Support feature null of unrestricted fluctuation

摘要

PURPOSE:To block a joint member from drop-out while setting the slidable outer peripheral surface of a ball joint in a slide circle of a spherical bearing to prevent the joint member from breaking down by connecting a body casing to the joint member in a support mechanism through an elastic support member. CONSTITUTION:Even if a ball joint 28 of a joint member 30 is dropped out of a spherical bearing 26 in a casing body 22 by frequent use and the progress of wear due to lubricant shortage in the bearing, the joint member 30 is connected to the casing body 22 through a coiled spring 58, so that said both member and body 30, 22 are suspended and held within the range of expansion and contraction of the coiled spring 58. Thus, a toy body including the joint member 30 is blocked from drop-out. Further, even if the toy body is subjected to large amplitude since the slide outer peripheral surface 28a of the ball joint 28 is set in the slide circle of the spherical bearing 26, any unnecessary external force is not applied to the joint member 30 including a shaft 42.
