摘要： A seal structure is provided to block a clearance between a rotational casing and a fixed housing for driving a crawler of a crawler vehicle. A seal ring is held in a first annular holding groove provided in the fixed housing together with a first O-ring that biases the seal ring toward the outside of the first holding groove. A second holding groove having an opening facing the first holding groove is provided in the rotational casing to hold a slide ring having a higher rigidity than that of the seal ring together with a second O-ring that biases the slide ring toward the seal ring. A foreign object such as mud is thereby prevented from invading a gear chamber without increasing a frictional loss.

摘要： A fluid pressure pump motor includes a supply/discharge passage where both a hydraulic fluid pumped in to a fluid pressure pump and a hydraulic fluid discharged from the fluid pressure motor flow, and a variable valve provided in the supply/discharge passage to control the fluid path area of the supply/discharge passage. The variable valve reduces the fluid path area of the supply/discharge passage for simultaneously actuating the fluid pressure pump and the fluid pressure motor to be smaller than the fluid path area for actuating only one of the fluid pressure pump and the fluid pressure motor.

摘要： A fluid pressure drive unit is to supply a working fluid to and drive a fluid pressure actuator. The fluid pressure drive unit includes a fluid pressure pump for suctioning and discharging the working fluid, an electric motor arranged in parallel to the fluid pressure pump, the electric motor for driving and rotating the fluid pressure pump, and a power transmission mechanism for transmitting a power between a rotation shaft of the fluid pressure pump and a rotation shaft of the electric motor.
