PROBLEM TO BE SOLVED: To provide a resin part capable of increasing a releasing load of a fastener-inserted metal cylinder to a resin body when fixing the resin part to an installing object surface by fastening of a fastener. SOLUTION: A installing hole 13 formed in an installing support part (a bracket) 12 of the resin part is formed by pressing a cylindrical metal insert 14 in a hole 12a of the installing support part 12. One slit 15 is formed in the metal insert 14 so as to extend in parallel to the axial direction. When installing the resin part in an installing object part 16, a bolt 17 inserted into the installing hole 13 is fastened (figure (a)). The metal insert 14 swells in a drum shape in the radial direction by a compressive load applied in the axial direction when fastening the bolt 17, and an expanding diameter at this time is enlarged relatively to fastening torque by the presence of the slit 15 (figure (b)).
