Abstract

PURPOSE:To aim at stabilization of a supply oil pressure by disposing an oil pressure switching means in an oil pressure supply passage leading to the oil pressure chamber of a connection switching mechanism for cam followers, and providing a relief valve in the oil pressure switching means. CONSTITUTION:An oil pressure supply passage 31 is connected to the oil pressure chamber 29 and the oil pressure tappet of a connection switching mechanism 10 for cam followers 7, 8, 9. In the oil pressure supply passage 31 is disposed an oil pressure switching means 50 for switching and supplying high and low oil pressures. In the oil pressure switching means 50 is provided a relief valve 55 for releasing an oil pressure when the oil pressure supplied to the oil pressure supply passage 31 exceeds a predetermined value. Therefore, the upper limit of the supply oil pressure is determined so that the oil pressure can be kept constant, thereby enabling the stabilization of the supply oil pressure.
