2. Description of the Related Art Conventional mudguards for vehicles include, for example, the one shown in Nissan Motor Co., Ltd. Service Bulletin No. 603, page D-27, published in 1988, and the one shown in FIGS. 3 and 4. In the figure, the end of the fender (vehicle body panel) 2 located behind the wheel 1 is bent at a substantially right angle toward the inside of the vehicle body to form a vertical flange portion 2a, and the lower end of the fender 2 is also bent at a nearly right angle toward the inside of the vehicle body. It is bent to form a horizontal portion 2b. On the other hand, the mudguard 3 is made of rubber-based resin, and includes a mounting part 4 provided in the vertical direction for mounting on the vertical flange part 2a, and a tongue-shaped mounting part 4 provided integrally from the lower end toward the inside of the vehicle body. It is formed from the guard part 5 and has an L-shape as a whole. This mounting part 4 has a U-shaped cross section, and the rear side wall 4a

It is attached through a screw insertion hole 4c formed in. In addition, the guard part 5 is located directly behind the wheel 1 with its upper end in contact with the lower surface of the horizontal part 2b of the fender 2, so that mud and pebbles thrown up by the wheel 1 are prevented from scattering onto the fender 2, etc. prevent. However, in the structure of such a mudguard, the guard part 5 is composed of a tongue-shaped single plate, and furthermore, the tip part of the guard part 5 on the inside of the vehicle body protrudes inward from the horizontal part 2b of the fender 2 and cannot be seen anywhere. Since it is not fixed, the strength of the guard portion 5 may not be sufficient. Therefore, Figure 5
It is conceivable to improve the strength of the guard part 8 by forming the guard part 8 into a bag structure like the mud guard 6 shown in FIG. That is, the guard part 8 and the mounting part 7 are integrated into an L-shaped front wall 6a and a rear wall 6b, and their outer sides and lower sides are joined to each other to form a U-shaped cross section. The inner ends are connected by an end wall 6c. Then, it is attached to the vertical flange portion 2a of the fender 2 via a screw insertion hole 7a provided in the attachment portion 7. In addition, a water drain hole 9 is provided at the center of the lower side of the guard portion 8.

[Problems to be Solved by the Invention] However, although the strength is increased by forming the guard part 8 into a bag structure, it is inevitable that rainwater and mud will enter through the upper opening of the guard part 8. . For this reason, a drain hole 9 is provided, but it is possible that this hole may become clogged. Further, since the drain hole 9 is provided at the center of the lower end, it may be visible from the rear of the vehicle and may spoil the appearance.

[0004] The present invention has been made by focusing on such conventional technology, and it is possible to ensure the strength of the guard portion without impairing its appearance, and to prevent rainwater and mud from entering and accumulating inside. The present invention provides a mudguard for vehicles.

[0005]

[Means for Solving the Problems] In order to achieve the above object, the vehicle mudguard according to the present invention includes a guard portion including a rear guard portion having a predetermined length toward the inside in the vehicle width direction; A front guard part that is shorter than the rear guard part and not longer than the horizontal part of the vehicle body panel is formed closer to the wheel than the rear guard part, and has a substantially U-shaped cross section that opens upward. The inner end and the middle part of the rear guard part corresponding to the inner end are connected by a vertical wall, and the upper end of the vertical wall and the upper end inside the middle part of the rear guard part are connected by a horizontal wall. They are connected.

[0006]

[Function] According to the vehicle mudguard according to the present invention, the rear guard part has a predetermined length inward, and the front guard part is shorter than the rear guard part and not longer than the horizontal part of the vehicle body panel. It has a roughly U-shaped cross section with an opening. For this reason, the part of the guard part on the mounting part side has a bag structure, and a vertical wall is provided at the inner end of the front guard part between it and the rear guard part to serve as a reinforcing material, ensuring strength. . Since the rear guard part is longer than the front guard part, it hides horizontal walls, vertical walls, etc. when viewed from the rear, and looks good from the rear. Furthermore, since the opening at the upper end of the bag-shaped portion is covered by the horizontal portion of the vehicle body panel, mud and rainwater are prevented from entering the interior. Only the rear guard part will protrude inward from the horizontal part, but since a horizontal wall is provided that spans the upper end of this rear guard part and the upper end of the vertical wall, the strength will decrease. can be suppressed.
