An oil pressure control valve is equipped with: a hollow valve body (61) in the peripheral wall of which multiple ports for circulating operating oil are formed penetrating the peripheral wall in the radial direction; a first spool valve (65), which is provided so as to be movable in the axial direction inside the valve body (61), thereby switching the connected state of the operating oil with respect to the multiple ports in accordance with the position to which the spool valve is moved; and a second spool valve (63), which is provided coaxially with the first spool valve (65) and moves in the axial direction inside the valve body (61), thereby switching the connected state of the operating oil with respect to the multiple ports, in conjunction with the first spool valve (65) and in accordance with the position to which the first spool valve (65) has moved in the axial direction. Thus, it is possible to simplify control and reduce the size of the device. |
