ABSTRACT:
To provide an attachment structure of a swash plate support, that is, an attachment structure which suppresses an unstably fixed state of the swash plate support and realizes easy attachment and detachment of the swash plate support to and from a casing. A casing of a piston pump and a swash plate support which is attachable to the casing include a displacement preventing device and a rotation preventing device. In the swash plate support and the casing, since an engaging pawl portion of the displacement preventing device engages with an engaging portion, relative displacements in a first direction and a second direction along the rotational axis are prevented, and since a pin member of the rotation preventing device fits in the pin fit hole, relative rotations around the rotational axis are prevented.
