ことになるのである。(Prior Art) Conventionally, a transmission is provided with a speed change operating device and a transmission, and the movement caused by the rotation of an operating lever in the speed change operating device is transmitted to the transmission via an operating cable, and a chain guide of the transmission is used to control a multi-stage sprocket device. In a bicycle in which the chain is replaced with one sprocket, the speed change operation device includes, for example, a plurality of concave engaging portions, a locking body such as a ball that engages with one of the engaging portions, and the locking body. A positioning mechanism consisting of a spring that presses a body against the engaging portion is provided, and a gear position is determined by engagement of the locking body with the engaging portion, and at the same time, the lever is moved to a position corresponding to the gear position. If the operating cable is not extended, the chain guide of the transmission is placed in a stable area with respect to each sprocket of the multi-stage sprocket device, specifically, the chain does not come into contact with the chain guide or sprocket. Although it is possible to stop the chain guide in a stable area, if the operating cable stretches due to repeated gear shifting operations, the amount of operation of the operating lever remains constant, while the amount of movement of the chain guide is equivalent to the amount of elongation of the operating cable. As a result, the chain guide is misaligned with respect to the sprocket, and the chain guide stops outside the stable area. Therefore, the chain replaced by the chain guide becomes inclined with respect to the sprocket that meshes with the chain, and this chain comes into contact with the tips of the teeth of the chain guide or sprocket, causing noise.

ある。 By the way, in the case of a shift operating device equipped with a positioning mechanism, the operating lever is held at a position corresponding to the gear position, so even if the operating cable is extended, the operating lever cannot be rotated any further. be.

いる。 Therefore, conventionally, when the operating cable stretched between the gear shift operation device equipped with a positioning mechanism and the transmission is stretched, an adjustment bolt provided on the transmission is used to
The adjustment bolt is rotated to change the position of the end of the operating cable to adjust its effective length, thereby returning the chain guide to the stable area.

題があつた。(Problem to be Solved by the Invention) However, when adjusting the operating cable by rotating the adjuster bolt, the operation is performed at the boundary between the stable area and the unstable area outside the stable area. Since the length of the cable is adjusted, it is difficult to know how much to rotate the adjuster bolt in relation to the amount of extension of the operating cable, and it is difficult to adjust accordingly. Since a small amount of extension of the operating rope causes a transition from a stable region to an unstable region, there is a problem in that the frequency of adjustment is increased.

である。 In the present invention, when a chain is meshed with one sprocket of a multi-stage sprocket device, the chain does not come into contact with the chain guide or sprocket between the sprocket meshing with this chain and the sprocket adjacent to the sprocket. By focusing on the fact that there is a stable region with a predetermined width and making it possible to adjust the length of the operating rope in stages using this stable region width as a guide, the operating rope can be adjusted easily and quickly. This makes it possible to reduce the frequency of operations.

This is the area where no noise occurs when the chain contacts the teeth of a matching sprocket, or when the edge of a pin of a chain comes into contact with the teeth of a sprocket adjacent to the sprocket that meshes with the chain. The stable region width H is determined by the type of sprocket, chain guide and chain, the distance between each sprocket, the shape of the sprocket teeth, the difference in the number of teeth between each sprocket, etc.

る。 The adjusting device configured as described above is attached to the operating lever 71 of the speed change operating device 7 having a positioning mechanism 72 for setting the position of the operating lever 71 as shown in FIGS. 7 and 8, for example. A screw hole 7 is provided in the wire hooking part of the operating lever 71.
3, and the first screw 21 of the holder 2 is screwed into the screw hole 73, while a hook 1 is provided at one end.
2 is fixed to the operating wire 11, which is attached to the support tube 3b.
The wire 11 is inserted into the insertion hole of the holder 2, and the hook body 12 is hooked to the hook portion 2, and the tip of the wire 11 is fixed to a movable side member of a transmission having a chain guide G. , the operating lever 71
transmitting the operating force to the movable side member via the wire 11 to move the chain guide G in the axial direction of the constant stroke multi-stage sprocket device,
When the chain is replaced with one sprocket of the multi-stage sprocket device, initially, as shown in FIG. 2, the engaging protrusion 41 is engaged with the setting surface 34 of the lower stage than the control surface of the lower stage. In this state, the chain guide G is in a stable region with respect to the sprocket with which the chain engages, as shown in FIG.

に戻るのである。 As a result, the wire 11 stretches due to repeated speed change operations using the operating lever 71, and the chain guide G stops in an unstable region O outside of the stable region, causing a noise when the chain is engaged with the sprocket S. If this starts to occur,
Rotating the receiver 4 using the adjustment lever 42 causes the engagement protrusion 41 of the receiver 4 to engage one of the three control surfaces 31, and as the receiver 4 rotates, The engaging position of the engaging protrusion 41 is displaced, and the actuating body 3 moves the operating wire 1 against the force of the spring 6.
At the same time, the wire 11 supported by the operating body 3 is pulled in the direction of the arrow in FIG. 8, and the tension of the wire 11 causes the chain guide G to move in the direction of the arrow in FIG. and returns to a stable region.

るのである。 In this case, since the control surface 31 is displaced stepwise in the length direction of the operating wire 11, it is sufficient to perform an operation of rotating the receiver 4 by a certain angle. teeth,
Since the number of sprockets S is equal to the distance L between the sprockets S divided by the length corresponding to the stability area width H, the engagement protrusion 41 can be engaged with one of the control surfaces 31 by rotation of the receiver 4. This allows the chain guide G to be accurately returned to the stable region.
Furthermore, since the chain guide is moved all at once by a length corresponding to the stable area width H, even if the wire 11 stretches a little, there is more margin for the chain guide to come out of the stable area, and the frequency of adjustment can be increased accordingly. It can be done less. Furthermore, since the gear can be adjusted by changing the gear position while riding and driving the bicycle, the adjustment can be made very easily.

is not necessarily necessary. In this case, for example, a non-circular rotation operation part may be provided on the outer periphery of the receiver 4, or
Alternatively, a rotary operating section having a large number of concave and convex stripes is provided, and these are collectively referred to as the manual operating section.

のである。(Effect of the invention) As described above, the present invention has a very simple operation in which the engaging protrusion is switched to engage one of the control surfaces by one operation of the actuating body and the receiving body. The adjustment operation can be made simply and quickly.Moreover, since the length set using the stable area width as a guide is adjusted all at once, the length of the operating cable will not be slightly out of order. There is no need to adjust it each time, and the frequency of adjustment can be reduced accordingly.
