To provide a gear change device which can improve electrical economy, and a drive unit.SOLUTION: In a drive unit 100, a gear change device 1 for an electric vehicle driven by a motor 2 has: an input shaft 47 connected to the motor; a gear change mechanism for switching a first state that a reduction ratio between the input shaft and an output shaft 48 connected to a driven side is a first reduction ratio, and a second state that a reduction ratio between the input shaft and the output shaft is a second reduction ratio; and a torque sensor 5 for detecting the torque of the output shaft. The torque sensor detects the torque of the output shaft during a gear change changeover period in which the first state and the second state are switched, and the motor is controlled on the basis of a torque detection signal from the torque sensor.SELECTED DRAWING: Figure 1

    【課題】電費を向上させることができる変速装置及び駆動装置を提供する。【解決手段】駆動装置100において、変速装置1は、モータ2で駆動される電気自動車用の変速装置であって、モータに連結される入力軸47と、被駆動側に連結される出力軸48との間の減速比が第1減速比である第1状態と、入力軸と出力軸との間の減速比が第2減速比である第2状態とを切り換える変速機構と、出力軸のトルクを検出するトルクセンサ5と、を有する。第1状態と第2状態とを切り換える変速切換期間において、トルクセンサは、出力軸のトルクを検出し、トルクセンサからのトルク検出信号に基づいてモータが制御される。【選択図】図1
