Claim:
1. A variable displacement axial piston device comprising: a cylinder block that rotates around a rotational axis line; a plurality of pistons that are accommodated in the cylinder block in a relatively non-rotatable manner around the rotational axis line with respect thereto and in a reciprocating manner along the rotational axis line with respect thereto; a trunnion type movable swash plate capable of varying a reciprocating range in which the plurality of pistons can move; and a housing that accommodates the cylinder block, wherein the movable swash plate includes a swash plate main body that has an engagement surface with which free ends of the plurality of pistons are engaged, and a trunnion shaft that extends outward in a radial direction of the rotational axis line and is supported in a rotatable manner by a bearing portion provided in the housing so as to be located coaxially with a slanting axis line,
