<p>A receiving member is provided so as to be capable of rotation across a fixed angle between a first position and a second position, and has a trapping portion for a received member, and a control pin, wherein trapping of the received member, or releasing of the received member that has been trapped, is achieved by the trapping portion in the first position, and assisting of a moveable body is achieved by rotating from this trapped state to the second position. A slider, which is provided with a guide channel for the control pin, is provided on a side of the receiving member. The slider is biased in a direction that is proximal to the receiving member. The guide channel has a corner portion with a biased end side on a bent or curved external side. When the receiving member is in the first position, the control pin is on one side of the corner portion of the guide channel, such that the rotation toward the second position of the receiving member is against the bias.</p> |
