０、ベース部材２２、ロータ部材２４、第１バネ部材２６、第２バネ部材２８、クッション３０および不図示の一対のロックバーを備える。   The lock device 10 includes an operation member 20, a base member 22, a rotor member 24, a first spring member 26, a second spring member 28, a cushion 30, and a pair of lock bars (not shown).

ロック装置１０は、開閉部材１２の外側部材と内側部材の間に画成される収容空間に設けられる。ベース部材２２は、開閉部材１２の取付口１２ａに固定される。操作部材２０は、ベース部材２２に回転可能に支持される。図１（ａ）に示すように取付口１２ａの表側に操作部材２０が露出する。ユーザは窪み部１２ｂから操作部材２０の裏側へ指を挿入し、操作部材２０を引くことでロック解除をする。   The locking device 10 is provided in an accommodation space defined between the outer member and the inner member of the opening / closing member 12. The base member 22 is fixed to the attachment port 12 a of the opening / closing member 12. The operation member 20 is rotatably supported by the base member 22. As shown in FIG. 1A, the operation member 20 is exposed on the front side of the attachment port 12a. The user releases the lock by inserting a finger into the back side of the operation member 20 from the recess 12 b and pulling the operation member 20.

図２に示すように開閉部材１２の内面にネジ用孔部１２ｄが柱状に立設される。ネジ用孔部１２ｄに連なって支持部１２ｅが立設される。支持部１２ｅは、ネジ用孔部１２ｄを支持し、ベース部材２２の位置決めとして機能する。ネジ用孔部１２ｄはねじ切られてもよく、ねじ切られてなくてもよいが、少なくともネジ３２に螺合する。   As shown in FIG. 2, a screw hole 12 d is erected in a columnar shape on the inner surface of the opening / closing member 12. A support portion 12e is erected in succession to the screw hole portion 12d. The support portion 12 e supports the screw hole portion 12 d and functions as positioning of the base member 22. The screw hole 12d may be threaded or not threaded, but is screwed into at least the screw 32.

ロータ部材２４は、ベース部材２２に回転可能に支持され、ロータ部材２４の一対の突起部４８が第１ロックバーおよび第２ロックバー（これらを区別しない場合「ロックバー」という）にそれぞれ連結する。ユーザの操作力は、操作部材２０の伝達部３６から図１（ｂ）に示す第１ロックバーへ、第１ロックバーからロータ部材２４へ、ロータ部材２４から第２ロックバーへと伝達される。ロータ部材２４は、操作部材２０の回転に応じて回転する。ロックバーは、ロータ部材２４の回転に連動して長手方向に進退する。ロックバーは、操作部材２０の回転に連動して固定部材のロック孔に係脱、すなわち係合したり係合解除することが可能である。   The rotor member 24 is rotatably supported by the base member 22, and a pair of protrusions 48 of the rotor member 24 are connected to a first lock bar and a second lock bar (referred to as “lock bar” if they are not distinguished from each other). . The operation force of the user is transmitted from the transmission portion 36 of the operation member 20 to the first lock bar shown in FIG. 1B, from the first lock bar to the rotor member 24, and from the rotor member 24 to the second lock bar. . The rotor member 24 rotates according to the rotation of the operation member 20. The lock bar advances and retracts in the longitudinal direction in conjunction with the rotation of the rotor member 24. The lock bar can be engaged with and disengaged from the lock hole of the fixed member in conjunction with the rotation of the operation member 20, that is, can be engaged or disengaged.

ユーザが操作部材２０を操作すると第１ロックバーを介してロータ部材２４が回転し、ロックバーはロータ部材２４の回転に応じて、固定部材であるグローブボックスに形成された第１ロック孔および第２ロック孔にそれぞれ出入りする。ロックバーの先端部がグローブボックスのロック孔に入ると開閉部材がロック状態となり、ロックバーがそのロック孔から出ると開閉部材が非ロック状態となる。   When the user operates the operation member 20, the rotor member 24 rotates through the first lock bar, and the lock bar rotates according to the rotation of the rotor member 24, and the first lock hole and the first lock hole formed in the glove box as the fixing member 2 Enter and exit the lock holes respectively. When the tip of the lock bar enters the lock hole of the glove box, the open / close member is locked, and when the lock bar comes out of the lock hole, the open / close member is unlocked.

