[Detailed Description of the Invention] The present invention relates to the improvement of a bicycle spoke protector. Specifically, in the rear wheel of a bicycle equipped with an exterior rear derailleur, the spoke protector is installed near the inside of the largest diameter sprocket of a multi-stage freewheel, and is attached to the rear wheel of a bicycle equipped with an exterior rear derailleur. This invention relates to a bicycle spoke protector for preventing the chain from falling between the largest diameter sprocket and the rear wheel and damaging the spokes or hub.

従来、自転車用スポークプロテクターは、一般に金属製

That is, such a conventional spoke protector p has a substantially disk shape with a boss hole k in the center, and has a shoulder portion e that borders the helical shaft portion C of the hub body a and the leg attachment portion d, and the aforementioned screw portion. Shaft C
The inside of the periphery of the boss hole of the spoke protector is sandwiched between the inner end wall g of the core f of the freewheel b which is screwed into the The circumferential edge part j is given elasticity in advance to press against the spoke S, and when assembled, it is supported in a fixed position by the clamping part and the spoke contact part.

That is, a non-threaded portion, that is, a groove m, is generally provided between the shoulder portion e and the screw shaft portion C of the hub body a in order to securely screw the core f up to the shoulder portion e. Generally, the diameter of the bottom of the groove is considerably smaller than the maximum diameter of the spiral portion C.

In view of the configuration of the hub body a, when assembling a conventional spoke protector, the diameter of the boss hole to be drilled in the center of the spoke protector p is set to be larger than the maximum diameter of the threaded portion of the threaded shaft portion C. It must also be larger, and its diameter must therefore be considerably larger than the bottom diameter of said groove m.

For this reason, when the spoke protector p is assembled, play occurs between the boss hole and the bottom of the groove m, making it difficult for the center of the spoke protector p to be concentric with the rotational axis of the hub a, making it difficult to see when driving. There was a problem in that it gave a sense of incongruity.

Also, the play between the boss hole and the bottom of the groove m is as follows:
Due to the fact that the spoke protector p is made of metal, there is a slight unevenness in the pressing force when the core f is screwed onto the screw shaft C, which prevents the freewheel b from being correctly attached to the bub body a. This not only adversely affects the function of the freewheel and transmission, but also causes the chain line to vibrate slightly from side to side with each revolution of the freewheel b, reducing chain efficiency.

Furthermore, the width q and radius r of the leg attachment part d of the hub body a vary depending on the specifications of each manufacturer, or even among the same manufacturer depending on the bicycle model, manufacturing method, materials used, etc., as shown in Fig. 6. And, as in the conventional example shown in FIG. 7, the part near the boss hole is slightly bulged outward in the bubble axis direction, and the annular stepped wall t on the inner side of the protector formed by this is connected to the leg attachment part d of the bubble body a. In the conventional spoke protector configured to abut and engage with the outer end corner U of the spoke protector, it is possible to adapt to various sizes and shapes (width and radius) of the leg attachment part d of the bub body a. However, it is necessary to prepare spoke protectors having many types of boss holes depending on the bub body to which the spoke protector is to be attached, which also raises the problem of increased manufacturing costs such as increased mold costs.

In addition, as another conventional example, there is one shown in Japanese Utility Model Publication No. 1253/1983, which requires a metal fitting to be installed by hooking it onto the spokes of a bicycle wheel. Even if the main body part is made of resin, there is a limit to reducing manufacturing costs because this installation requires attaching the metal fittings to the main body. It requires skill to attach it to the wheel.
