A swash plate type hydraulic motor switchable between high speed and low speed, comprises a main case, a cylinder block supported in the main case to be rotatable about a rotational axis, the cylinder block including a plurality of plungers having longitudinal axes extending parallel to the rotational axis, a swash plate supported in the main case for contacting forward ends of the plungers and pivotable about a pivotal axis between a high speed position and a low speed position, the pivotal axis extending parallel to a plane perpendicular to the rotational axis, and two trunnions projecting on the pivotal axis from opposite peripheral positions of the swash plate. The pivotal axis is located in a region between and close to a first reference plane extending perpendicular to a plane defined by the forward ends of the plungers in the low speed position, intersecting the rotational axis, and extending parallel to the pivotal axis, and a second reference plane extending perpendicular to a plane defined by the forward ends of the plungers in the high speed position, intersecting the rotational axis, and extending parallel to the pivotal axis.
