摘要： PROBLEM TO BE SOLVED: To provide a swash plate-type motor equipped with a cylinder hole structure for a tilting piston, with which abrasion resistance can be increased and the time required for a hardening operation is shortened.SOLUTION: Laser hardening is performed in the circumferential direction of a cylinder hole 18 for a tilting piston, only on a local portion (the hardened part 3) of the bottom inner-hole portion of the tilting piston-use cylinder hole 18, the local portion being struck by the end of the tilting piston 17 when the tilting piston 17 tilts due to compressive force from the swash plate. Laser hardening is not performed on portions of the tilting piston-use cylinder hole 18 other than the aperture part inner-hole portion and the bottom inner-hole portion.

摘要： PROBLEM TO BE SOLVED: To supply lubricating water between a cylinder body and a rod without providing a hydraulic pressure source separately.
SOLUTION: Between the cylinder body 12 and the rod 14 in a through-hole 22a of the cylinder body 12, a main seal 30 and a dust seal 31 are arranged side by side in the driving direction of the rod 14 to form a lubricating space 32 therebetween. A lubricating means 45 is provided for supplying operating water from pressure chambers 25, 26 into the lubricating space 32 when the operating water is discharged from the pressure chambers 25, 26. The lubricating means 45 has a lubricating passage 47 and throttles 48a, 48b. In the lubricating passage 47, a lubricating solenoid valve 48 is provided for communicating the pressure chambers 25, 26 with the lubricating space 32 when the operating water is discharged from the pressure chambers 25, 26.
