Abstract:
Disclosed is a vehicular drive device comprising: a transmission mechanism that transmits a driving force from a drive source to a wheel via a shaft member; and a case that houses the transmission mechanism, and at least a portion of the shaft member. The case includes a gear case part in which an oil that can be lifted up by rotation of a gear of the transmission mechanism accumulates, and a wall part that borders at least a lower side of a space around the shaft member, and extends along an extending direction of the shaft member. The space around the shaft member communicates with the inside of the gear case part, on one side in the extending direction of the shaft member, and includes an object placement space in which an object to be lubricated by the oil is disposed, or communicates with the object placement space, on the other side. The oil lifted up by the rotation of the gear of the transmission mechanism is supplied to the object to be lubricated in the space around the shaft member, or to the object to be lubricated, via the space around the shaft member.
