Description

この発明は、自動販売機のポップアップ式のハンドル錠の破錠防止装置（以下単に破錠防止装置という）に係り、特に、例えば暴力的な破錠等の不正解錠を完全に防止でき、錠前としての安全性を高ると共に、作動が確実で、しかもコストダウンを図ることができる破錠防止装置に関する。   The present invention relates to a pop-up-type handle lock prevention device (hereinafter simply referred to as a lock prevention device) of a vending machine, and in particular, can completely prevent unauthorized unlocking such as violent unlocking. The present invention relates to a device for preventing tablet breakage, which can improve safety as well as reliably operate and can reduce costs.

自動販売機のハンドル錠の構造は、例えば後記特許文献１、２及び４に記載されていてそれ自体周知である。
特開平０９−１５１６３０号公報 特開２００２−０７０３８９ 特許第３９６３９８１号の特許公報 特開平０７−０７６９６１号公報 The structure of the handle lock of the vending machine is described in, for example, Patent Documents 1, 2, and 4 described below, and is well known per se.
JP 09-151630 A JP 2002-070389 A Patent No. 3963981 Japanese Patent Application Laid-Open No. 07-076961

しかしながら、ハンドル錠は、特許文献１に記載されているように、暴力的な手法によりシリンダ錠を抜かれると容易に破錠されてしまい、この場合、シリンダ錠を抜いた穴から工具等を差し入れ、或いは直接手指で操作することにより内部機構を操作すればハンドルをポップアップできるという不都合がある。   However, as described in Patent Document 1, the handle lock is easily broken when the cylinder lock is pulled out by a violent technique. In this case, a tool or the like is inserted through the hole from which the cylinder lock is pulled out. Alternatively, if the internal mechanism is operated by directly operating with fingers, the handle can be popped up.

これを防止するため、上記特許文献２に記載された扉の錠装置は、ハンドル錠の錠止機構に加え、所謂電気錠を併設し、この電気錠を解錠しないとハンドルがポップアップできないように構成されている。   In order to prevent this, the door locking device described in Patent Document 2 is provided with a so-called electric lock in addition to the locking mechanism of the handle lock so that the handle cannot be popped up unless the electric lock is unlocked. It is configured.

電気錠は、例えばテンキー等の暗証番号入力装置を破壊しても電気錠を解錠することができないので、これをハンドル錠に併設した場合、例えシリンダ錠をハンドルから抜いてもハンドルをポップアップさせることができず、したがってハンドル錠の錠前としての安全性が格段に向上する。   The electric lock cannot be unlocked even if the PIN code input device such as a numeric keypad is broken. For example, when this is attached to the handle lock, the handle pops up even if the cylinder lock is removed from the handle lock. Therefore, the safety of the handle lock is greatly improved.

しかしながら、上記特許文献２に記載された電気錠は、電磁アクチュエータとしてソレノイドを採用しているので、ソレノイド自体が比較的高価であることから破錠防止装置のコストダウンを図ることが困難である。   However, since the electric lock described in Patent Document 2 employs a solenoid as an electromagnetic actuator, it is difficult to reduce the cost of the lock prevention device because the solenoid itself is relatively expensive.

また、プランジャをコイルばねにより常時施錠方向に付勢している関係で、解錠方向にソレノイドを駆動するとき大電流を必要とするばかりでなく、ソレノイドへの通電を断つと施錠してしまうので、解錠時長時間通電しなければならず、制御回路が複雑である、等未だ改良の余地がある。   Also, because the plunger is always biased by the coil spring in the locking direction, not only does it require a large current when driving the solenoid in the unlocking direction, but it will lock if the solenoid is de-energized. There is still room for improvement, such as the need to energize for a long time during unlocking and the complicated control circuit.

本願発明は、出願人が開発した新規な作動装置を電磁アクチュエータとして採用することにより、破錠防止装置の構造を簡単にすると共に作動の確実性を向上させ、更に、コストダウンを図ることを目的としている。   The present invention aims to simplify the structure of the anti-breaking device, improve the reliability of the operation, and further reduce the cost by adopting the new actuator developed by the applicant as an electromagnetic actuator. It is said.

