In addition to surrounding the handlebar with a handlebar cover,
A mask cylinder of a hydraulic brake and its reserve tank may be disposed within the handle cover. Conventionally, the arrangement structure inside the handle cover of this reserve tank was
For example, by making the reserve tank protrude from the handle cover,
There is a structure in which the protrusion is covered with a cap member and the cap member is attached to a handle cover (see, for example, Japanese Utility Model Publication No. 1986-1938).

[Problem that the invention seeks to solve]

However, in the conventional handle cover described above, the attachment portion of the cap member to the handle cover is exposed to the outside, and the attachment portion deteriorates the overall appearance of the handle cover.

There is also the problem that this cap member disturbs the flow of the running wind, resulting in running wind resistance.

On the other hand, if the reserve tank is covered with a handle cover that has a continuous and smooth shape, the protrusion caused by the cap member can be avoided, but there is a problem that the handle cover itself becomes large, and the reserve tank The oil level display scale on the tank becomes difficult to read.

The present invention has been made to solve the above-mentioned conventional problems, and provides a handle cover for motorcycles and tricycles that can avoid deterioration of appearance, increase in wind resistance, and increase in force TSL, and also has an easy-to-read oil level display scale. is intended to provide.

[Means for solving problems]

In the present invention, the hydraulic brake reserve tank attached to the handlebar is tilted diagonally downward from the front and diagonally downward from the rear from the top.

In a handle cover for a motorcycle or tricycle covered by an upper cover part having a cross section having a rearward slope, a part of the rearward slope is substantially continuous with the top part of the rear side slope. The tank accommodating part is integrally formed with a bulge,
The reserve tank is located within the tank accommodating portion, the rear wall of the tank accommodating portion is aligned with the rear surface of the reserve tank, and an opening is provided in a portion of the rear wall corresponding to the oil level display scale of the reserve tank. It is characterized by

[Effect]

According to the handle cover for a motorcycle or tricycle according to the present invention, a part of the rear inclined surface is bulged out so as to be substantially continuous with the top part to form a tank accommodating part, and a reserve tank is positioned within the tank accommodating part. As a result, it is possible to avoid deterioration in appearance as in the case of the conventional structure covered with a cap member protruding from the handle cover, and the air resistance is also small, avoiding the problem of increased running wind resistance.

Further, since the reserve tank is arranged using the highest portion of the handle cover, the amount of protrusion of the tank accommodating portion can be reduced, and it is possible to avoid increasing the size of the handle cover as a whole.
