PROBLEM TO BE SOLVED: To reduce a burden on each part by reliably bringing a clutch mechanism into an unconnected state, when a preset external force acts. ! SOLUTION: A clutch mechanism has a stationary-side clutch member 81 and a movable-side clutch member 80. A protrusion 80c is formed on the clutch member 80. A recess 81c, into which the protrusion 80c is to be fitted, is formed in the stationary-side clutch member 81. In a state in which the protrusion 80c is fitted into the recess 81c, the clutch mechanism C is put into a connected state. The protrusion 80c and the recess 81c are brought into line contact with each other. ! COPYRIGHT: (C)2016,JPO&INPIT |