上記の目的を達成するため、請求項１に記載の発明は、一端が開口したカップ状で、シリンダ錠を開口端部に固定した筒部及び筒部の開口端縁に一体に形成された把手部よりなるハンドルと、ハンドルを突出入可能に収容する錠ケースと、ハンドルを突出位置に向け付勢させるために錠ケース内に設けた押しばねと、ハンドルを錠ケース内に没入した状態でこれを固定することができると共に、シリンダ錠を合鍵によって解錠した後、内筒を所定の方向に回動させることによりハンドルを解放するように構成されたラッチ部とを有するハンドル錠において、モータの回転出力軸に、横断面円形の棒状体である案内部材を同軸に装着し、この案内部材にらせん状の疎巻コイルばねを案内部材の長さ方向に移動可能に巻装すると共に、案内部材の外周面の長さ方向における中央部に、ばねのピッチ間隙を遊動できる単一の突起を突設し、上記疎巻コイルばねの両端を案内部材の半径方向における外方に延出させた作動装置を、上記錠ケースの外側に、かつ案内部材が錠ケースの中心軸に垂直になるような位置関係で配設し、一方、上記案内部材とほぼ平行なロックピースを案内部材の長さ方向に移動可能に案内すると共に、その錠ケースに対向する側の一端に形成した係合爪を、錠ケースを貫通して、ハンドルの筒部外周面に形成された錠止凹部に係合可能に臨ませ、他方、上記作動装置のばねの延出部分をロックピースに係合させ、モータを正、逆転させることにより、作動装置のばねを介してロックピースをハンドルの錠止凹部に係脱させるようにしたことを特徴とする。   In order to achieve the above-mentioned object, the invention described in claim 1 is a cup-like shape having an opening at one end, and a handle having a cylinder lock fixed to the opening end and a handle formed integrally with the opening edge of the tube. A handle comprising a handle, a lock case for receiving the handle in a projecting manner, a push spring provided in the lock case for biasing the handle toward the projecting position, and a handle immersed in the lock case. In the handle lock having the latch portion configured to release the handle by rotating the inner cylinder in a predetermined direction after unlocking the cylinder lock with the key, A guide member, which is a rod-shaped body having a circular cross section, is coaxially mounted on the rotation output shaft, and a helically wound coil spring is wound around the guide member so as to be movable in the length direction of the guide member. of An operating device in which a single protrusion capable of floating the pitch gap of the spring is provided at the center in the longitudinal direction of the peripheral surface, and both ends of the loosely wound coil spring are extended outward in the radial direction of the guide member. On the outside of the lock case and in a positional relationship such that the guide member is perpendicular to the central axis of the lock case, while a lock piece substantially parallel to the guide member is disposed in the length direction of the guide member. The engaging claw formed at one end on the side facing the lock case is guided through the lock case so as to be able to engage with a lock recess formed on the outer peripheral surface of the cylindrical portion of the handle. On the other hand, the extension part of the spring of the actuator is engaged with the lock piece, and the motor is rotated forward and backward so that the lock piece is engaged with and disengaged from the locking recess of the handle via the spring of the actuator. It is characterized by that.

上記のように構成されたこの発明による破錠防止装置は、電気錠の電磁アクチュエータとして例えば玩具用の直流モータを採用することができるので、作動装置の構造が簡単であることとも相俟て、破錠防止装置としてのコストダウンを図ることができる。   Since the anti-breaking device according to the present invention configured as described above can employ, for example, a DC motor for toys as an electromagnetic actuator for an electric lock, in combination with the simple structure of the operating device, Cost reduction as an anti-breaking device can be achieved.

また、モータの正転、逆転を電気錠の施錠、解錠に対応させると共に、施錠、解錠状態を維持するために通電を必要としないので、作動の確実性を期待することができる。   Further, since the forward and reverse rotations of the motor correspond to the locking and unlocking of the electric lock, and energization is not required to maintain the locked and unlocked state, the operation reliability can be expected.

更にまた、同じ理由により、モータの制御回路を簡単にでき、その分コストダウンを図ることができると共に、破錠防止装置としての信頼性を向上させることができる、等種々の効果を奏する。   Furthermore, for the same reason, the motor control circuit can be simplified, the cost can be reduced correspondingly, and the reliability as the anti-breaking device can be improved.

