SUMMARY OF THE INVENTION [Technical Field] The present invention relates to a tire for a vehicle, and particularly relates to a light wire structure of a wheel. [Prior Art] A general bicycle wheel includes an axle, a wheel frame, and a tire mounted on the wheel frame. A plurality of spokes are used between the axle and the wheel frame. Each of the spokes has a threaded section at both ends (either the end is threaded and the other end is a hook) and can be combined with the axle and the wheel frame, respectively. Under the trend of lightweight design, the bicycle's spokes have changed from the early metal to the recently popular carbon fiber, in order to reduce the weight of the bicycle. Carbon fiber has light weight and high tensile strength. However, the carbon fiber is threaded thereon. Therefore, all of the current carbon fiber light Du, Xi Xi has a carbon fiber body and the metal connection at the two ends of the body is provided with a thread (or - is a thread, the other is enough for the carbon fiber body) The end is coated with the two metal joints. 2. The bonding force between the fibers and the metal is not good. Therefore, the n-filaments produced by the invention will be produced for a long time. Achieving the foregoing: hair = metal connector has high bonding strength. The structure comprises: - a body made of carbon of the wheel of the invention, and a two-piece connector, which is 1375627 i〇l, 05, 08 The at least one connecting member of the daily correction replacement page has a diameter reducing section having at least than the other portion. The connecting member can be placed at the outer end of the difficult end - the head or the crane path a recess is provided on the segment. The hard layer is provided with a -bonding layer. The bonding layer is made of the same material as the main body; the end of the main body covers the head of the connecting member and the bonding layer. And close to the bonding layer Therefore, the bonding strength between the connecting member and the main body can be greatly improved. [Embodiment] Referring to FIGS. 3 to 3, the H wire 1 of the wheel provided by the first preferred embodiment of the present invention is The carbon fiber body (4) and the metal connecting member 2〇 at both ends of the carbon fiber main body 10. The length of the carbon fiber main body 10 can be increased or decreased according to the size of the wheel; in addition, in the embodiment, the carbon fiber main body 10 is flat. Referring to the second figure, the metal connector 20 is provided with a threaded section 22. The threaded section 22 is combined with an axle (not shown) or a wheel frame (not shown), and in practice the connector can also be made The shape of the hook is not observable (not shown above is a prior art). The metal connector 2 is further provided with a head 24 and a retraction 26. The head 24 is located at one end of the metal connector and has an inner end. Connected to the hybrid section 26. In the present embodiment, the reduced diameter section 26 is - the flattened section 'and thus has at least one direction having a smaller diameter than the head 24. See the third figure, where a carbon fiber reinforced layer 30 is disposed on the reduced diameter section, and the carbon fiber The bonding layer 3() has the same outer diameter as the head portion. Referring to the third figure, the carbon fiber body 10 is composed of three fiber layers 1375627 I 101 05/08 曰 revised replacement pages 12, 14, and 16. The fiber 12 of the outer layer 12 is parallel to the long axis of the filament 1 to provide greater tensile strength. The fiber orientations of the other two inner layers 14, 16 are skewed at an angle to provide this angular orientation. a greater tensile strength. Both ends of the carbon fiber body 10 are coated with at least the head portion 24 and the carbon fiber bonding layer 30. Since the carbon fiber bonding layer 3 is the same material as the carbon fiber body 10, The bonding strength is large. If the spoke 1 is pulled by an external force, the carbon fiber bonding layer 3 is less likely to be separated from the carbon fiber main body 10. Moreover, due to the presence of the head portion 24, the carbon fiber bonding layer 30 does not escape from the metal connector 2〇. According to the experiments of the inventors, the spokes i provided by the first embodiment of the present invention can withstand a tension of at least 320 kg or more. Referring to Figures 4 and 5, the filament 2 of the second preferred embodiment of the present invention is also constructed of a carbon fiber body 4〇 and a two-metal connector 42. The difference is that, as shown in the fourth figure, the metal connector 42 has a reduced diameter section 44, and a second recess 6 is provided on the reduced diameter section 44. Referring to the fifth ' shown on the hybrid 44, a carbon fiber bonding layer 48 is also provided, which will enter the recesses 46 and have the same outer diameter as the metal connector 42. The carbon fiber main body 4 is also passed through the carbon fiber bonding layer 48 and the metal connecting member π. According to the experiment of the inventors, the second embodiment of the present invention can withstand a tension of at least 320 kg or more. The metal connector 2 is provided with a thread 52, a head portion 54, a coin 56' connected to the head portion, and a recess 58 provided on the diameter reducing portion 56. 5 1375627 101 〇 08 May 08 Revision Replacement Page By using the dual action of the head 54 and the recess 58 , the bonding strength between the carbon fiber main body and the metal joint can be greatly improved. According to the experiment of the inventor, this hair
