摘要： A working vehicle that uses the output of an internal combustion engine (30) as a working power and a traveling power includes an accelerator pedal (1) that increases a rotation speed of the engine (30) when depressed and a transmission (40) that shifts a rotation of the engine (30) and applies the shifted rotation to the traveling power. A speed ratio control device of the transmission (40) calculates a first target vehicle speed (Wne) according to the rotation speed of the engine (30), calculates a second target vehicle speed (Wu) according to a depression amount of the accelerator pedal (1), and controls the speed ratio of the transmission (40) on the basis of the smaller of these target vehicle speeds. As a result, a vehicle speed according to the depression amount of the traveling accelerator pedal (1) is obtained even when the internal combustion engine (30) rotates at high speed.

摘要： PROBLEM TO BE SOLVED: To provide a swash plate type piston pump motor in which each shoe slides without extending off a swash plate, and its size can be reduced and an inclined rolling angle of the swash plate can be large. SOLUTION: A swash plate type piston motor 1 in which an inclined rolling angle of a swash plate 40 can be changed, includes a swash plate back journal 41 protruding having an arc-shaped section from behind a swash plate 30, and a bearing 42 for slidably supporting the swash plate back journal 41. The swash plate 40 rotates about an inclined rolling axis O40, and the inclined rolling center axis O40 is arranged so as to intersect a rotational axis O5 of a cylinder block 4, and the inclined rolling axis O40 is located in a direction moving away from the cylinder block 4 relative to a shoe rocking center surface determined by rolling center point of each shoe 22, and in a direction approaching the cylinder block 4 from a back 40b of the swash plate 40.
