PROBLEM TO BE SOLVED: To provide a doll which has the joints flexed into the optional bending state so that it may make a pause favored by a user and the pose can be kept for a long time. SOLUTION: Even if the first member 30 of a joint member 50 is left standing after being rotated around the second member 40 into bending state, frictional force, atmospheric pressure and compressive stress work at a piston as movement prevention force which prevents the movement of the piston if the piston of a holding member 10 moves in a cylinder 12 to return to stretched state. Then, the movement of the piston is prevented by the movement prevention force and the joint member 50 can be kept stable in the bending state for a long time. COPYRIGHT: (C)2009,JPO&INPIT