第１バネ部材２６は、ロータ部材２４を付勢して、ロックバーがロック孔に入るロック方向に付勢する。第２バネ部材２８は、操作部材２０を閉状態に付勢する。クッション３０は、ゴム材料で形成され、操作部材２０を閉じたときの衝撃を緩和する。   The first spring member 26 biases the rotor member 24 and biases the lock bar in the locking direction where the lock bar enters the lock hole. The second spring member 28 biases the operation member 20 to the closed state. The cushion 30 is formed of a rubber material and relieves an impact when the operation member 20 is closed.

操作部材２０は、ユーザに操作される操作部３４と、挿通部３８に挿通される伝達部３６を有する。伝達部３６は、操作部材２０の裏面から立設して、ロックバーに接触して操作部材２０への操作力をロックバーに伝達する。伝達部３６は、操作部材２０の開き方向の操作によってロックバーを移動させて非ロック状態にさせる。   The operation member 20 includes an operation unit 34 operated by a user and a transmission unit 36 inserted through the insertion unit 38. The transmission unit 36 is erected from the back surface of the operation member 20, contacts the lock bar, and transmits the operation force to the operation member 20 to the lock bar. The transmission unit 36 moves the lock bar by the operation in the opening direction of the operation member 20 to bring it into the unlocked state.

ベース部材２２は、挿通部３８、取付部４０および係止部４２を有する。挿通部３８は、伝達部３６を内側に出させるための孔である。係止部４２は、鉤状に形成され、開閉部材１２の内面に引っ掛かり、ベース部材２２が開閉部材１２の外側に外れることを防ぐ。なお不図示の弾性爪部が、係止部４２の両側に撓み可能に形成され、窪み部１２ｂの外側の縁に係止し、ベース部材２２が開閉部材１２の内側に外れることを防ぐ。   The base member 22 has an insertion part 38, an attachment part 40, and a locking part 42. The insertion part 38 is a hole for letting out the transmission part 36 inside. The locking portion 42 is formed in a bowl shape and is caught on the inner surface of the opening / closing member 12 to prevent the base member 22 from coming off the opening / closing member 12. An elastic claw portion (not shown) is formed so as to be able to bend on both sides of the locking portion 42 and is locked to the outer edge of the recessed portion 12b, thereby preventing the base member 22 from coming off the inside of the opening / closing member 12.

取付部４０は、ネジ３２により開閉部材１２のネジ用孔部１２ｄに締結される。取付部４０は、係止部４２の反対側の端部に位置する。取付部４０は、ベース部材２２の側面から張り出すように板状に形成され、取付状態で開閉部材１２と略平行に延在する。   The attachment portion 40 is fastened to the screw hole portion 12 d of the opening / closing member 12 by a screw 32. The attachment portion 40 is located at the end portion on the opposite side of the locking portion 42. The attachment portion 40 is formed in a plate shape so as to protrude from the side surface of the base member 22, and extends substantially parallel to the opening / closing member 12 in the attached state.

取付部４０は、挿通孔４４および位置決め孔４６を有する。挿通孔４４は、ネジ用孔部１２ｄに位置合わせてして、ネジ３２を挿入される。位置決め孔４６は、支持部１２ｅを挿入される。位置決め孔４６に支持部１２ｅを挿入すれば、挿通孔４４とネジ用孔部１２ｄの位置が合うように構成される。   The attachment portion 40 has an insertion hole 44 and a positioning hole 46. The insertion hole 44 is inserted into the screw hole 12d in alignment with the screw hole 12d. The support hole 12e is inserted into the positioning hole 46. When the support portion 12e is inserted into the positioning hole 46, the insertion hole 44 and the screw hole portion 12d are configured to be aligned.

