Abstract
A valve lifter includes a guide cap mounted between a cam and the top end of a valve stem and which is slidably supported so as to be capable of moving in the axial direction. The guide cap has an end wall formed with a threaded through-hole. An adjusting bolt is threadedly engaged in the threaded hole. The adjusting bolt is biased toward the valve stem by a spring. The threaded hole and the adjusting bolt have serration-shaped threads so that the adjusting bolt can be moved toward the valve stem under the force of the spring. Since the adjusting bolt is threaded into the threaded hole formed in the guided cap, the axial length of the valve lifter is short.
