VI. Description of the Invention: [Technical Field] The present invention relates to a locomotive structure, and more particularly to a locomotive structure having an effect of improving the aesthetic appearance. [Prior Art] In general, current locomotives are usually equipped with reflectors for the purpose of improving safety. For example, in a conventional locomotive structure, a rear side reflector mechanism is typically attached to the exterior of a rear fender. Although the side reflector mechanism is then attached to the outside of the rear fender for improved safety, this practice affects the overall aesthetic appearance of the locomotive structure, thereby reducing the consumer's willingness to purchase. SUMMARY OF THE INVENTION The present invention basically employs the features detailed below in order to solve the above problems. That is, the present invention includes a frame; at least one wheel is coupled to the frame; a rear fender is coupled to the frame; an inner fender, ® is coupled to the frame, and is disposed on the frame Between the wheel and the rear fender; and a sheet of retroreflective sheeting attached to the inner fender and disposed between the wheel and the rear fender. Meanwhile, the locomotive structure according to the present invention further includes at least one stud bolt and at least one nut, wherein the stud bolt has a first threaded end and a second threaded end, and the first threaded end is via the inner end A fender is attached to the frame, and the second threaded end is locked to the nut via the set of reflective sheets. The above described objects, features and advantages of the present invention will become more apparent from the following description. [Embodiment] A preferred embodiment of the present invention will be described with reference to the drawings. Referring to FIG. 1 , FIG. 2 , FIG. 3 , and FIG. 4 , the locomotive structure 100 of the present embodiment mainly includes a frame 110 , a casing 120 , at least one wheel 130 , a rear fender 140 , and a rear The inner fender 150, a retroreflective sheet set 160, two stud bolts 170 and two nuts 180. As shown in FIGS. 1 and 2, the vehicle body 120 covers the frame 110. The wheel 130 is coupled to the frame 110. In the present embodiment, the wheel 130 is a rear wheel of the locomotive structure 100. The rear fender 140 is coupled to the frame 110. The inner fender 150 is also coupled to the frame 110, and the inner fender 150 is disposed between the wheel 130 and the rear fender 140. The retroreflective sheet set 160 is coupled to the inner fender 150, and the retroreflective sheeting set 160 is also disposed between the wheel 130 and the rear fender 140. Further, as shown in Figs. 2, 3, and 4, the retroreflective sheet set 160 has a disposing mechanism 161 and two reflecting sheets 162. Here, the retroreflective sheet set 160 is connected to the inner fender 150 by its arrangement mechanism 161. The two retroreflective sheets 162 are attached to the arrangement 161 and the two retroreflective sheets 162 are relative to each other. As shown in Fig. 3, each stud bolt 170 has a first threaded end 171 and a second threaded end 172. The first threaded end 171 is locked to the frame 110 via the inner fender 150, and the second threaded end 172 is locked to the nut 180 via the arrangement 161 of the retroreflective sheet set 160, such that the frame 110, The inner fender 150 and the retroreflective sheeting 160 can be locked together. 1374826 As described above, since the retroreflective sheet set 160 is disposed between the wheel 130 and the rear fender 140, the arrangement mechanism 161 of the retroreflective sheet set 160 is connected to the inner fender 150 and the retroreflective sheet set 160. The inner fender 150 and the rear fender 140 are covered, so that the appearance effect of hiding the arrangement mechanism 161 and exposing only the two reflecting sheets 162 can be obtained. Therefore, the overall aesthetic appearance of the locomotive structure 100 can be improved with both safety and security. Although the present invention has been disclosed in its preferred embodiments, it is not intended to limit the invention, and may be modified and modified without departing from the spirit and scope of the invention. Therefore, the scope of the invention is defined by the scope of the appended claims. 1374826 [Simple diagram of the diagram] • Partial stereoscopic combination of partial stereo decomposition One part of stereoscopic division - Partial stereoscopic group The first diagram shows one of the locomotive structures of the present invention; Figure 2 shows FIG. 3 is a schematic view showing the structure of the locomotive of the present invention; and FIG. 4 is a schematic view showing the structure of the locomotive of the present invention.
