<P>PROBLEM TO BE SOLVED: To provide a performance member for executing two pieces of operations, namely a rotary operation and an advance/retraction operation, by a single driving source. <P>SOLUTION: A movable accessory includes: a front arm 61 that includes a rotating shaft 63, and a front arm member attached to the rotating shaft 63, and rotates together with the rotating shaft 63 as the center; a fist part 71 that is movably held by the front arm member of the front arm 61 and advances to and retracts from the front arm member; a crank mechanism 81 for connecting a crank gear 82 to the rotating shaft 63 so as to transmit a turning force, and for connecting a crankshaft 83 to the fist part 71; and a drive part 81M for rotationally driving the crank gear 82 of the crank mechanism 81. The crank mechanism 81 forms a state that a turning force of the crank gear 82 is applied to the rotating shaft 63 to rotate the front arm 61 according to a rotational angle of the crank gear 82, and a state that the crankshaft 83 is oscillated without applying any turning force to the rotating shaft 63 to advance and retract the fist part 71. <P>COPYRIGHT: (C)2013,JPO&INPIT |
