ていた。Generally, in a hydraulic power steering device,
The operating oil flowing out of the actuator flows into the reservoir tank. Conventionally, a metal press tank is used for the reservoir tank, and in such a reservoir tank, the working oil containing abrasion particles mixed in the actuator and impurities of a hydraulic circuit is recirculated to the actuator. To prevent this, a filter was attached to the end of the pipe for inflow of the hydraulic oil into the reservoir tank to filter the hydraulic oil. The inflow pipe is configured to penetrate and fix to the reservoir tank body from the outside thereof, and has a structure in which the filter is attached to an end portion of the inflow pipe.
