いた。However, if the signal transmission component 1 is attached to only one spoke 3 as in the prior art, the signal transmission component 1 is not affected by external force such as centrifugal force or vibration during running of the bicycle. Slips on the spoke 3 and moves to the outer peripheral side or the inner peripheral side of the wheel W to be displaced from the proper mounting position, or the signal transmission component 1 rotates around the spoke 3 to be displaced from the proper mounting position. Or there was a risk. There are various methods for attaching the signal transmitting component 1 to one spoke 3 such as sandwiching the spoke 3 with the attaching portion 2 or tightening the spoke 3 with a set screw provided on the attaching portion 2. However, any of the above methods causes loosening of the mounting state with the passage of time, so that it has been difficult to prevent the above-described positional deviation and rotation from being completed.

態が起こりにくい。[0010] In the present invention, the signal transmission component includes an attachment portion that straddles the two spokes of a wheel having a plurality of spokes arranged in an outwardly extending state and is attached to the two spokes. I have. With this configuration, when the signal transmission component is mounted on the wheel via the mounting portion, 2
The spokes prevent displacement of the signal transmission component due to rotation. In addition, since the two spokes are arranged in an outwardly expanding state, the mounting portion attached to the two spokes slides on the two spokes, and the signal transmission component moves to the outer peripheral side or the inner peripheral side of the wheel W. It is unlikely that the position will shift.

うになる。The effect of preventing such a displacement due to the movement of the signal transmission component is that the mounting portion forms an opening angle corresponding to the opening angle formed by the two spokes, and the two spokes are connected to each other. When a pair of through holes separately inserted are provided, it is more reliably and remarkably exhibited. That is, when two spokes arranged in an outwardly extending state are inserted into a pair of through holes of the mounting portion, the interval between the two spokes is narrower on the inner peripheral side of the wheel than the mounting portion of the mounting portion. Because the distance between the two spokes on the outer side of the wheel is wide, it is difficult for the mounting part to move to the inner side and the outer side of the mounting location. This is useful for preventing displacement of the wheel due to the movement of the signal transmission component toward the inner circumference or the outer circumference of the wheel. Therefore, according to the present invention, by the rotation of the wheel accompanying the traveling of the bicycle, the signal transmission component attached to the wheel always passes in a proper state at a position facing the vehicle speed detection sensor, and the vehicle speed detection sensor is accurately detected. To work.

動による位置ずれを起こさないように取り付けられる。In the present invention, the mounting portion is divided into a main portion and an auxiliary portion that can be connected to each other, and the main portion and the auxiliary portion are connected to each other to form a pair of the through-holes. It is desirable to have a pair of grooves that form the holes. According to this, the signal transmission component is mounted on the wheel by simply performing the work of joining the two spokes to each of a pair of grooves provided in the main part and the auxiliary part by connecting the main part and the auxiliary part. Attached so that there is no displacement due to rotation or movement.

によって適正に定めることが可能である。In the present invention, since the pair of through holes of the mounting portion has an opening angle corresponding to the opening angle formed by the two spokes arranged in an outwardly expanding state, the signal transmission component has The mounting location is limited to one location in the radial direction of the wheel. For this reason, the position of the signal transmission component cannot be shifted in the radial direction of the wheel to adjust the positional relationship with the vehicle speed detection sensor. It can be properly determined by adjusting the mounting position of the.

ある。In the present invention, the pair of through-holes are provided separately at one end and the other end located on opposite sides of the flat-shaped mounting portion. It is desirable to adopt a configuration in which the magnet is provided at the center between the two, and a light reflecting surface is formed on the surface of the mounting portion. According to this, not only does the signal transmission component exhibit the function of operating the vehicle speed detection sensor, but the light reflection surface formed on the surface of the mounting portion reflects light from the oncoming vehicle in front and the automobile behind. It informs the existence of bicycles and motorcycles, so driving safety is enhanced. In particular, since the mounting portion is formed in a flat shape having a size that straddles two spokes, it is possible to increase the area of the light reflection surface. The effect of notifying the existence of the motorcycle is remarkably exhibited, and excellent driving safety is exhibited.
In addition, since this effect is exhibited only by forming a light reflecting surface on the surface of the mounting portion of the signal transmission component, there is an advantage that traveling safety can be improved without using another component.

By doing so, not only does the signal transmission component 1 exhibit the function of operating the vehicle speed detection sensor S (see FIG. 3), but also the light reflecting surface 50 formed on the entire surface of the mounting portion 40 Reflecting the light from the car and the car behind it to notify the presence of a bicycle or motorcycle increases driving safety. In particular, since the mounting portion 40 is formed in a flat shape having a size that straddles the two spokes 3 (see FIG. 3), a large area of the light reflecting surface 50 is secured. Therefore, the effect of reflecting the light to notify the existence of the bicycle or the motorcycle is remarkably exhibited, and the excellent running safety is exhibited. The light reflecting surface 50 is desirably formed by employing a molding method that imparts light reflecting properties to the synthetic resin layer itself forming the main part 10 or the auxiliary part 20, but in some cases, It may be formed by attaching a light reflective sheet to the surface of the part 10 or the auxiliary part 20. The “light reflecting surface” is a surface having a characteristic of efficiently reflecting the received light to the surroundings efficiently. Includes all reflective surfaces, as well as all surfaces that have been specially treated to provide light reflectivity.