ロック装置１０は、係止部４２を取付口１２ａの縁に引っ掛け、係止部４２を支点としてロック装置１０を回転させて、取付部４０を着座面１２ｃに着座させるとともに位置決め孔４６に支持部１２ｅを受け入れて位置決めされる。次に、ロック装置１０は、ネジ３２を挿通孔４４およびネジ用孔部１２ｄに挿入して、ネジ３２およびネジ用孔部１２ｄの螺合により取付部４０を締結される。これにより、ロック装置１０が開閉部材１２の取付口１２ａに取り付けられる。   The locking device 10 hooks the locking portion 42 on the edge of the mounting opening 12a, rotates the locking device 10 with the locking portion 42 as a fulcrum, and seats the mounting portion 40 on the seating surface 12c and supports the positioning hole 46 with a support portion. 12e is received and positioned. Next, in the locking device 10, the screw 32 is inserted into the insertion hole 44 and the screw hole 12d, and the mounting portion 40 is fastened by screwing the screw 32 and the screw hole 12d. Thereby, the locking device 10 is attached to the attachment port 12 a of the opening / closing member 12.

ロック装置１０は、開閉部材１２に取り付ける取付部品であり、開閉部材１２はロック装置１０を取り付けられる被取付部品である。図２には取付部品をネジ３２により被取付部品に取り付けるための部品取付構造が示される。   The locking device 10 is an attachment component that is attached to the opening / closing member 12, and the opening / closing member 12 is an attached component to which the locking device 10 is attached. FIG. 2 shows a component mounting structure for mounting the mounting component to the mounted component with the screw 32.

図３は、比較技術の取付部１４０を開閉部材１２に締結した状態を説明するための図である。ネジ用孔部１１２ｄは、着座面１１２ｃの面直方向に対して交差している。着座面１１２ｃの面直方向は、着座面１１２ｃに垂直な方向である。着座面１１２ｃは平らに形成される。   FIG. 3 is a view for explaining a state in which the attachment part 140 of the comparative technique is fastened to the opening / closing member 12. The screw hole 112d intersects the perpendicular direction of the seating surface 112c. The perpendicular direction of the seating surface 112c is a direction perpendicular to the seating surface 112c. The seating surface 112c is formed flat.

開閉部材１２は、２つの金型を割る型抜き成形により製造される。開閉部材１２の種類によっては、金型の型抜き方向が異なり、図３に示すようにネジ用孔部１２ｄの中心軸が傾斜する場合がある。平板状の取付部１４０を着座面１１２ｃに着座させてネジ３２で締結すると、頭部３２ａの外周縁が取付部１４０の表面に当接する。   The opening / closing member 12 is manufactured by die-cutting that splits two molds. Depending on the type of the opening / closing member 12, the mold drawing direction is different, and the central axis of the screw hole 12d may be inclined as shown in FIG. When the flat mounting portion 140 is seated on the seating surface 112 c and fastened with the screw 32, the outer peripheral edge of the head portion 32 a comes into contact with the surface of the mounting portion 140.

ネジ３２の座面６０がネジ３２の中心軸から遠い位置で取付部１４０に当接すると、ネジ３２が取付部１４０から受けるモーメントが大きくなり、経時的にガタつくおそれがある。また、ネジ用孔部１２ｄの傾斜に応じて取付部１４０の形状を作り替えるとコストがかかる。そこで、実施例の部品取付構造では、ネジ用孔部１２ｄの傾斜角が異なっても安定して締結できる取付部４０を形成する。   When the seating surface 60 of the screw 32 contacts the mounting portion 140 at a position far from the central axis of the screw 32, the moment that the screw 32 receives from the mounting portion 140 increases, and there is a risk of rattling over time. Further, if the shape of the mounting portion 140 is reshaped according to the inclination of the screw hole portion 12d, it costs high. Therefore, in the component mounting structure of the embodiment, the mounting portion 40 that can be fastened stably even if the inclination angle of the screw hole portion 12d is different is formed.

