ABSTRACT:
A swash plate of a variable capacity swash plate compressor has a front-side sliding surface and a rear-side sliding surface. Pairs of substantially hemispherical shoes each perform relative rotation on the front-side and rear-side sliding surfaces of the swash plate, respectively, with respect to the circumference of the swash plate as the drive shaft rotates. A plurality of pistons each have one end thereof formed therein with a pair of concave support portions for each slidably supporting the shoe. At least one of the front-side and rear-slde sliding surfaces of the swash plate has a mounting recess formed at an outer peripheral portion thereof, the outer peripheral portion receiving no load which acts on the at least one of the front-side rear-side sliding surfaces of the swash plate. The mounting recess is used for assembling the each pair of the pairs of shoes with the swash plate and the pair of concave support portions at the one end of a corresponding one of the pistons. The mounting recess has a recess for placing one shoe of the each pair of the pairs of shoes therein and a guide face for guiding the one shoe onto a corresponding one of the at least one of the front-side and the rear-side sliding surfaces of the swash plate.
