BICYCLE

摘要

PROBLEM TO BE SOLVED: To perform simple detaching and secure attaching of an auxiliary wheel to a bicycle. SOLUTION: An auxiliary stay 5 holding the auxiliary wheel 4 is held and fixed between the front position from a pivotal point of a rear wheel 1 of a chain stay 3 and a mounting bracket mounting 8 to it through a screw body 10. Two pairs of pawls 9 engaging with the upper and lower sides of the chain stay 3 are formed on the mounting bracket 8. Holding and fixing are secured and generation of looseness is prevented since slippage or the like is not generated by an engagement of the pawl of the mounting bracket 8 with the upper and lower sides of the chain stay, and the auxiliary stay 5 and the mounting bracket 8 of the shape covering this are square or the like.
