つていた。 Generally, the mudguard 2' is supported at two points as shown in Fig. 1, one point is attached to the frame 7 with the mounting bracket 6', and the other point is the stay 9'.
It is supported by (The figure shows the rear wheel part, but the same applies to the front wheel part.) However, in the conventional mounting structure, as shown in Figs. 2 to 4, the mounting bracket 1' and the mudguard 2' are is rivet 1
1, and on the other hand, the stay mounting bracket 8', which has a square cross-section, is tightened with screws 12 and nuts 13 for the stay 9' and mudguard 2', so that an amateur cannot attach the mudguard to the bicycle body after purchase. Dodge 2'
It was not possible to easily attach and detach the bicycle without using tools or disassembling it, and as a result, bicycles were sold that were equipped with only the minimum necessary parts for riding, and after purchase, amateurs were unable to install or remove them without using tools or disassembling them. When attempting to manufacture a so-called optional bicycle in which the attached parts of the bicycle are optionally attached, the mounting structure of the mudguard 2' remains a technical issue.

ねじ２８にてフレーム７に固定する。 Reference numeral 2 in FIG. 5 is a mudguard, in which steps are provided on one side of the mudguard 2 at appropriate locations with the slit hole 14 as a boundary to form a concave curved portion 15, and the other is provided with a step to form a convex curved portion. It is set as 16. Reference numeral 1 denotes a clamping piece made of spring steel. A rivet hole 17 is bored at the base end of the clamping piece 1, and the tip is bent into an L shape to serve as a retainer 18. The engaging portion 4 is concavely curved, and an engaging hole 4a is bored near the tip. Then, this clamping piece 1 is stacked on the back side of the mudguard 2 with a gap 19 provided in the convex curved part 16, and the base end is fixed to the mudguard 2 by caulking with a rivet 20, and in this way, the clamping part 3 is fixed. It is configured. Reference numeral 6 denotes an L-shaped mounting piece, which is attached to the frame 7 with screws 21. Of the mounting piece 6, a dodging side piece 6a protruding from the frame 7 has an engaged portion 5 at its tip and a second engaged portion 5a at its intermediate portion. Therefore, when attaching the mounting piece 6 to the mud guard 2, as shown in FIG.
is positioned in the concave curved part 15 of the mud guard 2, and then slid to the side of the clamping part 3 so that it is clamped between the protruding part 16 and the clamping piece 1, and at this time, the engaging part 4 and the engaging part The hole 4a engages with the engaged portion 5 and the second engaging portion 5a, respectively. Furthermore, when removing the mud guard 2, the mud guard 2 is pulled in the opposite direction to remove the mud guard side piece 6a of the mounting piece. Numeral 27 is a through hole drilled in the mounting piece 6, and is fixed to the frame 7 with a screw 28 through the through hole 27.

２３に必ずしも限定されるものではない。 Reference numeral 8 denotes a stay mounting piece made of spring steel, which has a rivet hole 17 drilled at its base end, and the tip of the stay mounting piece 8 is curved into a hook-shaped portion 8a.
This stay attachment piece 8 is connected to the back side of the mud guard 2 by caulking with a rivet 20, and the hook-shaped portion 8a projects outward from the through hole 22 of the mud guard 2. Reference numeral 9 denotes a stay made of wire bent into a U-shape, and the bent portion 10 of the stay 9 is press-fitted into the hooked portion 8a, and the bent portion 10 is elastically gripped by the hooked portion 8a. 23 is a stay support for detachably attaching the tip of the stay 9 to the axle side, and is composed of a cylindrical part 24 and a ring-shaped fixing part 25, and this fixing part 25 is rotatably attached to the axle part 26. It has been. Therefore, the tip of the stay 9 is inserted into the cylindrical part 24 of the stay support 23, and then the stay mounting bracket 23 and the stay 9 are rotated around the wheel part 26, and the bent part 10 of the stay 9 is hooked. Press fit into the shaped portion 8a. Moreover, when removing the mud guard 2 from the stay 9, the reverse operation may be performed. Note that the means for removably attaching the stay 9 to the axle portion 26 is not necessarily limited to the stay support fitting 23.

う効果を奏する。 As described above, the present invention includes stacking a clamping piece formed of a spring plate on the mudguard, and fixing the base end of the clamping piece to the mudguard to form a clamping part at an appropriate location on the mudguard, A concave or convex engaging portion is provided on the overlapped surface of the clamping portion, a mounting piece having a convex or concave engaged portion is protruded from the frame, and the mounting piece is removably clamped on the clamping portion and engaged. Since the part and the engaged part are engaged, the mounting piece can be inserted into the clamping part, and after insertion, the spring force of the clamping part and the engagement of the engaging part and the engaged part are used. It will not come off carelessly. On the other hand, the stay mounting piece, which is a hook-shaped spring plate, protrudes from the doroyoke, and the bent part of the U-shaped stay, whose one end is removably attached to the wheel part, can be freely attached to and detached from the stay mounting piece of the doroyoke. Since the stay is inserted into the bracket, the stay can be attached and detached from the mudguard due to the spring deformation of the stay mounting piece, and after installation, the stay can be accidentally removed due to the hook-shaped shape of the stay mounting piece and the spring force. Things will go away. As a result, it has become possible to install and remove mudguards without using tools or disassembling the bicycle, making it possible to manufacture optional bicycles, which will fully meet the demands of the new era of bicycles. It has the effect of becoming.
