Description

[Detailed Description of the Invention] The present invention relates to a side grip ξj, 1J111IjK'□, which is installed at the rear of a motorcycle and is used to grip the rear part of a heavy body when the main stand is raised, etc. be.

When riding a large motorcycle, hold the main stand when a heavy person stands up, and hold the rear part of the heavy person.
However, side grips are provided for rear seat occupants.
．． (Also used, such side grips are generally provided at the rear of the functional i body frame 4).

On the other hand, the Freno/rear part of a motorcycle has its main roots.
Extends rearward from the rear of the member 5. The upper pipe that forms the seat rail, the main roots, and the center pipe that hangs downward from the rear of the member extends diagonally to one side from the rear part 1-IX, and is arranged diagonally with the middle part and tip of the upper pipe joined. It consists of 1, Nriguchikogu.

In the conventional rear part of such a frame, the tip of the subtube is joined to the middle part of the upper pipe, so the part of the upper pipe behind the joint is long (), [su, overhanging state, and here the part of the previous i1 In order to provide side grips that are subject to loads, it is necessary to increase the rigidity.

In order to prevent bending, it is necessary to add a reinforcing member or increase the pipe diameter of the frame member.
According to this, Freno's BF f? If the frame structure becomes complicated, there are disadvantages such as complicated manufacturing and an increase in the number of components.

The present invention has been devised in view of the above, and its objectives and points are as follows: The rear end of the subtube is joined to the vicinity of the rear end of the upper pipe, and brackets are provided on the front and rear sides of the joint. A side grip support structure is provided in which several front and rear ends of the side grip are supported, and the side grip is highly rigid and can sufficiently support the load applied to the lead grip. [Excellent rigidity and strength while providing a grip] I-Freno has a simple structure, is easy to manufacture, and is lightweight. 1.2 The side grip support structure in the automatic wheel is provided in the J-7.

The rib tube 207 is long, and its rear end 207b is joined to the rear of the upper pipe 206 as far as possible. From ``2'', the Freno rear part B is the component part. Specifically, this joint portion 208 is set to 7/i as follows.

Sea 1.11 is a two-seater Kawa Tandeno or Note.The front seat 111 faces the middle or front part of the upper pipe 206 behind the fuel tank 10, and the rear seat 11 is continuous with the front seat.

On the other hand. Furthermore, the rear wheel 131 is facing the Murya Huenda 15.
In the vicinity of the middle part 15a which is located at the highest point r't of the curved part of A), it is located rearward of the middle heat part in the front-rear direction.

In this way, the rear end 207b of the sub tube 207 is as close as possible to the rear end of the upper pipe 2060.

No, 2A! The overhang area for descending and descending is reduced by 7F, and the IMI at the rear of the frame is reduced by the long truss structure from front to back.
I+ 1'Ig is the direction 1-shi, so the stiffness of the upper pipe amplifier! However, it is possible to reduce the number of frame components, simplify the frame, facilitate manufacturing, and further reduce the weight. The rectangular space surrounded by the center pipe 204, upper pipe 206, and sub tube 207 becomes large, and there are, for example, an air cleaner 16, a mail tank 17, and a battery 18. This embodiment employs a water-cooled engine, so a reservoir/reservoir is installed. 19 etc. can be stored all at once, and the capacity of these old devices can be set larger.
