ABSTRACT:
The first maximum inclination angle θ1is a maximum inclination angle of a link member45allowed by a clearance between a slit41sof a rotor21and one end45aof the link member45; the second maximum inclination angle θ2is a maximum inclination angle of the link member45allowed by a clearance between a slit43sof a swash plate24and the other end45bof the link member45; the third maximum inclination angle θ3is a maximum inclination angle of a first linking pin46allowed by a clearance between the first linking pin46and a first bearing hole41a; the fourth maximum inclination angle θ4is a maximum inclination angle of a second linking pin47allowed by a clearance between the second linking pin47and a second bearing hole43a; and the fifth maximum inclination angle θ5is a maximum inclination angle of the swash plate24with respect to the drive shaft10allowed by a clearance between the drive shaft10and a pair of the tilting guide faces37, 37. Relations (θ3+θ4)<θ5<θ1, θ2are established.
