PURPOSE: A power transmission device having a clutch function is provided to offer improved performance by including a drive bevel gear having a first through-hole at the center. CONSTITUTION: A drive bevel gear(20) includes a first through-hole(21). A longitudinal direction drive device(60) is inserted into the first through-hole. The longitudinal direction drive device is slid to the drive bevel gear. A drive device includes a lateral direction groove(61) restricted at a free end. A groove is inclined to the shaft of the drive bevel gear. An actuator(50) is mounted at the free end of the drive device. A channel(51) is restricted inversely to the actuator. A shaft(52) successively extends through the actuator and groove. An idle bevel gear(30) has a second through-hole. A coupling(40) is slidably inserted into the second through-hole. |
