The invention provides a hydraulic device. In the hydraulic device, a first rotation member (25) and a second rotation member (36) are arranged so as to be rotatable relative to each other about the same center axis (O), the first rotation member (25) is provided with a cam (26), pistons (38a-38h) are arranged on the second rotation member (36) so as to be opposite to the cam (26), the pistons (38a-38h) are pressed to be in contact with the cam (26) by compression coil springs (40a-40h), and the second rotation member (36) is provided with oil chambers (41a-41h) whose volume increases and decreases as the pistons (38a-38h) move. The hydraulic device further has a first fluid passage and a second fluid passage through which oil flows into or is discharged from the oil chambers (41a-41h), and also has a passage switching device (8) for switching the inflow direction and the discharge direction of oil in the first and second fluid passages depending on the pressure difference between the first and second fluid passages.