図４は、取付部４０をネジ用孔部に締結した部品取付構造を示す。図４（ａ）では、ネジ用孔部１２ｄの中心軸が着座面１２ｃの面直方向と平行に形成されており、図４（ｂ）では、ネジ用孔部１１２ｄの中心軸が着座面１１２ｃの面直方向に交差して形成されている。   FIG. 4 shows a component mounting structure in which the mounting portion 40 is fastened to the screw hole. In FIG. 4A, the central axis of the screw hole 12d is formed parallel to the perpendicular direction of the seating surface 12c. In FIG. 4B, the central axis of the screw hole 112d is the seating surface 112c. Are formed so as to intersect in the direction perpendicular to the surface.

挿通孔４４の内周面は、裏面側から表面側に向かって拡径するように形成され、表面側の開口縁５４が裏面側の開口縁５５より大きくなるように形成されている。挿通孔４４は、ネジ用孔部１２ｄの孔径より大径に設けられる。これにより、挿通孔４４の中心軸に対してネジ３２の軸部７０を傾斜した状態で挿入できる。   The inner peripheral surface of the insertion hole 44 is formed so as to increase in diameter from the rear surface side toward the front surface side, and the opening edge 54 on the front surface side is formed to be larger than the opening edge 55 on the rear surface side. The insertion hole 44 is provided with a diameter larger than that of the screw hole 12d. Accordingly, the shaft portion 70 of the screw 32 can be inserted in an inclined state with respect to the central axis of the insertion hole 44.

取付部４０の表面５０には、挿通孔４４の表面５０側の開口縁５４から径方向外向きに下るように傾斜する周状斜面５６が形成される。周状斜面５６は、挿通孔４４の表面５０側の開口縁５４に向かって***するように傾斜し、円錐台状に形成される。周状斜面５６は、周方向に渡って環状に形成されるが、複数の斜面が周方向に離間して形成されてよく、周状に段差を有して形成されてよい。いずれにしても、異なる向きで挿入されたネジ３２に対して、その座面６０を周状斜面５６に当接可能に設けられる。周状斜面５６は、座面６０の外周縁６４を表面５０に当接させないように、周状斜面５６の傾斜角と高さが設定される。取付部４０の裏面５２は、挿通孔４４をネジ用孔部１２ｄに位置合わせした状態で着座面１２ｃに着座する。   A circumferential slope 56 is formed on the surface 50 of the mounting portion 40 so as to incline so as to descend radially outward from the opening edge 54 on the surface 50 side of the insertion hole 44. The circumferential inclined surface 56 is inclined so as to protrude toward the opening edge 54 on the surface 50 side of the insertion hole 44 and is formed in a truncated cone shape. The circumferential slope 56 is formed in an annular shape in the circumferential direction, but a plurality of slopes may be formed apart from each other in the circumferential direction, or may be formed with a step in the circumference. In any case, the seat surface 60 is provided to be able to contact the circumferential inclined surface 56 with respect to the screw 32 inserted in a different direction. The inclination angle and height of the circumferential inclined surface 56 are set so that the outer peripheral edge 64 of the seating surface 60 does not contact the surface 50. The back surface 52 of the mounting portion 40 is seated on the seating surface 12c in a state where the insertion hole 44 is aligned with the screw hole portion 12d.

図４（ａ）には、挿通孔４４の開口縁５４が全周に渡って座面６０に当接した状態を示す。挿通孔４４は、ネジ３２の軸部７０と隙間を有する。座面６０と着座面１２ｃで取付部４０を挟み込んで、取付部４０が開閉部材１２に取り付けられる。座面６０は、頭部３２ａの裏側に平らに形成される。   FIG. 4A shows a state in which the opening edge 54 of the insertion hole 44 is in contact with the seating surface 60 over the entire circumference. The insertion hole 44 has a gap with the shaft portion 70 of the screw 32. The attachment portion 40 is attached to the opening / closing member 12 by sandwiching the attachment portion 40 between the seat surface 60 and the seating surface 12c. The seat surface 60 is formed flat on the back side of the head portion 32a.

