Document Type and Number:

Japanese Patent JP4024979

Kind Code:

B2

Abstract:

A mechanical device for transmitting power includes a power-transmission pulley (3) rotatably mounted on a housing (1) of an automotive accessory, a drive plate (4) fixedly connected to a shaft end of a rotating shaft (2) of the automotive accessory, and a plurality of shear pins (15) via which the pulley (3) and the drive plate (4) are joined to each other. Each of the shear pins (15) has a notched portion (16) between opposing faces of the pulley (3) and the drive plate (4), and a flanged portion (17) formed at a position being offset from the notched portion (16) toward the drive plate (4) and interleaved between the pulley (3) and the drive plate (4) so that the notched portion (16) adjoins the flanged portion (17) and that both side walls of the flanged portion (17) abut the opposing faces of the pulley (3) and the drive plate (4). An inside diameter of each of a plurality of shear-pin insertion holes (18) formed in the drive plate (4), is dimensioned to be larger than an outside diameter of each of the shear pins (15) fixedly connected to the pulley (3), for easy assembling. The drive plate (4) is fixedly connected to the shear pins (15) by applying a tightening force in an axial direction of each of the shear pins (15) between a protruded end portion of each of the shear pins projecting outside of the shear-pin insertion holes (18) and an associated one of the flanged portions (17) of the shear pins (15).
