It shows a fixed state.

Below the rear wheel mudguard cover 11a and the front wheel mudguard cover 11b (hereinafter, both are collectively referred to as “mudguard cover 11”), a cover side engaging portion 13 for engaging with the mudguard stay 12 is provided. As a result, in the mudguard cover 11 having a U-shaped cross section, engaging insertion holes 13a are formed in the portions corresponding to the U-shaped bottom portion, and engaging concave portions 13b for engagement are formed in the portions corresponding to the U-shaped ends. ing.

The mudguard stay 12 is common for the front wheels and the rear wheels. The mudguard stay 12 is a U-shaped wide strip, and has hub axle mounting portions 16 for fixing the mudguard cover 11 to the vehicle body at both ends of the U-shape, and a mudguard cover at the central bottom of the U-shape. 11 has a stay side engaging portion 15 which is a cover attaching portion for engaging and fixing with 11. The hub shaft mounting portions 16 at both ends are provided with screw holes 16a for mounting to the hub shaft. The stay-side engaging portion 15 is provided with convex portions 15a and 15b at positions corresponding to the engaging insertion hole 13a and the engaging concave portion 13b, which are the cover-side engaging portion 13. The convex portion 15a is fitted and inserted in the insertion hole 13a, and the convex portion 15b is locked in the concave portion 13b.

The portion from the hub shaft mounting portions 16 at both ends to the cover side engaging portion 15 (hereinafter, referred to as “stationary body portion 17”) may be a simple strip, but the length is adjusted. It is preferable to have a structure that can be present. As the adjustable structure, a conventionally known appropriate means is used. For example, as shown in FIG. 4, a member 18 for attaching a hub axle having an elongated hole 18a and a cover attaching portion having a plurality of screw holes 19a so that the length of a stay body 17 can be changed. A configuration in which the side member 19 and the side member 19 are combined is included. FIG. 4A shows a state before combination, and FIG. 4B shows a state after combination. In FIG. 4, 20 is a screw.

The mudguard devices 10 a and 10 b (hereinafter, both are collectively referred to as “mudguard device 10”) configured as described above are configured such that the convex portion 15 a, which is the stay side engaging portion 15 of the mudguard stay 12, is attached to the mudguard cover 11. The protrusion 15b may be fitted into the insertion hole 13a, the protrusion 15b may be locked in the engagement recess 13b of the mudguard cover 11, and then the hub axle mounting portion 16 may be attached to the hub axle.

As described above, since the mounting and fixing work of the mudguard cover 11 and the mudguard stay 12 is performed by fitting the concave and convex portions that are the engaging portions of both parties, various types of clamping plates, screws, etc. can be used as in the past.

On the other hand, since the mudguard stay 12 is a wide strip-shaped object, the areas required for stable engagement and fixing can be secured for the convex portions 15a and 15b as the stay engaging portions 15. Therefore, the number of parts is smaller than in the past, and the mounting work is simplified. Further, when the mudguard cover 11 and the mudguard stay 12 are made of synthetic resin, various decorations such as not only the same color but also a combination of different colors are possible, which is excellent in terms of design.

Further, by making the length of the stay main body portion 17 adjustable, it is only necessary to produce one kind of mudguard station 12 for bicycles having different sizes such as 14 inches, 16 inches, 18 inches. Is enough. This means that when the mudguard stay 12 is made of synthetic resin, only one type of mold is required, and thus the production cost can be reduced.

In the above embodiment, the cover-side engaging portion 13 is the insertion hole 13a and the concave portion 13b, and the stay-side engaging portion 15 is the convex portions 15a and 15b, but the cover-side engaging portion 13 is convex. The stay side engaging portion 15 may be concave. Further, the mounting portion of the mudguard stay 12 in the mudguard cover 11 is provided below the mudguard cover 11 in the above embodiment, but the present invention is not limited to this position, and the mudguard cover 11 can be stably mounted on the vehicle body.

The cargo basket 31 and its mounting method will be described with reference to FIGS. 6 and 7. The luggage basket 31 has an engaging hook 35 at the opening edge of the upper end thereof, and a long hole 37 is formed in the side surface 36 on the side where the engaging hook 35 is attached. On the other hand, the cargo basket mounting member 32 has a locking hole 38 formed therein for locking the engagement hook 35 of the cargo basket, and a lamp mounting portion 39 below. The engaging hook 35 of the cargo basket 31 is hooked in the locking hole 38, and the side face 36 of the cargo basket 31 is fixed to the lamp mounting portion 39 via the long hole 37 with the screw 40.

On the other hand, conventionally, as shown in FIG. 8, the bottom surface 8a and the side surface 8b of the cargo basket 8 are screwed at two positions. Therefore, according to the cargo basket 31, since the number of screwed portions is reduced by one, the mounting work is easy, and since the screw portion on the bottom surface is eliminated, the object accommodated in the cargo basket 31 is screwed on the bottom surface. There is also an effect that it will not be damaged by.
