面倒であるという問題点があつた。(Problems to be Solved by the Invention) The conventional mounting brackets 16 and 18 were made as small as possible in order to reduce the weight of the bicycle as described above. As shown in FIG. 8, the intersection between the rear tire 4 and the lower running portion 11a of the stretched chain 11 was not partitioned. For this reason, muddy water etc. splashed up by the rear tires 4 while running accumulates on the lower running part 11a of the chain 11 and washes off the lubricating oil, causing rust, which significantly reduces the durability of the chain 11. There was a problem in that maintenance inspections such as lubrication had to be carried out frequently as a rust prevention measure, which was extremely troublesome.
