LOCK DEVICE AND DOOR BODY FALL PREVENTION DEVICE HAVING THE SAME
To prevent a wheel from reversely rotating due to impact when locking in a lock device in which a lock member locks locked portions on a wheel outer periphery to restrict rotation of the wheel that rotates integrally with a shaft.SOLUTION: A lock device has a wheel 9, which rotates integrally with a shaft, and a rotary lock member 8 that can be locked with locked portions on an outer periphery of the wheel 9. The rotary lock member 8 locks the locked portions to restrict the rotation in a first direction of the shaft in the lock device. A convex 910 and a concave are alternately and continuously formed in a circumferential direction on the outer periphery of the wheel 9. A lateral surface 915 of each convex 910 is a plurality of locked portions. The rotary lock member 8 has a surface 80 whose tip is locked with the locked portion. An opening 83 into which the convex 910 can enter is formed on the surface 80. The rotation in a first direction of the wheel 9 is allowed and the rotation in a second direction is restricted in a state where the convex 910 enters the opening 83.SELECTED DRAWING: Figure 24
【課題】ロック部材がホイール外周の被係止部を係止することで、シャフトと一体で回転するホイールの回転を規制するロック装置において、ロック時の衝撃によるホイールの逆回転を防止する。【解決手段】シャフトと一体で回転するホイール９と、ホイール９の外周の被係止部に係止可能な回動ロック部材８と、を備え、回動ロック部材８が被係止部を係止して、シャフトの第１の方向の回転を規制するロック装置において、ホイール９の外周には、凸部９１０と凹部が周方向に交互に連続状に形成されており、各凸部９１０の側面９１５が複数の被係止部となっており、回動ロック部材８は、先端が被係止部に係止する面部８０を備えており、面部８０には、凸部９１０が侵入可能な開口８３が形成されており、凸部９１０が開口８３に侵入した状態において、ホイール９の第１の方向の回転は許容され、第２の方向の回転は規制される。【選択図】図２４
