Abstract

The present invention provides a vehicle drive device capable of improving relative positional accuracy between a liquid fluid sensor and other components. The cover member (72) has a filter insertion hole (94a) and a sensor insertion hole (82) connecting the inner side and the outer side of the cover member (72) in the installed state, and the oil sensor (80) is inserted into the sensor insertion hole ( 82) and fixed to the cover member (72). In addition, the filter insertion hole (94a) constitutes a part of the oil suction passage (94), and one end side of the oil suction passage (94) where the suction port (71a) for sucking oil is formed is disposed in the filter housing chamber (105). , and the oil suction passage (94) extends across the inside and outside of the casing (11). In addition, the oil suction path (94) is constituted by a filter (71) fixed to the cover member (72) for the flow path from the filter insertion hole (94a) to the suction port (71a).

Description

technical field [0001] The present invention relates to a vehicle drive device, and more specifically, to a vehicle drive device including a sensor. Background technique [0002] Patent Document 1 discloses a structure including an adapter arranged in the oil pan so as to close the opening of the side wall of the oil pan, and the adapter passes through a seal member and an annular stopper On the other hand, a plurality of mounting screws penetrating the side wall of the oil pan are oil-tightly mounted on the side wall of the oil pan. In addition, any member for oil pans, such as an oil level sensor, an oil temperature sensor, a heater, etc., is attached to this adapter in an oil-tight manner.
