[Detailed Description of the Invention] (Technical Field) A gear change operation device mainly used for rotating east, specifically, a control lever rotatably supported on a fixed member via a lever shaft, The present invention relates to a speed change operation device in which a transmission is actuated by operating the lever.

(Prior art) In general, this type of gear shift operation device, when switching the transmission to a predetermined gear position by rotating the operating lever, rotates the operating lever to an appropriate position corresponding to the gear position. However, in a shift operating device in which the operating lever is provided with a friction mechanism that provides resistance that overcomes the return spring of the transmission, it is difficult to operate the operating lever to the appropriate position. Generally, an overshift is performed, and the driver senses by the feel of the pedaling foot that the chenno has engaged with the desired sprocket, and then operates the lever to adjust the amount corresponding to the overshift.

However, this operation not only requires skill, but also requires the use of a lot of nerve in the shift operation. The time it takes to take your hands off the bike becomes longer, and when you change gears, you lose a lot of time when you can't concentrate on driving and steering the bicycle, especially in road races. There was a problem that occurred.

However, for the problem of [1, te d, the shift operating device has a positioning section H having a retaining section corresponding to the main shift stage of the transmission, and +1rTFi1. ! , a positioning mechanism for the lever comprising an engaging body that switches and engages with the retaining portion is provided, and the operating lever is positioned at an appropriate position corresponding to the gear position,
A device that can always operate normally L< times has been proposed.

When the positioning mechanism is incorporated into the transmission operating device in this way, the operation of the lever 011 is simply a matter of switching the retaining body to one of the retaining parts, and the desired changeover is made to the transmission. This has the advantage that the sprocket can be changed accurately and the opening time of the operating lever can be shortened, and there is no need to worry about shifting operations, allowing the user to concentrate on driving and steering.

However, when a positioning mechanism is incorporated, there is no problem if the configuration of both sets of the multi-stage tin rocket device and the spacing between the sprockets are the same, but for a sprocket device with different spacing between the sprockets, there is no problem. , for a sprocket device that cannot be used originally and has a different set configuration, the length of the operating wire that connects the speed change operating device and the transmission may be adjusted, and the position set by the positioning mechanism and the speed change device may be adjusted. It is necessary to align the position with the gear position in , and even if the operating wire is extended, the same alignment is required as described above.

By the way, the above positioning is especially important for racing bicycles used in road races, where the wheels need to be replaced during the race, and when the multi-stage sprocket devices installed on these wheels are changed, the spacing between the sprockets must be adjusted. Even if they are the same, as mentioned above, the position of the transmission will not match with each sprocket of the multi-stage sprocket device,
Since it takes a long time to align these positions, there is a problem that it cannot be applied to racing bicycles.

(Effects of the Invention) As described above, the present invention provides a friction mechanism and a positioning mechanism for the operation lever, and also enables the positioning operation and positioning inactivation when the lever is operated by the positioning member and the engaging body of the positioning mechanism. The positioning mechanism can be used preferentially, and this positioning mechanism makes it possible to easily and quickly change gears by operating the operating lever, while also allowing the operating wire to extend or the multi-stage sprocket to be adjusted. If the positioning mechanism cannot function without adjusting the length of the wire due to a change in the configuration of both sets of the device, a friction mechanism can be used to perform the speed change operation, which is particularly useful for bicycles used for road races. When applied, the loss time of adjusting the length of the wire can be eliminated.
