A spherical pivot portionis formed on the top of the adjusting screw, and an engaging holeis formed in the top end of the pivot portion. The adjusting screw is rotated in the fastening direction by rotating operation of a turning tool T engaging with the engaging hole, and the bottom face of the adjusting screwis pressed against the friction member, thereby holding the adjusting screwin pushed-in state and making mounting of the lash adjuster to a swing arm type valve gear easy.
