To provide an electrically-driven gear transmission accurately reflecting driver's intention.SOLUTION: An electrically-driven gear transmission includes an electric motor, a shift fork, and a shift power transmission mechanism having a shift drum and an intermittent rotation mechanism. The intermittent rotation mechanism comprises a change shaft, a change lever unit including a change lever, a return spring, and a change cam. The shift power transmission mechanism is configured to displace the shift fork when the intermittent rotation mechanism performs a predetermined operation sequence from a state in which a phase angle of the change lever is a reference angle. The operation sequence is performed when the electric motor performs a predetermined rotation operation including rotations in both directions of a clockwise rotation and a counterclockwise rotation.SELECTED DRAWING: Figure 2

    【課題】運転者の意図が正確に反映される電動ギヤ変速機を提供する。【解決手段】電動ギヤ変速機は、電動モータと、シフトフォークと、シフトドラム及び間欠回転機構を有する変速動力伝達機構と、を備える。前記間欠回転機構は、チェンジシャフトと、チェンジレバーを含むチェンジレバーユニットと、リターンスプリングと、チェンジカムと、を有する。前記変速動力伝達機構は、前記チェンジレバーの位相角が基準角である状態から前記間欠回転機構が所定の動作シーケンスを行うと、前記シフトフォークを変位させるように構成されている。前記動作シーケンスは、前記電動モータが時計回り及び反時計回りの両方向の回転を含む所定の回転動作をしたときに行われる。【選択図】図2
