An attachment structure for a resin part of a motorcycle includes an attaching portion with a nut provided on a side of a vehicle main body, a resin part having an attached portion with a bolt insertion hole, and a shoulder bolt for attaching the attached portion to the attaching portion with the nut. The shoulder bolt has a threaded shaft portion, a washer, a head portion, and a large diameter portion arranged between the washer and the threaded shaft portion, the large diameter portion being thicker than the threaded shaft portion and thinner than the washer. A thin guide piece protruding toward a radially inner side for regulating radial movement of the shoulder bolt within a predetermined range is integrally formed on an inner circumferential surface of the bolt insertion hole. The guide piece is configured to be deformed by the large diameter portion of the shoulder bolt. |