電気錠の電磁アクチュエータとして、正、逆転できるモータの回転出力軸に、横断面円形の棒状体である案内部材を同軸に装着し、この案内部材にらせん状の疎巻コイルばねを案内部材の長さ方向に移動可能に巻装すると共に、案内部材の外周面の長さ方向における中央部に、ばねのピッチ間隙を遊動できる単一の突起を突設し、上記疎巻コイルばねの両端を案内部材の半径方向における外方に延出させてロックピースに係合させた作動装置を採用したので、電気錠のコストダウン及び電気錠の錠前としての安全性の向上を図ることができるばかりでなく、破錠防止装置としての信頼性を向上させることができた。   As an electromagnetic actuator for an electric lock, a guide member, which is a rod-shaped body with a circular cross section, is coaxially mounted on the rotation output shaft of a motor that can be rotated forward and backward, and a helical, loosely wound coil spring is attached to the guide member. A single protrusion that can freely move the pitch gap of the spring is provided at the center of the outer circumferential surface of the guide member in the longitudinal direction so as to be movable in the vertical direction, and guides both ends of the loosely wound coil spring. Since the actuator that extends outward in the radial direction of the member and is engaged with the lock piece is adopted, not only can the cost of the electric lock be reduced and the safety as the lock of the electric lock can be improved. As a result, the reliability as an anti-breaking device could be improved.

以下、図面を参照してこの発明の実施例を説明する。
図１乃至図３において符号１はハンドルを示し、このハンドル１は、一端（図２で下端）が開口したカップ状の筒部２と、この筒部の開口端部に一体に形成された把手部３（図１及び図３参照）とを有してなる。 Embodiments of the present invention will be described below with reference to the drawings.
1 to 3, reference numeral 1 denotes a handle. The handle 1 has a cup-shaped tube portion 2 with one end (lower end in FIG. 2) opened, and a handle formed integrally with the open end portion of the tube portion. Part 3 (see FIGS. 1 and 3).

但し、図１乃至図３においては、（図３において鎖線で示すシリンダ錠４を除いて）筒部２の開口端部に固定されるシリンダ錠は、図面を明瞭にするため図示を省略してある。   However, in FIGS. 1 to 3, the cylinder lock fixed to the open end of the cylinder portion 2 (except for the cylinder lock 4 indicated by a chain line in FIG. 3) is omitted for the sake of clarity. is there.

また、上記ハンドルの筒部２は、図２乃至図４に示すように、付番しないスリット（図４参照の下端部参照）付のカップ錠の錠ケース５に、軸線方向（図３で左右方向）に移動可能に、換言すれば、図３に実線で示す没入位置から図３に鎖線で示す突出位置の間を移動可能に収容されている。   Further, as shown in FIGS. 2 to 4, the cylindrical portion 2 of the handle is placed in the axial direction (left and right in FIG. 3) on the lock case 5 of the cup lock with an unnumbered slit (see the lower end portion in FIG. 4). In other words, it is accommodated so as to be movable between an immersion position indicated by a solid line in FIG. 3 and a protruding position indicated by a chain line in FIG.

一方、上記錠ケース５は、取付ビス６、６（図２及び図３参照）により、その開口端外周部に形成された付番しない段部を取付枠の開口段部に呼び付けられるようにして、取付枠７に固定されている。   On the other hand, the above-mentioned lock case 5 is configured so that an unnumbered step formed on the outer peripheral portion of the opening end can be called to the opening step of the mounting frame by mounting screws 6 and 6 (see FIGS. 2 and 3). And fixed to the mounting frame 7.

また、ハンドル１を図３に実線で示す没入位置から鎖線で示す突出位置に向け付勢するため、錠ケース５の底部内面とハンドルの筒部２の底部外面との間に、断面が略凹字形のばね収納空間８が形成されている。   Further, in order to urge the handle 1 from the immersive position indicated by the solid line in FIG. 3 toward the protruding position indicated by the chain line, the cross section is substantially concave between the bottom inner surface of the lock case 5 and the bottom outer surface of the cylindrical portion 2 of the handle. A letter-shaped spring storage space 8 is formed.

そして、上記ばね収納空間８内には、全体の形状が台形の圧縮コイルばねとしての図示しない押しばねが弾装されていて、ハンドル１を図３に鎖線で示す位置に突出する方向に付勢している。   A pressing spring (not shown) as a trapezoidal compression coil spring having an overall shape trapped in the spring housing space 8 is urged in a direction in which the handle 1 protrudes to a position indicated by a chain line in FIG. is doing.