図４（ｂ）には、着座面１１２ｃの面直方向に対して中心軸が交差しているネジ用孔部１１２ｄにネジ３２を螺合して取付部４０を締結した状態を示す。挿通孔４４の中心軸に対してネジ３２の中心軸を交差した状態でネジ３２をネジ用孔部１１２ｄに螺合する。取付部４０の表面５０は、座面６０の外周縁６４には当接しないように座面６０に当接する。つまり、取付部４０の表面５０は、座面６０の外周縁６４より径方向内側の座面６０に当接する。これにより、座面６０がネジ３２の中心軸から近い位置で取付部４０に当接するため、ネジ３２が取付部４０から受けるモーメントが小さくなり、経時的なガタつきを抑えることができる。   FIG. 4B shows a state in which the mounting portion 40 is fastened by screwing the screw 32 into the screw hole portion 112d whose central axis intersects with the perpendicular direction of the seating surface 112c. The screw 32 is screwed into the screw hole 112d in a state where the central axis of the screw 32 intersects the central axis of the insertion hole 44. The surface 50 of the mounting portion 40 contacts the seat surface 60 so as not to contact the outer peripheral edge 64 of the seat surface 60. That is, the surface 50 of the mounting portion 40 abuts on the seat surface 60 radially inward from the outer peripheral edge 64 of the seat surface 60. Thereby, since the seat surface 60 contacts the attachment portion 40 at a position close to the central axis of the screw 32, the moment that the screw 32 receives from the attachment portion 40 is reduced, and the backlash with time can be suppressed.

取付部４０の表面５０は、ネジ３２の座面６０と周方向において部分的に当接し、座面６０の内周縁６２および外周縁６４の中央位置６６より径方向内側の領域６８に当接する。つまり、挿通孔４４の開口縁５４が座面６０の径方向内側の領域６８に当接する。これにより、頭部３２ａの外周縁６４が取付部４０の表面５０に当接することを避け、座面６０がネジ３２の中心軸から近い位置で取付部４０に当接する。   The surface 50 of the mounting portion 40 partially abuts with the seat surface 60 of the screw 32 in the circumferential direction, and abuts against a region 68 radially inward from the center position 66 of the inner peripheral edge 62 and the outer peripheral edge 64 of the seat surface 60. That is, the opening edge 54 of the insertion hole 44 abuts on the radially inner region 68 of the seat surface 60. Accordingly, the outer peripheral edge 64 of the head portion 32 a is prevented from coming into contact with the surface 50 of the attachment portion 40, and the seat surface 60 is brought into contact with the attachment portion 40 at a position near the central axis of the screw 32.

図５は、取付部４０の周状斜面５６の形状について説明するための図である。取付部の表面５０に形成される周状斜面５６の高さをＨとする。ネジ３２の座面６０の外径をＤとする。挿通孔４４の開口縁５４の直径をｄとする。周状斜面５６を除く取付部４０の板厚をｔとする。着座面１１２ｃの面直方向７１に対するネジ用孔部１１２ｄの中心軸７２の傾斜角をθとする。傾斜角θは最大で２０度ほどである。着座面１１２ｃの面直方向７１は、挿通孔４４の中心軸に相当する。   FIG. 5 is a diagram for explaining the shape of the circumferential inclined surface 56 of the mounting portion 40. Let H be the height of the circumferential slope 56 formed on the surface 50 of the mounting portion. The outer diameter of the seating surface 60 of the screw 32 is D. The diameter of the opening edge 54 of the insertion hole 44 is d. The thickness of the mounting portion 40 excluding the circumferential slope 56 is assumed to be t. An inclination angle of the central axis 72 of the screw hole 112d with respect to the perpendicular direction 71 of the seating surface 112c is defined as θ. The inclination angle θ is about 20 degrees at the maximum. The perpendicular direction 71 of the seating surface 112 c corresponds to the central axis of the insertion hole 44.

