Abstract
A motor unit () and the like are arranged on a frame body () covered with a cover (). A rod guide portion () is protruded from the frame body (). A lock rod () is disposed in this rod guide portion () so as to be freely movable. Weak portions () are provided on the rod guide portion () and the lock rod (), respectively. A deadlock mechanism () is disposed closer to a tip end side of the rod guide portion () than the guide-side weak portion () thereof. The deadlock mechanism () includes: a lock pin () urged to a deadlock engagement position where a region of the lock rod (), which is closer to the tip end side than the rod-side weak portion (), is locked; and a lock control member () that inhibits movement of the lock pin () to a locked position thereof before the weak portions () are cut off, and releases such regulation to the lock pin () after the weak portion () are cutoff. The lock control member () is disposed in a region where the movement of the lock pin () is regulated by assembling force between the cover () and the frame body (). When the cover () is detached from the frame body (), the lock control member () positionally shifts in a direction of releasing the regulation of the movement of the lock pin ().
