Abstract
Provided is a power transmission device with which it is possible to minimize transmission of an excessive external force. This power transmission device has an input lever, an output lever, and a housing that are capable of moving relative to each other and that are mechanically connected to each other so as to be capable of transmitting power therebetween. The power transmission device has: a main spring disposed on a first power transmission path that is for transmitting power between the input lever and the output lever; a return spring disposed on a second power transmission path that is for transmitting power between the input lever and the housing; and a damper disposed on a third power transmission path that is for transmitting power between the output lever and the housing.
