Abstract
Provided is a flow path structure of a power transmission device which is capable of removing gas from a lubricating fluid guided to a fluid reservoir while suppressing an increase in a size of the entire power transmission device. A gasket (63) has an extending portion which extends toward an inside of a transmission case (31). A flow path (70) which extends from an upper portion to a lower portion and guides lubricating oil discharged from a discharge mechanism (64) to an oil reservoir is formed inside the transmission case (31) using the extending portion. The discharge mechanism (64) discharges the lubricating oil toward an inner surface of the flow path (70).
Claims5
A flow path structure of a power transmission device which removes gas from a lubricating fluid guided to a fluid reservoir inside a casing of the power transmission device, comprising:
- a discharge mechanism configured to discharge the lubricating fluid supplied to a hydraulic operating mechanism disposed inside the casing into an inside of the casing,
- wherein the casing comprises a plurality of case members joined to each other at an opening edge of the casing,
- a gasket is interposed between the case members,
- the gasket has an extending portion configured to extend toward an inside of the casing from the opening edge,
- a flow path configured to extend from an upper portion of the casing to a lower portion thereof and to guide the lubricating fluid discharged from the discharge mechanism to the fluid reservoir is formed inside the casing and surrounded by the extending portion and an inner wall surface of the casing, and
- the discharge mechanism discharges the lubricating fluid toward the flow path.
