Abstract: A lash adjuster for a valve gear includes a plunger movable upward and downward and including a high-pressure chamber, a leak path defined by an inner circumferential surface of a body and an outer circumferential surface of the plunger so that operating oil reserved in the chamber leaks through the leak path, and a ring-shaped member located between the body and the plunger. The member projects into the leak path during normal operation and is elastically deformed radially inward with increase in oil pressure at the chamber side so as to be retreated from the leak path when abnormal movement occurs in the valve gear such that oil pressure in the chamber exceeds a normal range, thereby reducing flow resistance of the oil in the leak path. The member has a surface receiving oil pressure in the chamber thereby to elastically deform the ring-shaped member radially inward.

The second conductivity-type diffusion layer has a higher impurity concentration than that of the sinker layer. The second conductivity-type diffusion layer and the first conductivity-type collector layer are isolated from each other with an element isolation insulating film interposed therebetween.

Abstract: A return spring is formed using a compression coil spring that is installed so that its axial direction is an up-down direction. The return spring is provided in a high-pressure chamber, and powers a plunger in an upwards direction. A coil diameter of the return spring varies along the axial direction. When the return spring is in a maximally compressed state, an axial direction dimension (up-down direction dimension) is smaller than a dimension that is a thickness of a spring wire multiplied by the number of coil turns. Hence, an overall height of a lash adjuster A can be reduced in comparison to when a return spring with a constant coil diameter over an entire length is used.
