In this example, the power unit 103 is swingably mounted vertically on the rear portion of the vehicle body frame, and the rear wheel 104 is supported on the rear end portion thereof. A rider seat 105 and a pillion seat 106 are continuously provided from the center to the rear of the vehicle body, and the entire vehicle body is covered by a cowling 107 which is an exterior.

FIG. 2 is a cross-sectional view showing the periphery of the grip end of the handle 10 according to the outer weight mounting structure for a handle of the present invention. As shown in FIG. 2, the outer weight 11 is attached to the tip of the handle 10. In this case, the outer weight 11 is inserted into the tip of the handle pipe 12 and has a cylindrical shape with a screw hole 13 for screwing the handle weight 11 to the inner circumference. The spacer 14 is provided. Through holes 16 and 17 for the bolt 15 are formed in the outer weight 11 and the spacer 14, respectively, and a screw portion 18 of the bolt 15 inserted into the through hole 16 and 17 is screwed into the screw hole 13 of the spacer 14. A grip rubber 19 fixed by an adhesive is attached to the outer periphery of the handle pipe 12.

The spacer 14 has a flange portion 14a having substantially the same diameter as the outer diameter of the handle pipe 12, and the handle pipe 12 and the spacer 14 both have through holes 20 and 21 formed so as to penetrate through them in the radial direction. Then, the spacer 14 is locked and fixed by the locking pin 22 inserted into these through holes 20 and 21.
The gripping rubber 19 is attached to the outside of the locking pin 22 in the handle pipe 12 and the spacer 14 in the radial direction, and the inside of the locking pipe 22 is attached to the screw hole 13 by a bolt 15 which is screwed into the screw hole 13. That is, one end of the locking pin 22 contacts the inner peripheral surface of the grip rubber 19, and the other end of the locking pin 22 contacts the outer peripheral surface of the bolt 15.

An elastic cushion 23 made of, for example, rubber is disposed between the outer circumference of the spacer 14 and the inner circumference of the handle pipe 12, and the locking pin 22 is tightly fitted into the through hole 24 formed in the elastic cushion 23 in the radial direction. Insert it. The elastic cushion 23 has a flange portion 23a having substantially the same diameter as the outer diameter of the flange portion 14a of the spacer 14.

The through hole 21 of the spacer 14 has substantially the same diameter as the locking pin 22 and is formed so that the locking pin 22 can be inserted and removed without rattling. The through hole 20 of the handle pipe 12 is formed to have a larger diameter than the through hole 21 of the spacer 14.

Next, FIGS. 3A to 3C show an assembling procedure of the outer weight 11 in the outer weight mounting structure according to the present embodiment.
In FIG. 3A, the elastic cushion 23 is attached to the spacer 14, and the locking pin 22 is inserted into the through hole 21 of the spacer 14 and the through hole 24 of the elastic cushion 23. In this temporarily assembled state, one end of the locking pin 22 is prevented from projecting from the outer peripheral surface of the elastic cushion 23. In this case, the locking pin 22 is tightly inserted into the through hole 24 of the elastic cushion 23, so that the locking pin 22 is tightly inserted. 22 is prevented from falling off.

The spacer 14 and the elastic cushion 23 in the temporarily assembled state are inserted into the inner circumference of the handle pipe 12 as indicated by the arrow. In this case, since one end of the locking pin 22 does not project from the outer peripheral surface of the elastic cushion 23, the locking pin 22 is smoothly inserted without being caught by the end of the handle pipe 12, and the locking pin 22 falls off. No worries.

In FIG. 3B, the elastic cushion 23 in the temporarily assembled state is inserted into the inner periphery of the handle pipe 12 until the flange 23 a of the handle pipe 12 abuts against the end of the handle pipe 12. In this case, the other end of the locking pin 22 projects into the screw hole 13 of the spacer 14 as shown in FIG. 3A, but one end of the locking pin 22 is formed through the through hole of the handle pipe 12 using the work rod 200. It is pushed in until it reaches 20. This prevents the other end of the locking pin 22 from protruding into the screw hole 13 of the spacer 14.

