摘要： A motion converting section (31) and a translation bar (33) of a feedback mechanism (30) are provided between a lateral side of a swash plate (21) and a control sleeve (26) of a regulator (24). When the swash plate (21) is in a neutral position, the motion converting section (31) is located in an initial position (F-F) at one end of axial direction along an axis line (O-O) passing through a tilting center (C) of tilting motions, and, when the swash plate (21) is driven to tilt in a forward or reverse direction, displaced to the other end of axial direction along the axis line (O-O) to convert a tilting motion of the swash plate (21) into an axial displacement. Through the translation bar (33), the axial displacement is transmitted to the control sleeve (26) of the regulator (24) as an axial displacement.

摘要： A pair of leg portions are provided on a swash plate. A main hydrostatic bearing is provided on one leg portion, in communication with one supply/discharge passage through an oil guide passage, and an auxiliary hydrostatic bearing is provided on the other leg portion, in communication with the oil guide passage. Another main hydrostatic bearing is provided on the other leg portion, in communication with the other supply/discharge passage through an oil guide passage, and another auxiliary hydrostatic bearing is provided on one leg portion, in communication with the oil guide passage. By the main hydrostatic bearings and auxiliary hydrostatic bearings, dissociative forces are generated between the leg portions of the swash plate and a swash plate support member in balance with hydraulic reaction forces which are exerted on the swash plate by pistons.

摘要： A plurality of rotating side brake disks and a plurality of non-rotating side brake disks are arranged outside in the radial direction from a motor shaft in a brake case while alternately overlapping with each other. A frictional material is provided only on the non-rotating side brake disk in these rotating side brake disk and the non-rotating side brake disk. As a result, the weight of the rotating side brake disk can be reduced, and drag resistance of the rotating side brake disk rotating also in brake release can be reduced.
