A pin assembly includes: a resin pin; and a collar fitted to a round shaft portion of the resin pin and having higher hardness than the resin pin. The round shaft portion is sheared to cancel connection between a first plate and a second plate upon secondary collision of a vehicle. The collar includes an end face received by a reception surface of the second plate, and shears the round shaft portion in a shear plane along the end face upon the secondary collision. The round shaft portion includes a hollow hole. An inner circumference of the hollow hole includes a straight portion which has a generating line parallel to an axial direction of the round shaft portion and which is traversed by a plane including the end face of the collar.

The invention provides a natural fiber-reinforced thermoplastic resin injection molding having an excellent ability to discharge static electricity. The natural fiber-reinforced thermoplastic resin injection molding is obtained by injection-molding with using natural fiber-reinforced thermoplastic resin pellets as a molding feedstock containing natural fibers as reinforcing fibers, has a natural fiber content of from 20 to 60 wt %. The natural fibers have an average length of from 1.5 to 4.0 mm. The natural fiber-reinforced thermoplastic resin injection molding has an electrostatic voltage half-life, as determined by the half-life measurement method specified in JIS L 1094, of less than 40 seconds.
