Vehicle drive device

The problem to be solved by the present invention is to provide a vehicle drive device capable of suppressing a decrease in efficiency of oil scraping lubrication when a drive wheel is in a slipping state. In order to solve the problem, the present invention provides a vehicle drive device (1) comprising: an engine (11); a motor generator (12); a torque transmission unit (3); a hydraulic circuit (4) having an oil pump (48) that is driven by the engine (11) and supplies the oil (O) in the oil reservoir (41) to the lubrication unit (6); a slip determination unit (56) that determines whether or not the drive wheel (101) is in a slip state; and a control device (5) that sets the travel mode to either an EV mode in which the engine (11) is turned off and the vehicle (100) travels, or an ECVT mode or an LU mode in which the engine (11) is turned on and the vehicle (100) travels. Furthermore, the control device (5) restricts the operation of the first oil pump (481) when the travel mode of the vehicle (100) is chang
