Abstract:
1. A shaft fixing structure, comprising: a bracket that fixes en end portion of a shaft; a shaft fixing clip comprising: a bush comprising: said shaft inserted inside said bush to be fixed by the shaft fixing structure, the shaft comprising a groove into which said shaft fixing clip is fitted; and a peripheral wall that extends from a bush tip end opposite to the flange to the pair of circumferential slits, wherein the end portions of the metal wire member are crossed in an end portion of the second loop to respectively protrude toward diametrical sides, wherein tip ends of the end portions are bent, wherein the second loop that is positioned on a side of the end portions is configured as a shaft clamping portion, wherein bent portions of the tip ends of the end portions are configured as the pinch portion, wherein the pinch portion is bent in an axial direction of the shaft such that the clip fits the shaft, wherein the shaft fixing clip is fittingly attached to the circumferential slits, and wherein portions of the peripheral wall, corresponding to middle portions of the pair of circumferential slits and extending from the bush tip end to the pair of circumferential slits, are thinned to form parallel chords to reduce an outer diameter of the peripheral wall and to reduce an amount of the pinch force required to expand the second loop for passing over the outer diameter of the peripheral wall compared to an amount of the pinch force required without the thinning of the portions of the peripheral wall.
