Description

[Detailed Description of the Invention] [Field of Industrial Application] The present invention relates to a throttle cable connection structure suitable for scooter-type motorcycles or tricycles, and particularly relates to a throttle cable connection structure that connects a throttle grip side portion and a carburetor side portion. This invention relates to improving the sealing performance of the connection part and the connection workability when configured with the following.

[Conventional technology]

Generally, scooter-type motorcycles and tricycles have an engine unit mounted at the lower rear of the vehicle body frame, and the carburetor of the unit and a throttle grip attached to a steering handle are connected by a throttle cable. On the assembly line for such scooter-type motorcycles and tricycles, one end of the throttle cable is pre-assembled to the carburetor of the engine unit by so-called sub-assembly.
This engine unit is generally mounted on the vehicle body.

Therefore, as a structure that enables such sub-assembly, conventionally, for example, the throttle cable is composed of a throttle grip side part and a carburetor side part, and the side parts are connected at a position below the footrest plate. There is a structure in which a waterproof cover consisting of a cylindrical boot made of rubber, for example, is attached to surround this connection part. In this conventional structure, since the connection is made at the lower position of the footrest, muddy water and the like are likely to splash onto this connection, so it is necessary to ensure high waterproofness. Therefore, in this conventional structure, a structure is adopted in which both the front and rear ends of the waterproof cover are closely fitted to both the front and rear ends of the connecting portion of the throttle cable.

[Problem that the invention seeks to solve]

By the way, in the above-mentioned conventional structure, when attaching the waterproof cover to the connecting part of the throttle cable, for example, the waterproof cover is first attached to the throttle grip side part of the throttle cable, and after connecting both sides of the cable via the connecting member, The waterproof cover is moved toward the carburetor so as to surround the connection member. However, in this case, the end of the waterproof cover is likely to get caught on the connection member, so although the conventional structure described above provides a waterproof effect, it is difficult to attach the waterproof cover to the connection part of the throttle cable, and as a result, the cable itself may be damaged. There was a problem of poor assembly.

SUMMARY OF THE INVENTION The purpose of the present invention was to solve these conventional problems by providing a scooter type that can improve the ease of assembling the connection part of the throttle cable while ensuring the sealing performance of the connection part. Automatic two.

The present invention provides a connection structure for a throttle cable for a tricycle.

[Means for solving problems]

The present invention provides a connection structure for throttle cables for scooter-type motorcycles and tricycles, in which the throttle cable is connected at the inner part of the leg shield arranged in the vertical direction, and the upper end is tightly fitted to the throttle cable at this connection part. together,
The lower end is characterized by a cylindrical cover member that is open to the cable.

[Effect]

In the connection part structure of the throttle cable for scooter-type motorbikes and tricycles according to the present invention, the lower end of the cover member is open with a predetermined gap from the cable, so that the cover member is attached to the connection part. In this case, the end of the cover member does not get caught on the connecting member, and it can be installed very easily, thereby improving the ease of assembling the throttle cable.

Further, although the lower end of the cover member is open,
Since the connection is made at a high position above the ground, the amount of water that enters this connection from below is extremely small compared to the bottom of the footrest, and water droplets that fall from above are placed vertically. Since the upper end of the cover member is in close contact with the cable, it can be reliably prevented, and as a result, sealing performance is ensured.