In FIG. 3C, the bolt 15 is inserted into the through hole 16 of the outer weight 11 and further inserted into the through hole 17 of the spacer 14, and the screw portion 18 of the bolt 15 is screwed into the screw hole 13 of the spacer 14. In this case, since the other end of the locking pin 22 is retracted from the screw hole 13 of the spacer 14, it does not interfere with the screw portion 18 of the bolt 15.

In the outer weight mounting structure according to the present embodiment, the outer weight 11 is assembled by the above procedure and mounted on the tip of the handle 10 as shown in FIG. Since the elastic cushion 23 is mounted between the handle pipe 12 and the spacer 14, the outer weight 11 is elastically supported by the tip of the handle 10. According to the outer weight 11 as described above, a high vibration damping effect is obtained as a dynamic damper that reduces engine vibration, and comfort when the motorcycle 100 travels is ensured.

According to the present invention, in particular, when the spacer 14 is locked to the handle pipe 12, the locking pin 22 is operated from the screw hole 13 of the spacer 14 so that the grip rubber 19 remains attached to the outer periphery of the handle pipe 12. It becomes possible to assemble them in the state of. As a result, the flexibility of the assembly procedure is increased, the number of assembly steps can be reduced, and the assembly cost can be reduced.

As described above, the elastic cushion 23 is mounted between the inner circumference of the handle pipe 12 and the outer circumference of the spacer 14, and the locking pin 22 is tightly inserted into the through hole 24 of the elastic cushion 23. A temporary fixing (prevention of falling) function is secured. As a result, the assembly work can be carried out smoothly and accurately, and the workability can be improved.

Further, the through hole 21 of the spacer 14 is formed so that the locking pin 22 can be inserted and removed without rattling, while the through hole 20 of the handle pipe 12 is formed to have a larger diameter than the through hole 21 of the spacer 12. This allows the spacer 14 to move due to the deformation of the elastic cushion 23, prevents the locking pin 22 from tilting at the worst when the locking pin 22 is inserted, and prevents the locking pin 22 from falling off at the worst. Can be done to.

Here, the tip portion of the bolt 15 for fastening and fixing the handle weight 11 may be formed in a tapered shape. The other structure is substantially the same as that of the above-mentioned embodiment.

The spacer 14 and the elastic cushion 23 in the temporarily assembled state are inserted into the inner circumference of the handle pipe 12 as shown in FIG. 3A, and then the bolt 15 is inserted into the through hole 16 of the outer weight 11 as shown in FIG. 3C. Further, it is inserted into the through hole 17 of the spacer 14. When the screw portion 18 of the bolt 15 is screwed into the screw hole 13 of the spacer 14, even if the other end of the locking pin 22 projects into the screw hole 13 of the spacer 14, the inclination of the tapered tip end portion of the bolt 15 is increased. The surface can surely push the other end of the locking pin 22 into the through hole 24.

The outer weight 11 can be assembled by simply screwing the screw portion 18 of the bolt 15 into the screw hole 13 of the spacer 14 without using the work rod 200 shown in FIG. It is possible to improve efficiency.

In the second embodiment of the outer weight mounting structure of the present invention, the end portion of the spacer 14 is extended inward of the handle pipe 12. FIG. 4 is a sectional view showing the vicinity of the grip end of the handle 10 in the second embodiment of the outer weight mounting structure for a handle of the present invention.
As shown in FIG. 4, a solid extension 25 to the left of the screw hole 13 is arranged in the handle pipe 12. A cushion 26 is attached near the end of the extension portion 25 as needed.

In the second embodiment, the extension 25 functions as a handle weight, that is, the extension 25, in combination with the outer weight 11, increases the weight of the handle weight without changing the width of the handle 10. By increasing the handle weight in this way, the vibration damping effect can be further effectively improved. By providing the cushion 26, the extension portion 25 is properly supported in the handle pipe 12, and it is possible to prevent generation of abnormal noise due to contact between the extension portion 25 and the inner surface of the handle pipe 12.
