Abstract
A power transmission device is disclosed. The power transmission device includes a housing, a clutch unit, a heat conducting unit, and a heat conducting unit. The housing includes a wall portion. The housing is rotatably disposed, with the torque from the drive source being transmitted to the housing. The wall portion has a through hole formed therein. The clutch unit includes a friction surface engageable with the housing and disposed opposite to the through hole. The clutch unit is disposed in the housing so as to be rotatable relative to the housing. The heat conducting unit is disposed in the through hole and exposed in the housing. The temperature detecting unit is configured to detect a temperature of the heat conducting unit.
