PURPOSE: A hydraulic speed increasing device for a vehicle is provided to reduce working hours and cost by assembling and disassembling easily with simple structure, and to drive safely by automatically shifting according to input speed. CONSTITUTION: A body(10) is fastened by plural support rods, and fitted to an insertion part formed at a side of a cylindrical case. A bearing(31) is combined with the center of a cap(30), and plural assembling holes are formed in the cap. An assembling part of the case is combined with an assembling part of the cap by a bolt. A hydraulic control unit(18) with plural hydraulic pumps(18a) is inserted to the middle of a passage shaft, and cylinder blocks(11,11') are inserted to the body. An engine shaft(17) is inserted to the center of the cylinder block, and fixed by a key(17a). Plural pistons(14) are inserted to plural cylinders(11a). A fixing plate(12) is fitted to the engine shaft, and fixed to a support rod by a bolt. A disk(12a) is rotated by a bearing(12b) and installed in the fixing plate. The piston reciprocates right and left by rotating the cylinder block according to the angle of the fixing plate.
