Figures 1 to 5 show an embodiment embodying this invention. Figure 1 is a front view of the valve spring and retainer when extended, showing only the valve lifter and adjusting shim in cross section, and Figure 2 is a front view of the retainer. A perspective view, FIG. 3 is a front view of the valve spring and retainer during compression, showing only the valve lifter and adjusting shim in cross section, and FIG. 4 is a sectional view schematically showing the valve operating mechanism of an internal combustion engine in which the retainer is incorporated. , FIG. 5 is a partial perspective view of a valve spring, and FIG. 6 is a partial front view showing the relationship between a conventional retainer and a valve spring. In the figure, 13 is the seating surface of the retainer, 15 is the valve spring, 16 is the coil, 16a is the outer peripheral surface of the coil, 16b is the coil end surface, 17 is the protrusion, 18 is the inclined surface, A is the inclination angle, and d is the average coil diameter. , H is the height of the end face of the coil, and L is the axis of the valve spring.
