Abstract: This rotation mechanism is provided with: a first member; a second member which is rotatably coupled to the first member by a pivot; and a torsion coil spring which applies force such that one from among the first member and the second member is rotated relative to the other. Any one of the first member and the second member is provided with a torsion coil spring-accommodating part in which a pair of protrusions facing each other in the axial direction of the pivot is provided. The pair of protrusions are configured so as to hold, around the axes of the protrusions, the two end portions of the coil shape of the torsion coil spring, and so as to protrude while being displaced in the radial direction of the coil shapes forming the two ends, with respect to the axial direction of the pivot.

Abstract: An assist grip includes a retainer having a secured part secured to an attachment surface, and a pair of shaft-supporting parts; and a grip body that has a pair of recessed parts provided at both ends, a guide groove through which the shaft-supporting parts can slide and which is formed in at least one of two inside surfaces facing each other, and bearing holes provided in both inside surfaces; the grip body being turned about the shaft-supporting parts as a fulcrum to switch between a storage position and a usage position. The guide groove extends from the open edges of the recessed parts toward the inner bottom surface, and at least one bearing hole of both inside surfaces has an elastic locking piece positioned in a bearing hole or in the terminal end of the guide groove, the piece matingly or retainingly locking an end part of a shaft-supporting part.

Abstract: An assist grip includes a hollow molding member in which a grip main member is formed by a gas assist molding method, a holding portion, and concave storage portions provided to be connected to both longitudinal ends of the holding portion by interposing curved portions; and is attached to an attachment-face side by holding tools supported in both storage portions. Each of the storage portions is partitioned by an inner side wall and an outer side wall facing each other in a longitudinal direction; an upper wall connecting upper sides of the side walls at a curved-portion side; a lower wall connecting lower sides of the side walls at a terminal side; and a bottom wall connecting to both side walls and the upper and lower walls at an outer face side. The upper walls include inclined faces wherein inner faces on a storage-portion side are inclined toward a bottom-wall.
