BUSH AND ROTATION SUPPORT MECHANISM USING THE SAME AND ASSEMBLY METHOD OF ROTATION SUPPORT MECHANISM USING THE SAME

摘要

PROBLEM TO BE SOLVED: To inhibit rattling in a rotation support mechanism and thereby achieve good rotation support.SOLUTION: A rotation support mechanism 1 includes: a first member (a cushion frame 10) having a support hole 11; a bush 30 attached to the support hole 11; a shaft member 40 supported by the support hole 11 through the bush 30; and a second member (a back frame 20) which is rotatably connected with the first member through the shaft member 40. The bush 30 includes: a cylinder part 31; a first flange 32; and a second flange 33. The second member is located adjacent to the first member in an axial direction through the second flange 33. The bush 30 has a space D1 between the second flange 33 and the first member and is fixed to the first member in the cylinder part 31.SELECTED DRAWING: Figure 2
