油圧式バルブリフタ。 ′[Claims for Utility Model Registration] 1. In a hydraulic valve lifter in which a plunger that slides in the axial direction inside the body is returned to a predetermined position by a return spring so that the valve clearance is always maintained at zero, the returning force of the plunger is , a hydraulic valve lifter characterized by being provided with an auxiliary biasing means that increases only when the temperature is low. 2 The auxiliary biasing means is an auxiliary biasing member that is engaged in parallel with the return spring between the plunger and the inner periphery of an annular bimetal whose outer periphery is seated on the body and whose inner periphery protrudes toward the plunger when the temperature is low. The hydraulic valve lifter according to claim 1, which is a return spring. 3. The auxiliary biasing means is an auxiliary return spring that is connected between the body and the plunger in series with the return spring and presses the return spring toward the plunger at low temperatures. Hydraulic valve lifter. ′