このハンドル錠のハンドル１は、図３に示すシリンダ錠の施錠状態では、上記押しばねの弾力にも拘らず図３に示すような没入位置、すなわち、筒部２が完全に錠ケース５内に収容され、かつ、把手部３の外表面が取付枠７のそれと同一表面になる位置にある。   In the locked state of the cylinder lock shown in FIG. 3, the handle 1 of this handle lock is in the immersion position as shown in FIG. 3, that is, the cylindrical portion 2 is completely in the lock case 5 regardless of the elasticity of the push spring. It is accommodated and is located at a position where the outer surface of the handle portion 3 is the same surface as that of the mounting frame 7.

上記シリンダ錠の施錠時ハンドル１を図２及び３に示す没入位置に保持し、シリンダ錠を解錠した後内筒を所定の方向に回動したときハンドル１を解放し、持って押しばねの弾力によりハンドル１を図３に鎖線で示す位置に迄突出させるため、ハンドル筒部の底部に図４に示すようなラッチ部９が設けられている。   When the cylinder lock is locked, the handle 1 is held in the retracted position shown in FIGS. 2 and 3, and after unlocking the cylinder lock, the handle 1 is released when the inner cylinder is rotated in a predetermined direction. In order to project the handle 1 to the position indicated by the chain line in FIG. 3 by elasticity, a latch portion 9 as shown in FIG. 4 is provided at the bottom of the handle tube portion.

図示の実施例におけるラッチ部９は、図４に示すように、相互に回り止めを施された状態で軸線方向（図４で紙面の厚さ方向）に相対移動可能に嵌合するハンドル筒部２及び錠ケース５の内端部（図３参照）を共通に貫通する断面Ｌ字形のデッドボルト１１により、シリンダ錠の施錠時ハンドル筒部２を錠ケース５に錠止する。   As shown in FIG. 4, the latch portion 9 in the illustrated embodiment is a handle tube portion that fits so as to be relatively movable in the axial direction (the thickness direction of the paper surface in FIG. 4) in a state in which they are mutually detented. 2 and the inner end of the lock case 5 (see FIG. 3), the handle cylinder portion 2 is locked to the lock case 5 when the cylinder lock is locked by a dead bolt 11 having an L-shaped cross section.

また、上記デッドボルト１１の短辺部（図４で右端部）をデッドボルトの頭部としたとき、デッドボルト１１の頭部に対向する側に斜面を備えた角柱状のばね受け１２が配設されており、このばね受け１２の斜面部はハンドル筒部を貫通して錠ケース５の内周面に母線に沿って形成された長いガイド溝１４（図４参照）に摺動可能に係合している。   Further, when the short side portion (the right end portion in FIG. 4) of the dead bolt 11 is a dead bolt head, a prismatic spring receiver 12 having a slope on the side facing the head of the dead bolt 11 is arranged. The slope portion of the spring receiver 12 is slidably engaged with a long guide groove 14 (see FIG. 4) formed in the inner peripheral surface of the lock case 5 along the generatrix through the handle cylinder portion. Match.

更にまた、ばね受けの内端部に形成されたばね受け孔１４に一端を保持され、このばね受け孔の底面とデッドボルト１１の頭部との間に弾装された圧縮コイルばねとしての図示しないデッドばねの弾力により、デッドボルト１１は図４で左方に付勢されている。   Still further, a compression coil spring not shown in the figure is held at one end in a spring receiving hole 14 formed in the inner end portion of the spring receiver and is elastically mounted between the bottom surface of the spring receiving hole and the head of the dead bolt 11. Due to the elasticity of the dead spring, the dead bolt 11 is biased leftward in FIG.

このデッドボルト１１及びばね受け１２の組は、図４では図示を省略してあるが、ハンドル筒部２の中心軸線に関して対称的に一対設けられている。   Although not shown in FIG. 4, a pair of the dead bolt 11 and the spring receiver 12 is provided symmetrically with respect to the central axis of the handle tube portion 2.

上記した構造によれば、デッドボルト１１は図４に示す位置より更に外方に位置する筈であるが、図示の実施例におけるラッチ部においては、ハンドル筒部２の内筒底部に回動可能に保持された係止カム１５（図３及び図４参照）により図４に示す位置にあって、ハンドル筒部２を錠ケース５に係止している。   According to the above-described structure, the dead bolt 11 should be located further outward than the position shown in FIG. 4, but in the latch portion in the illustrated embodiment, it can be rotated to the bottom of the inner cylinder of the handle cylinder 2. At the position shown in FIG. 4, the handle cylinder 2 is locked to the lock case 5 by the locking cam 15 (see FIGS. 3 and 4) held on the lock case 5.

