Abstract:
Provided is a press board laminate, which is formed by laminating a plurality of punched metal boards, and suppresses dropping of burrs at the time of assembling a press-fitting member to the press board laminate. A press board laminate (15a) is integrally configured by laminating a plurality of punched metal press boards, and a shaft (5) is to be press-fitted in an inner circumferential hole (21) by having a shaft position in the circumferential direction determined. Press boards (19, 19a, 19b) are laminated in a state wherein the punched directions are aligned with each other. Furthermore, the press board laminate (15a) has a key groove (34) having a complementary shape with respect to a key (26) of the shaft (5), said key being provided for the purpose of determining the circumferential position. The key groove (34) of the press board laminate (15a) includes a protruding portion (36), which protrudes in the diameter direction compared with other press boards (19, 19b), said protruding portion being formed on at least one press board (19a) positioned at the laminate-direction end portion equivalent to the front portion in the punched direction.