周状斜面５６の高さＨは、数式（１）を満たすように形成される。このように周状斜面５６の高さＨの下限値を設定することで、頭部３２ａの外周縁６４取付部４０の表面５０に当接しないように構成できる。
Ｈ＞（Ｄ／２−（ｄ／２−（Ｈ＋ｔ）ｔａｎθ）ｃｏｓθ）ｓｉｎθ ・・・（１）。 The height H of the circumferential slope 56 is formed so as to satisfy Expression (1). Thus, by setting the lower limit value of the height H of the circumferential slope 56, it can be configured not to contact the surface 50 of the outer peripheral edge 64 mounting portion 40 of the head portion 32a.
H> (D / 2− (d / 2− (H + t) tan θ) cos θ) sin θ (1).

数式（１）の導出について説明する。符号７４には、開口縁５４の位置での挿通孔４４の中心軸とネジ３２の中心軸とのずれ幅が示され、（Ｈ＋ｔ）ｔａｎθとなる。残りの幅７６は、ｄ／２−（Ｈ＋ｔ）ｔａｎθとなる。幅７６におけるネジ３２の中心軸に垂直成分７８は、（ｄ／２−（Ｈ＋ｔ）ｔａｎθ）ｃｏｓθとなる。   Derivation of Equation (1) will be described. Reference numeral 74 indicates a deviation width between the central axis of the insertion hole 44 and the central axis of the screw 32 at the position of the opening edge 54, which is (H + t) tan θ. The remaining width 76 is d / 2− (H + t) tan θ. A component 78 perpendicular to the central axis of the screw 32 at the width 76 is (d / 2− (H + t) tan θ) cos θ.

開口縁５４に当接したネジ３２の座面６０の位置から外周縁６４までの長さ８０は、Ｄ／２−（ｄ／２−（Ｈ＋ｔ）ｔａｎθ）ｃｏｓθとなる。長さ８０の面直方向７１の成分８２は、（Ｄ／２−（ｄ／２−（Ｈ＋ｔ）ｔａｎθ）ｃｏｓθ）ｓｉｎθとなる。成分８２より周状斜面５６が高ければ頭部３２ａの外周縁６４が表面５０に当接することを避けることができ、数式（１）に示す周状斜面５６の高さＨの下限値が導出される。周状斜面５６の高さＨは、低いほどコストが抑えられるため好ましいが、高さＨの上限値はネジ３２の軸部７０の長さによって設定される。   A length 80 from the position of the seating surface 60 of the screw 32 in contact with the opening edge 54 to the outer peripheral edge 64 is D / 2− (d / 2− (H + t) tan θ) cos θ. The component 82 of the length 80 in the perpendicular direction 71 is (D / 2− (d / 2− (H + t) tan θ) cos θ) sin θ. If the circumferential slope 56 is higher than the component 82, the outer peripheral edge 64 of the head 32a can be prevented from coming into contact with the surface 50, and the lower limit value of the height H of the circumferential slope 56 shown in Equation (1) is derived. The The lower the height H of the circumferential slope 56, the lower the cost, which is preferable. However, the upper limit of the height H is set by the length of the shaft portion 70 of the screw 32.

また、ネジ３２の軸部７０の外径８４をＤＮとすると、ネジ３２の座面６０の外径Ｄは、数式（２）を満たすように形成される。これにより、θがゼロであっても頭部３２ａが挿通孔４４を抜けることなく、ネジ３２で取付部４０を締結できる。
Ｄ／２＞（Ｈ＋ｔ）ｔａｎθ＋（ＤＮ／２）ｃｏｓθ ・・・（２） Further, when the outer diameter 84 of the shaft portion 70 of the screw 32 is DN, the outer diameter D of the seating surface 60 of the screw 32 is formed so as to satisfy Expression (2). Thereby, even if (theta) is zero, the attaching part 40 can be fastened with the screw | thread 32, without the head part 32a coming out of the insertion hole 44. FIG.
D / 2> (H + t) tan θ + (DN / 2) cos θ (2)
