A differential power transmission device used for digital audio tape recorders and video cassette tape recorders. The device comprises a connecting gear adapted to move vertically for selectively engaging with a driving pulley gear, so as to selectively transmit the rotation force of the pulley gear to a driven gear. A vertical pivot member is provided for vertically moving the connecting gear so as to engage it with the pulley gear, so that the driven gear is driven by the rotation force of the pulley gear transmitted via the connecting gear. With this arrangement, the rotation force of the pulley gear can be more surely transmitted to the driven gear, without any malfunction. <IMAGE> |
