<p>PURPOSE:To fit a fitting member into a recessed part in the neutral position of a swash plate with which the head part of a piston is brought into contact by placing said fitting member in a position eccentric to the rotary shaft center of its holding cylinder body and rotating said holding cylinder body to move the position of said fitting member. CONSTITUTION:A main spindle is rotatably supported in a body casing 1 and a cylinder block 3 is installed on the main spindle. And, plural pistons 4 are reciprocatingly provided on the cylinder block 3 and the head parts of the pistons 4 are brought into contact with a swash plate 5. In this device, a positioning member 14 is rotated accompanying the rotation of the driving shaft 9 of the swash plate 5 and, when a fitting member 22 which is placed on the recessed-in part 21 of a holding cylinder body 20 installed on the body casing 1, is positioned in a recessed part 18 provided on a circular arc shape part 17 of the positioning member 14, the fitting member 22 is fitted into the recessed part 18 to position the swash plate 5 in a neutral position. In this case, the recessed-in part 21 is formed in a position eccentric to the rotary shaft center of the holding cylinder body 20.</p> |
