Claims

[Scope of utility model registration request]

In an axial plunger pump in which the swash plate is supported in an angle-adjustable manner by a convex cylindrical surface on the back surface of the swash plate, a pair of left and right support protrusions 2 having convex cylindrical surfaces 2a as end surfaces are provided protruding from the back surface of the swash plate. A pair of left and right support grooves 6 having the concave cylindrical surface 6a as the inner bottom surface are provided on the inner surface of the case end wall 5 that supports the pump main shaft 3 via the bearing 4 on the outer peripheral side of the bearing 4. In this swash plate support device, a swash plate 1 is supported by fitting a pair of left and right support protrusions 2 into the above-mentioned pair of left and right support grooves 6.
