ツ１５が設けられている。 As shown in FIGS. 1 to 3, the conventional master cylinder has lever bolt holes 3a and 3b drilled in the upper arm 2a and lower arm 2b of the operating lever mounting portion 2 formed in a forked shape on the master cylinder body 1, This upper arm 2
Insert the operating lever 4 between the upper arm 2a and the lower arm 2b, pass the lever bolt 5 through the hole 3a of the upper arm 2a, the lever bolt hole 4a of the operating lever 4, and the hole 3b of the lower arm 2b. It is screwed onto the operating lever mounting portion 2, and the operating lever 4 is rotatably supported by the lever bolt 5. Further, a mirror boss portion 9 for attaching a side mirror 8 is specially provided integrally with the master cylinder body 1, and a side mirror mounting shaft 11 is screwed into a hole 10 formed in the boss portion 9.
A side mirror mounting shaft 11 was fixed to the boss portion 9 by a nut 12. By operating the operating lever 4, a piston 14 provided within the cylinder 13 is pushed to generate hydraulic pressure, and a boot 15 is provided between the piston 14 and the cylinder 13.

廻りにくいなどの問題点があつた。 In the master cylinder for a two-wheeled vehicle configured in this way, the operation lever mounting part 2 and the mirror boss part 9 are separately molded on the master cylinder body 1, which increases manufacturing costs and also makes it difficult for the side mirror mounting shaft 11 to Mirror boss part 9 to be attached
In order to prevent the side mirror mounting shaft 11 from swinging while driving, the master cylinder must be formed large and long, which results in a large and heavy master cylinder, and when the master cylinder body 1 is cast using a mold. There were problems such as difficulty in circulating hot water to the mirror boss portion 9.

操作レバー４を回動自在に支持する。 First, an embodiment shown in FIGS. 4 and 5 will be described. The operating lever mounting portions 2 of the master cylinder body 1 are formed on the upper arm 2a and the lower arm 2b, and the side mirror mounting shafts are formed on both arms 2a and 2b. hole 16
Drill holes a and 16b. The operating lever 4 is arranged between the upper arm 2a and the lower arm 2b, and a side mirror mounting shaft 17 consisting of a single support shaft having a side mirror at the upper end and a bolt at the lower end is used to attach the side mirror to the upper arm 2a from above. It passes through the shaft hole 16a and the lever bolt hole 4b of the operating lever 4, and the bolt is screwed into the side mirror mounting shaft hole 16b of the lower arm 2b. Then, hold the washer 18 and screw the nut 19 onto the bolt to secure the side mirror mounting shaft 17 to the operating lever mounting portion 2, and mount the side mirror mounting shaft 17 upright to the operating lever mounting portion 2. The operating lever 4 is rotatably supported.

マスタシリンダボデイ１から外れない。 In the embodiment shown in FIG. 6, a metal bushing 21 is inserted into the lower end of the side mirror mounting shaft, and an operating lever 4 is rotatably provided on the bushing 21.
The metal bush 21 is the upper arm 2 of the operating lever mounting part 2.
Since it is provided extending from a to the lower arm 2b, the operating lever 4 will not come off from the master cylinder body 1 even if the side mirror mounting shaft is removed.

く、安価に成形できる。 Next, the operation of the present invention will be described. The side mirror mounting shaft 17 is attached to the upper arm 2a of the operating lever mounting portion 2.
The operating lever 4 and the side mirror mounting shaft 17 can be easily attached by simply fastening a nut 19 to the side mirror mounting shaft holes 16a and 16b of the upper arm 2a and the lower arm 2b. The side mirror mounting shaft 17 is supported by the upper arm 2a and the lower arm 2b, and since the length between them is relatively wide, the supporting force is strong.
Even if the mirror 7 is subjected to circumferential vibration, the holding force is sufficient, allowing the driver to check the rearward field of view through the side mirror without any blurring. Moreover, since the side mirror mounting shaft 17 is attached to the operating lever mounting portion 2, there is no need to mold the mirror boss portion 9 for fixing the side mirror mounting shaft 17 to the master cylinder body 1, which allows for a reduction in size and weight. Furthermore, even if the master cylinder body 1 is cast in a mold as in the conventional case, there is no problem such as the molten metal not flowing easily through the mirror boss portion, and the master cylinder body can be molded at low cost.

性の向上が図られる。 In addition, since the side mirror mounting shaft and lever bolt are connected to a single support shaft, compared to a case where the side mirror mounting shaft is mounted to the lever shaft with a screw, there is only one threaded part, so there are only two threaded parts. It is possible to effectively prevent the side mirror from wobbling as there is less bolt loosening compared to other products, and the number of parts is also reduced.Furthermore, by simply fastening the side mirror mounting shaft with a nut, both the side mirror and the operating lever can be easily fixed. can be installed reliably, and only needs to be assembled in one place, improving work efficiency.

される。 As explained above, according to the present invention, the side mirror and the operating lever are supported by the side mirror mounting shaft, and the mounting structure is simple and reliable, and the ease of installation is improved. The side mirror mounting shaft that supports the mirror and the operating lever is supported by the upper and lower arms of the operating lever mounting part and is mounted upright on the operating lever mounting part, so the length of the steady rest by the upper arm and lower arm is reduced. Since the vehicle is securely supported, even if the vehicle vibrates, circumferential vibrations occurring in the side mirror mounting shaft are reliably prevented, and blurring of the rear view due to the side mirrors during driving is effectively prevented.
