By screwing or loosening the adjusting body 5, the lever 4 is swung through the abutment 43, and the distance between the finger hook 44 of the lever 4 and the handle A, that is, the grip It's like I'm making some adjustments to my schedule.

A cover 6 that covers the outer surface of the bracket 1 and the base of the brake lever 4 is attached to the bracket 1.

This cover 6 is made of a soft material such as rubber or soft synthetic resin, and has opposite side walls 61.
a, 61b, and a front wall 62, a rear wall 63, and an upper wall 64 that connect these side walls 61a, 61b, and has a grip-shaped outer shape,
The front wall 62 has a large number of protrusions 62 as shown in FIG.
a, 62a... to prevent the palm from slipping.

Further, a notch hole 65 is formed from the upper part of the rear wall 63 to the upper wall 64, and the brake lever 4 is made to protrude from this hole 65.
A locking portion 66 is integrally formed at the corner connecting the bracket 1 and the upper wall 64, and this locking portion 66 prevents the palm of the hand gripping the bracket 1 from slipping out.

On the other hand, one of the edges of both sides of the cover 6 facing to the side of the handle A, in other words, the edge of one side wall 61a constituting the cover 6 on the handle side is extended, and the tightening band 3 and the handle are extended. A wrapping portion 7 is formed to wrap around A. In the case shown in the drawing, the handle-side base of the cover 6 is extended in the front-rear direction, and the wrapping portion 7 is also extended along the length of the handle A in accordance with the base of the cover 6. It is being extended further.

The free end of the winding portion 7 and the other side wall 61
The handle side edge of b is brought into contact with the handle side edge as shown in FIG. Winding part 7
A plurality of insertion holes 67, 67, . . . and 71, 71, . The free end is detachably fixed to the cover 6.

In the figure, reference numeral 81 denotes an operating wire 8 which is swingably supported on the pivot portion 42 of the brake lever 4.
The locking fitting 82 is an outer cylinder for guiding the wire 8, one end of the cylinder 82 is supported by the support 24 inserted into the engagement hole 23 of the adapter 2, and the other end is supported by the cover 6. It is guided to the outside through a groove 73 formed on the inner wall surface of the winding portion 7 .

The present brake operating device is constructed as described above, and when the bar tape is wrapped around the handle A after this device is attached to the curved rod portion B of the handle A, the tightening band 3 and the brake on the handle A are attached. Since the mounting part of the operating device is covered by the winding part 7 of the cover 6, it is sufficient to wrap the bar tape up to the ends 7a, 7a on both sides of the winding part 7, as in the conventional case. There is no need to wrap the handle A up to the attachment part of the brake operating device.

Moreover, the cover 6 is provided with a wrapping portion 7,
Since the handle A is worn while hugging the handle A, even when the cover 6 covering the bracket 1 is gripped to operate the handle and the brakes, the wrapping portion 7 integrally formed on the cover 6 is attached to the handle A.
