This idea is as described above, and this chain case has upper and lower grooves that open toward the hole edge side formed on the inner surface of the rear edge of the rear end of the elongated hole for fitting the chain stay formed in the case body. The opposing edges of the main body support fittings fit together, and the case main support fitting is a metal plate piece that also serves as a washer for the chain stay fastening nut to the rear wheel axle, and a hole is formed in the center to allow the rear wheel axle to pass through. By attaching the main body support fitting to the rear wheel shaft in advance when screwing the chain stay fastening nut, the case main body support fitting becomes completely fixed, and the case body is attached to this support fitting using the groove. Therefore, the supporting metal fittings are not involved in opening and closing the tail end member of the case, and therefore, the fitting part of the case body and the tail end member or the tail end member is similarly fastened to the rear wheel shaft using a chain stay fastening nut. Excellent effects such as eliminating the trouble of having to loosen the chain stay fastening nuts one by one when removing the tail end member, which is seen in conventional fixing products, and eliminating the need for extra adjustments resulting from loosening the chain stay fastening nuts. There is.
