摘要：Disclosed is a power transmission apparatus which can require no high precisionmachining and can reduce a drag torque, and is provided with a clutch device having a highresponsiveness and a large engagement force. The power transmission apparatuscomprises an input shaft 21, an output shaft 22, a clutch device 23, and an actuator 24. Theclutch device 23 comprises a clutch hub 31, a clutch housing 32, a clutch pack 33
constituted by a plurality of inner clutch plates 61 and a plurality of outer clutch plates62, an input side cam mechanism 34 for pressing the clutch pack 33 toward the outputshaft 22, an output side cam mechanism 35 for pressing the clutch pack 33 toward theinput shaft 21, a return spring 36 for urging the clutch pack 33 to have its elementsmoved away from each other, and a drive shaft 37 having an input side gear 37n fortransmitting the driving force of the actuator 24 to the input side cam mechanism 34, andan output side gear 37d for transmitting the driving force of the actuator 24 to theoutput side cam mechanism 35.
