Description

[Detailed Description of the Invention] (Technical Field) The present invention relates to a mounting structure for a master cylinder attached to a handle pipe of a motorcycle, a tricycle, etc.

(Prior technology) It is attached to the handle pipe of motorcycles, tricycles, etc., and generates hydraulic pressure in conjunction with the operating lever.
A master cylinder that performs brake operation, etc. generally consists of a cylinder body and a reserve tank.
In the case where a handle cover covering the handle pipe is attached, the grip and operating lever protrude from the opening at the end of the handle cover, but the master cylinder is covered with the handle cover together with the handle pipe. Therefore, in motorcycles, tricycles, etc. equipped with handle covers, when checking the oil level in the reserve tank, the handle cover must be removed each time, making it difficult to check the oil level easily and quickly. Ta.

(Purpose of the invention) The present invention has been devised in view of the above-mentioned circumstances, and the purpose of the present invention is to provide a master cylinder mounting structure that allows easy and quick oil level inspection work. It is in.

(Structure of the invention) In order to achieve the above-mentioned object, the present invention forms the oil level visualizing part of the reserve tank facing the opening side of the handle cover, and provides lighting so that light can be taken into the oil level visualizing part in the handle cover. A special feature is that the oil level can be checked simply and quickly from the opening of the handle cover without removing the handle cover.

(Embodiment) Hereinafter, a preferred embodiment of the present invention will be described with reference to the accompanying drawings.

FIG. 1 is a side view of the motorcycle, FIG. 2 is an enlarged side view of a handle cover portion, and FIG. 3 is a plan view of the same.

1a is the front wheel, 1b is the rear wheel, 2 is the leg shield, 3 is the handle pipe, 4 is the handle cover,
5 is a meter visor, and the handle cover 4 consists of a front cover 4a that covers the handle pipe 3 and a rear cover 4b. The front cover 4
A headlight 6, turn signal 7, etc. are installed in the rear cover 4b, and various meters 8 such as a speedometer are installed in the central opening of the rear cover 4b.

A throttle grip 11 and a front wheel brake lever 12 are disposed at the right end of the handle pipe 3, respectively, and the throttle grip 11 and brake lever 12 protrude from an opening 13 at the right end of the handle cover 4.

A throttle case 21 is attached to the three handle pipes on the inside of the throttle grip 11, and a boss portion 22 for attaching a back mirror is integrally formed on the throttle case 2, and the back mirror attaching portion 22a is attached to the handlebar. The rear mirror 2 is attached to the upper surface of the cover 4 through the mounting portion 22a.
Install 3.

At three locations of the handle pipe inside the throttle case 21, a reserve tank 32 is provided upright from the cylinder body 31, as shown in the arrow direction view in FIG. 3 and in FIG. 4 and FIG. 5, respectively. A master cylinder 33 is attached to the front of the handle pipe 3 via a bracket 34, and the base of the brake lever 12 is attached to the master cylinder 33 via a support shaft 35.

The reserve tank 32 is formed horizontally and has a scale portion 41 for visually confirming the amount of oil in the reserve tank 32.
is formed on the opening 13 side so that the scale portion 41 can be visually recognized from the opening 13 side. 42 in the drawing
43 is the upper level, 43 is the lower level, and 44 is the cap.

The handle cover 4 above the master cylinder 33 has an opening 51 having a predetermined longitudinal and lateral width.
The opening 51 is covered with a detachable cap member 53 via a screw 52.

The cap member 53 has a continuous top surface portion 53a on the top surface of the handle cover 4, and a side surface portion 4b that is bent from the top surface portion 53a and continuous on the side surface of the handle cover 4.
Equipped with. The scale portion 4 is provided on the cap member 53.
A transparent daylighting window 61 made of transparent resin is formed from the top surface 53a above the opening 13 of 1 to the side view 53b, and external light is introduced into the handle cover 4 from the daylighting window 61 into the scale section. The area around 41 is formed to be bright.

Since this embodiment is configured as described above, when checking the oil level in the reserve tank 32, although the reserve tank 32 is covered with the handle cover 4, the scale part 41 is brightly illuminated by light from the daylighting window part 61. Therefore, when checking the oil level in the reserve tank 32, the oil level can be easily checked from the opening 13 at the height of the handle 3 without removing the handle cover 4.
It can be done quickly.

(Effect of the invention) As is clear from the above explanation, according to the invention,
Inspection of the oil level in the reserve tank can be performed easily and quickly.
