<p>The invention provides a chain adjusting device structure for a two wheel motor vehicle. The chain adjusting device structure is advantaged by capability of simply improving water resistance of a rocker arm opening part for insertion of a vehicle wheel shaft, and seeking reduction of manufacture cost and light weight. The chain adjusting device (45R) comprises: a first plate part (47) formed in a long strip along the length direction of the rocker (11), and closing a long square hole (42R); a shaft sleeve part (48) fixed on the first plate part (47), and with the inner periphery for insertion of the first plate part (47); a second plate part (49) fixed on the shaft sleeve part (48) in the mode of clamping the shaft sleeve part (48) with the first plate part (47), formed along the length direction of the rocker arm (11), and closing the other long square hole (42R).</p> |
