A variable displacement swash-plate compressor comprising: a housing having a swash plate chamber and a cylinder bore; a drive shaft that is rotationally supported by the housing; a swash plate that is rotational in the swash plate chamber by rotation of the drive shaft; a link mechanism arranged between the drive shaft and the swash plate, wherein the link mechanism allows an inclination angle of the swash plate to be changed with respect to a direction perpendicular to a drive shaft axis of the drive shaft; a piston reciprocally received in the cylinder bore; a conversion mechanism (11a, 11b) that causes the piston to reciprocate in the cylinder bore by a stroke corresponding to the inclination angle of the swash plate through rotation of the swash plate; an actuator configured to change the inclination angle; and a control mechanism that controls the actuator, wherein the link mechanism includes a lug member that is located in the swash plate chamber and is fixed to the drive shaft, and a transmitting member (5e, 5f) that transmits rotation of the lug member to the swash plate, the actuator includes the lug member, a movable body that is configured to rotate integrally with the swash plate and to move along the drive shaft axis, thereby changing the inclination angle, and a control pressure chamber that is defined by the lug member and the movable body and is configured such that pressure in the control pressure chamber is changed by the control mechanism to move the movable body, the variable displacement swash-plate compressor being characterized in that the movable body includes an acting portion (14a, 14b) that protrudes toward the swash plate and is configured to push the swash plate with the pressure in the control pressure chamber, the swash plate includes a receiving portion that protrudes toward the movable body, wherein the receiving portion contacts and is pushed by the acting portion (14a, 14b), the acting portion (14a, 14b) and the receiving portion contact each other at an acting position (F1-F5), a drive shaft-parallel line segment (A; B) is defined that contains the acting position (F1-F5) and connects a proximal end of the acting portion (14a, 14b) and a proximal end of the receiving portion to each other, while extending in parallel with the drive shaft axis, and the drive shaft-parallel line segment (A; B) is shorter when the inclination angle is maximized than when the inclination angle is minimized. a housing having a swash plate chamber and a cylinder bore; a drive shaft that is rotationally supported by the housing; a swash plate that is rotational in the swash plate chamber by rotation of the drive shaft; a link mechanism arranged between the drive shaft and the swash plate, wherein the link mechanism allows an inclination angle of the swash plate to be changed with respect to a direction perpendicular to a drive shaft axis of the drive shaft; a piston reciprocally received in the cylinder bore; a conversion mechanism (11a, 11b) that causes the piston to reciprocate in the cylinder bore by a stroke corresponding to the inclination angle of the swash plate through rotation of the swash plate; an actuator configured to change the inclination angle; and a control mechanism that controls the actuator, wherein the link mechanism includes a lug member that is located in the swash plate chamber and is fixed to the drive shaft, and a transmitting member (5e, 5f) that transmits rotation of the lug member to the swash plate, the actuator includes the lug member, a movable body that is configured to rotate integrally with the swash plate and to move along the drive shaft axis, thereby changing the inclination angle, and a control pressure chamber that is defined by the lug member and the movable body and is configured such that pressure in the control pressure chamber is changed by the control mechanism to move the movable body, the variable displacement swash-plate compressor being characterized in that the movable body includes an acting portion (14a, 14b) that protrudes toward the swash plate and is configured to push the swash plate with the pressure in the control pressure chamber, the swash plate includes a receiving portion that protrudes toward the movable body, wherein the receiving portion contacts and is pushed by the acting portion (14a, 14b), the acting portion (14a, 14b) and the receiving portion contact each other at an acting position (F1-F5), a drive shaft-parallel line segment (A; B) is defined that contains the acting position (F1-F5) and connects a proximal end of the acting portion (14a, 14b) and a proximal end of the receiving portion to each other, while extending in parallel with the drive shaft axis, and the drive shaft-parallel line segment (A; B) is shorter when the inclination angle is maximized than when the inclination angle is minimized.
