LOCK DEVICE AND DOOR BODY FALL PREVENTION DEVICE HAVING THE SAME
To provide a rotary lock member preventing tooth jumping when locking in a lock device in which the rotary lock member locks a locked portion 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 has a plurality of locked portions on an outer periphery and rotates integrally with a shaft, and a rotary lock member 8 that can be locked with the locked portions. 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 911 are alternately and continuously formed in a circumferential direction on the outer periphery of the wheel 9. A lateral portion of each convex 910 is a plurality of locked portions. A dimension in the circumferential direction of each concave 911 is larger than that in the circumferential direction of each convex 910.SELECTED DRAWING: Figure 22
【課題】回動ロック部材が、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、ロック時における歯飛びを防止する回動ロック部材を提供する。【解決手段】外周に複数の被係止部を備え、シャフトと一体で回転するホイール９と、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９１１が周方向に交互に連続状に形成されており、各凸部９１０の側方部位が複数の被係止部となっており、各凹部９１１の周方向の寸法は、各凸９１０部の周方向の寸法よりも大きい。【選択図】図２２
