Claims

[Scope of utility model registration request]

An adjustment screw is screwed to one end of the rocker arm of the engine and has a convex spherical sliding surface at the lower end of the shaft, and has a concave spherical seating surface that slidably fits into the sliding surface and has an outer circumferential portion. A cap having an annular groove formed therein, an upper fitting portion that fits loosely with the shaft portion of the adjusting screw, a lower fitting portion that elastically presses and fits into the annular groove of the cap, and both of the fitting portions. and a wire clip that connects the adjuster screw and the cap.
