に危険であるという問題がある。(Problem to be solved by the invention) However, when riding on a long downhill road while braking while cycling, etc., the shoe body becomes hot due to frictional heat with the rim, and the surface melts, causing a fade phenomenon. Moreover, as this process is repeated, the rubber material becomes aged in a short period of time, which is extremely dangerous if an accident such as breakage occurs during braking.

る。(Means for Solving the Problems) In order to achieve the above objects, the present invention includes a shoe body 1 that is pressed against the rim of a wheel, and a shoe body 1 that is held and fastened to brake arches 2 and 3. A brake shoe 5 equipped with a shoe holder 4 is characterized in that a liquid crystal layer 9 that changes color due to frictional heat generated by the rim and the shoe body 1 is provided in a recess 8 provided at least on the side surface of the shoe holder 4. do.

に発現している。(Function) When the brakes are applied on a downhill road, the shoe body 1 presses against the rim, and the temperature between the two, especially the shoe body 1, gradually becomes high due to frictional heat. At this time, as the temperature rises, the color of the liquid crystal layer 9 gradually changes, and eventually reaches the limit of a warning color. The runner may notice the warning color by looking at the liquid crystal layer 9 while riding, and then stop the bicycle and run with the shoe body 1 cooled. 1 can be driven safely without any damage. The temperature of the shoe body 1 increases little when driving on flat ground or when the brake operation time is short, and therefore appears in a color other than the warning color.

部８の形状は長溝とすることが好ましい。 In the present invention, a recess 8 is provided on one side of the show holder 4, for example, the side facing the arches 2 and 3, that is, the bottom surface 7, and a liquid crystal layer 9 is provided in the recess 8. The surface of 9 is made flush with the bottom surface 7. It should be noted that cholesteric liquid crystal is preferable as the liquid crystal, and the position where the liquid crystal layer 9 is provided is the runner,
Although the best position for a third person to visually recognize is the bottom surface 7 as shown in the figure, the position is not necessarily limited to this, and may be, for example, the top surface. In this case, the shape of the recess 8 is preferably a long groove.

大である。(Effect of the invention) The present invention has a liquid crystal layer 9 that changes color due to frictional heat between the rim and the shoe body 1 in the recess 8 provided at least on the side surface of the shoe holder 4. This is effective in letting the runner foresee the danger due to the high temperature of the shoe body 1 when running. On the other hand, the liquid crystal layer develops different colors step by step depending on the temperature of the shoe body 1 during normal driving, so it also has a decorative effect. Moreover, the above-described configuration of the present invention has great practical effects in that it is extremely simple, easy to manufacture, and can be manufactured at low cost.
