。It is a flexible cylindrical cover that covers the endless chain 7 that is wrapped around the driving sprocket 5 on the side of the pedal 4 and the driven sprocket 6 on the side of the rear wheel 3 so as to be able to move along with it over the entire length. The chain force bar is formed into a bellows shape that can be expanded and contracted in the longitudinal direction using an elastic material. The tooth portions 5a and -6a of the sprockets 5 and 6 are removably inserted into the widthwise center of the side wall 10a on the side of the sprockets 5 and 6, which is formed to have a small width. A chain cover structure characterized in that a groove 11 is formed in a V-shape with a large opening on the outer side over the entire length in the longitudinal direction.