上記係止カム１５は、図５及び図６に示すように、ハンドル筒部２の軸線方向における外端（図６で右端）に円形のフランジを、内端に扇形のフランジ及び扇形の切欠１６を夫々形成した部材である。   As shown in FIGS. 5 and 6, the locking cam 15 has a circular flange at the outer end (right end in FIG. 6) in the axial direction of the handle tube portion 2, and a fan-shaped flange and a fan-shaped notch 16 at the inner end. Are members formed respectively.

上記係止カム１５の切欠１６には、図３に示すように、解錠カム１７が係合しているので、係止カム１５はこの解錠カム１７を介してシリンダ錠の内筒に一体的に連結されている。   Since the unlocking cam 17 is engaged with the notch 16 of the locking cam 15 as shown in FIG. 3, the locking cam 15 is integrated with the inner cylinder of the cylinder lock via the unlocking cam 17. Connected.

ちなみに、上記解錠カム１７は、図７及び図８に示すように、中央に小判形の連結孔１８を開口させた厚板円盤の裏面側に、円盤に対する投影形状が扇形の一対の係合突起１９、１９を一体に突設したもので、上記連結孔１８にシリンダ錠の内筒の断面小判形の図示しないテールピースを嵌合させることによりシリンダ錠に一体的に連結されている。   Incidentally, as shown in FIGS. 7 and 8, the unlocking cam 17 has a pair of engagements in which the projected shape with respect to the disk is fan-shaped on the back surface side of the thick disk having an oval connection hole 18 opened in the center. The protrusions 19 and 19 are integrally provided so as to be integrally connected to the cylinder lock by fitting a tail piece (not shown) having an oval cross section of the inner cylinder of the cylinder lock into the connection hole 18.

また、解錠カム１７は、上記係合突起１９を係止カム１５の対応する切欠１６に係合させることにより係止カムに連結されていることは上記した通りである。   Further, as described above, the unlocking cam 17 is connected to the locking cam by engaging the engaging protrusion 19 with the corresponding notch 16 of the locking cam 15.

そして、自動販売機の扉を開けて内側に商品を充填したり、コイン箱から金銭を回収するためハンドル錠をポップアップするときには、先ずシリンダ錠に合鍵を挿入してシリンダ錠を解錠し、更に合鍵を所定の方向に回動させることにより、解錠カム１７及びこれに連結された係止カム１５が図４において時計方向に回動する。   And when opening the door of the vending machine and filling the goods inside or popping up the handle lock to collect money from the coin box, first insert the key lock into the cylinder lock and unlock the cylinder lock, When the key is rotated in a predetermined direction, the unlocking cam 17 and the locking cam 15 connected thereto are rotated clockwise in FIG.

すると、デッドボルト１１が図示しない上記デッドばねの弾力に抗してデッドボルト１１の頭部をばね受け１２に近接する方向に移動させる結果、デッドボルトの頭部とは反対側の脚部が錠ケース５の付番しない係止孔から抜去され、ハンドル１が自由になり、また、前記図示しない押しばねの弾力によりハンドルの把手部３が図３で鎖線で示す位置にまで突出する（ポップアップする）。   Then, as a result of the dead bolt 11 moving the head of the dead bolt 11 in a direction close to the spring receiver 12 against the elasticity of the dead spring (not shown), the leg on the side opposite to the head of the dead bolt is locked. The handle 5 is removed from the non-numbered locking hole of the case 5 and the handle 1 becomes free, and the handle portion 3 of the handle protrudes to a position indicated by a chain line in FIG. ).

なお、ポップアップしたハンドルを錠ケース５或いは取付枠７に収容する（押込む）には、シリンダ錠に合鍵を差込んでこれを解錠方向に回動させ、図４で係止カム１５を時計方向に回動させてデッドボルト１１の脚部をハンドル筒部２内に引っ込めた状態でハンドルを錠ケース或いは取付枠内に押込むようにする。   In order to house (push in) the pop-up handle in the lock case 5 or the mounting frame 7, a key is inserted into the cylinder lock and rotated in the unlocking direction. The handle is pushed into the lock case or the mounting frame in a state in which the leg portion of the dead bolt 11 is retracted into the handle tube portion 2 by rotating in the direction.

