Abstract:
PROBLEM TO BE SOLVED: To provide a resin washer capable of suppressing damage of a washer even in a case where fastening stress is imparted in fastening.SOLUTION: A resin washer 10 comprises a resin plate, and an insertion hole 11 through which a shaft is inserted is formed in a center of the resin washer. In an annular plate part 13 on the outer periphery of the insertion hole 11, when viewed from a direction orthogonal to an insertion direction of the shaft with respect to the insertion hole 11, a top part 14 and a bottom part 15 are alternately formed along a circumferential direction. The top part 14 and the bottom part 15 are connected with a connection part 16, and form a waveform. The connection part 16 is formed so as to be thinner than the top part 14 and the bottom part 15.SELECTED DRAWING: Figure 2
