<P>PROBLEM TO BE SOLVED: To provide a power transmission mechanism which maintains high quality. <P>SOLUTION: The power transmission device 60 is equipped with: a pulley 61 rotatably attached on the outer periphery of a boss part 4b of a housing 1 of an auxiliary machine; a fixed member 65 fixed coaxially with the rotary shaft 10 to an end 10b of a rotary shaft 10; and a connecting member 63 fixed to the fixed member 65 and the pulley 61 for connecting the fixed member 65 and the pulley 61. The fixed member 65 is provided with a fracture part 89 for blocking transmission of rotary power from the pulley 61 to the rotary shaft 10 by twisting and fracturing when a load torque of a predetermined value or more acts on the fixed member 65. <P>COPYRIGHT: (C)2007,JPO&INPIT |
