PURPOSE: To provide a power transmitting structure for reliably shutting off transmission of overload on the compressor side. CONSTITUTION: Driving force transmitting bodies 8 are supported to a projecting end 4-1 of a rotary shaft so as not to be relatively rotated and as to be slid. The driving force transmitting bodies 8 are fastened and joined to connecting arms 10, 11 of a pulley 6 by break screws 12, 13. The rotation of a vehicular engine is transmitted to a pulley 6 through a belt 7, and the rotation of the pulley 6 is transmitted to the rotary shaft through the break screws 12, 13 and the driving force transmitting bodies 8. When load torque on the compressor side is excessively increased, the break screws 12, 13 are broken. The preload is applied to the break screws 12, 13 by screwing of the break screws 12, 13 in relation to the connecting arms 10, 11. |
