用が得られるものである。As is well known, a cantilever brake device for a bicycle is a cantilever lever that is swingably supported by a cantilever on the front fork of the bicycle body, as shown in Fig. 1.
, fix the brake shoe (b) and tighten the cantilever lever (a).
) is rotated upward by the hanging wire (C), the brake shoe (b) presses into contact with the side surface of the rim of the wheel, thereby providing a braking action.

きさの装置が、取付位置を変更するのみで使用可能とな
る。This type of cantilever brake device has an advantage over a caliber brake device in which an arch is rotatably connected at the center in that there is no arch, so there is more flexibility in the mounting position. In other words, with a caliber brake device, the mounting position is limited, so the shape and size of the arch must be changed depending on the size of the bicycle, but in the book on the complete cantilever brake system, the shape and size of the arch are the same regardless of the size of the bicycle. The device can be used simply by changing the mounting position.
また、カンテイレバーブレーキ装置は、キャリパーブレ
ーキ装置のように片ぎきのおそれがなく、左右均尋な制
動力を得ることができると言う利点がある。Further, the cantilever brake device has the advantage that there is no risk of skidding, unlike a caliper brake device, and it is possible to obtain even braking force on the left and right sides.

精度が必要となり、調整が困難であった。On the other hand, the drawback of the cantilever brake device is that as the cantilever lever (a) rotates upward, the brake shoe (b) rotates downward, and the rim side surface (d) Because it is an inclined surface, the final pressing force is small, and excessive rotation can cause the brake shoe to
There was a high risk of the brake system slipping off the rim side surface (a), which required precision in the relative mounting position of the rim side surface and the brake device, making adjustment difficult.
