Abstract: A fastening portion structure of a resin part including a tubular member integrally embedded therein by insert molding, and an insertion hole formed inside the tubular member, in which a screw member is inserted through the insertion hole, and the tubular member is compressed in an axial direction by the screw member, so that the resin part is fixed to a predetermined member. An inner peripheral surface of the tubular member is exposed in a region from one end to an intermediate position in the axial direction of the tubular member, but is covered by a resin in a region from the intermediate position to the other end, and the insertion hole is formed in a resin covering the inner peripheral surface of the tubular member.

Abstract: A vehicle grip structure including a body member and a grip, in which the body member is covered by the grip made of a synthetic resin, the grip includes an insertion hole in which the body member is inserted and a space portion provided along the insertion hole, multiple elastic protrusions are formed integrally with the grip and dispersedly on one of an inner peripheral-side wall surface and an outer peripheral-side wall surface of the space portion so as to protrude toward the other wall surface, when the grip is held by a driver, the elastic protrusions are pressed against the other wall surface and elastically deformed, and the elastic protrusions are arranged in a grid pattern in which adjoining ones of multiple polygons of the same shape have a common side, and are positioned so as to form each side of the polygons.
