DRIVE DEVICE

To provide a drive device that can downsize the whole device.SOLUTION: A drive device 1 is equipped with a motor 2, a transmission mechanism 3, an inverter 7, a housing 6, a channel 90 in which a fluid flows, a refrigerant channel 70 in which a refrigerant flows, a pump 8 that pumps the fluid, and a cooler 9 that exchanges heat between the fluid and the refrigerant. The housing has a motor storage portion 81 that stores the motor, a transmission mechanism storage portion 82 that is located on one side in an axial direction of the motor storage portion and stores the transmission mechanism, an inverter storage portion 84 that stores the inverter, and a supporting portion 83 that is located on a radial outer side of the motor storage portion and on one side in a circumferential direction of the inverter storage portion, and is connected to an outer peripheral portion of the motor storage portion and a bottom portion of the inverter storage portion. The supporting portion supports the pump and the cooler. Either the pump or the cooler is disposed on the one side in the circumferential direction with respect to the supporting portion, and the other is disposed on the radial outer side with respect to the supporting portion.SELECTED DRAWING: Figure 1 【課題】全体の小型化を図ることができる駆動装置を提供する。【解決手段】駆動装置１は、モータ２と、伝達機構３と、インバータ７と、ハウジング６と、流体が流れる流路９０と、冷媒が流れる冷媒流路７０と、流体を圧送するポンプ８と、流体と冷媒との間で熱交換させるクーラ９とを備える。ハウジングはモータを収容するモータ収容部８１と、モータ収容部の軸方向一方側に位置し、伝達機構を収容する伝達機構収容部８２と、インバータを収容するインバータ収容部８４と、モータ収容部の径方向外側かつインバータ収容部の周方向一方側に位置し、モータ収容部の外周部およびインバータ収容部の底部に接続される支持部８３とを有する。支持部はポンプとクーラを支持する。ポンプおよびクーラの何れか一方は支持部に対し周方向一方側に配置され、他方は支持部に対し径方向外側に配置される。【選択図】図１