また、ハンドル錠のラッチ部は、上記した構成のものに限定されることなく、例えば前記特許文献１、２及び４に示すもの、或いはその他のものを採用することができる。   Further, the latch portion of the handle lock is not limited to the one having the above-described configuration, and for example, those shown in Patent Documents 1, 2, and 4, or other ones can be adopted.

一方、ハンドル１の下方における取付枠７内には、図３に示すように、作動装置２１が配設されている。   On the other hand, in the attachment frame 7 below the handle 1, as shown in FIG.

この作動装置２１は、正、逆回転できるモータ２２の回転出力軸に横断面円形の棒状体である案内部材２３を同軸に装着し、この案内部材２３にらせん状の疎巻コイルばね２４を案内部材２３長さ方向に移動可能に巻装してある。   In this operating device 21, a guide member 23, which is a rod-like body having a circular cross section, is coaxially mounted on a rotation output shaft of a motor 22 that can rotate forward and backward, and a helical spiral coil spring 24 is guided to the guide member 23. The member 23 is wound so as to be movable in the length direction.

また、案内部材２３の外周面の長さ方向における中央部に、コイルばね２４のピッチ間隙を遊動できる単一の突起２５を突設している。   In addition, a single protrusion 25 that protrudes through the pitch gap of the coil spring 24 is provided at the center in the length direction of the outer peripheral surface of the guide member 23.

更にまた、コイルばね２４の両端を案内部材２３の半径方向における外方に延出させ、この延出部分をロックピース２６に係合させている。   Furthermore, both ends of the coil spring 24 are extended outward in the radial direction of the guide member 23, and this extended portion is engaged with the lock piece 26.

なお、上記作動装置の構成及び作用については、前記特許文献３に記載されているから、更に詳細な説明は省略する。   Note that the configuration and operation of the operating device are described in Patent Document 3 and will not be described in further detail.

ちなみに、図示の実施例におけるロックピース２６は、図９及び図１０に示すように、全体の形状が凸字形の厚板材で、上記案内部材２３とほぼ平行な位置関係で、案内部材２３の長さ方向に移動可能に案内されると共に、その錠ケース５に対向する側の一端に形成した係合爪２７を、錠ケース５を貫通して、ハンドルの筒部２の外周面に形成された図示しない錠止凹部に係合可能に臨ませている。   Incidentally, as shown in FIGS. 9 and 10, the lock piece 26 in the illustrated embodiment is a thick plate material having a convex shape as a whole, and the length of the guide member 23 is substantially parallel to the guide member 23. An engaging claw 27 formed at one end on the side facing the lock case 5 is formed on the outer peripheral surface of the cylindrical portion 2 of the handle through the lock case 5 while being guided so as to be movable in the vertical direction. It faces a locking recess (not shown) so that it can be engaged.

そして、上記コイルばね２１の延出部分を、ロックピース２６の中央部に長さ方向（図９で上下方向）に沿って形成された案内長孔２８に遊動可能に係合させている。   And the extension part of the said coil spring 21 is engaged with the guide long hole 28 formed in the center part of the lock piece 26 along the length direction (up-down direction in FIG. 9) so that free movement is possible.

ロックピース２６を上記のように構成することにより、作動装置のモータ２２の正、逆何れの方向の回動に対しても、コイルばね２４の延出部分が案内長孔２８中を移動する間はロックピース２６は動かず、モータ２２の回転数が定格に致り延出部分が案内長孔２８の一端に致る前後にモータへの通電を断つようにすると、モータ２２の回転子の慣性をコイルばねの延出部分の弾性変形という形態で吸収すると共に、上記延出部分の弾性変形が元に戻るときの弾力を利用してロックピースを駆動することができるので、ロックピース２６の作動を確実にすることができるばかりでなく、電磁アクチュエータとしてのモータの停止時のショックを減少させることができる。   By configuring the lock piece 26 as described above, the extension portion of the coil spring 24 moves in the guide slot 28 regardless of the forward or reverse rotation of the motor 22 of the actuator. The lock piece 26 does not move. If the motor 22 is turned off before and after the rotation speed of the motor 22 reaches the rating and the extension part hits one end of the guide slot 28, the inertia of the rotor of the motor 22 is stopped. Is absorbed in the form of elastic deformation of the extension portion of the coil spring, and the lock piece can be driven by using the elasticity when the elastic deformation of the extension portion returns to its original state. In addition, the shock when the motor as the electromagnetic actuator is stopped can be reduced.
