て操作するごとくした自転車用変速操作装置に関する。[Detailed Description of the Invention] The present invention relates to a bicycle speed change operation device, and more specifically, a lever is supported to freely swing on a fixed member fixed to a bicycle frame, and a derailleur operating member is connected between the lever and the derailleur. The present invention relates to a bicycle gear shift operating device which is operated via an operating wire stretched between an operating member of the bicycle.

ーを相反する二方向に揺動操作しなければならなかった
のである。Generally, this type of operating device has a return spring that moves the operating member forward by operating a lever in the indexing direction of the operating wire, and switches the operating member to the derailleur by operating the lever in the direction of loosening the wire. Because the gear was configured to move backwards with the force of , the lever had to be swung in two opposite directions when changing gears.
従って、変速操作が煩わしいばかりか、操作方向を間違
える恐れが高かったのである。Therefore, not only is the gear shifting operation cumbersome, but there is also a high risk of making a mistake in the operating direction.
そこで従来、固定部材に１対の第１及び第２レバーを揺

り変速することができるようにした操作装置が提案され
た。Conventionally, a pair of first and second levers is supported by a fixed member so as to be able to swing freely, an operating wire is connected to the first lever, and a positioning plate is provided between the levers, and the respective levers and the positioning plate are connected to each other. In between, at the operating position of each lever,
A locking mechanism is provided for positioning and holding one lever and releasing the second lever, so that when the first lever is swung in the direction in which the wire is pulled, the second lever is moved.
When the lever is swung in the direction of loosening the wire by the return spring, and the second lever is swung in the direction of pulling the wire, the force of the return spring in the derailleur causes the second lever to be swung in the direction of loosening the wire. An operating device has been proposed in which the gear can be changed by swinging the lever to one side.

ーを前記ワイヤーの緩み方向に揺動させることができず
、従って、確実に変速することができない事態を招来す
る問題があった。However, in this conventional operating device, since the force of the return spring in the derailleur is used to swing the first lever to which the operating wire is connected in the direction in which the wire is loosened, it is difficult to guide the operating wire. If the outer tube is bent at a right angle by a wire guide or the like, or if the outer tube is caught on bicycle equipment or the like and bent, the frictional resistance between the operating wire and the outer tube increases. The derailleur
If the force of the return spring toward the wire no longer acts sufficiently on the first lever through the wire, the first lever cannot be swung in the direction in which the wire is loosened, and therefore the gear cannot be reliably shifted. There was a problem that led to the situation.
本考案は以上の如き従来の問題点に鑑み考案したもので

けたことを特徴とするものである。The present invention was devised in view of the above-mentioned conventional problems.The frictional resistance between the operating wire and the outer cylinder increases, and the force of the rear and tonne springs in the derailleur is transferred to one side via the operating wire. Even if the lever does not work sufficiently, it is possible to reliably shift gears by swinging the other lever. It is characterized by providing an interlocking mechanism that reversibly transmits the transmission and forcibly swings the other lever in the opposite direction to the swinging direction of one operating lever.
。。以下本考案の実施例を図面に基づいて説明する。. . Embodiments of the present invention will be described below based on the drawings.

できるのである。As described above, the present invention reversibly transmits the swinging motion of one lever to the other lever between a pair of levers, and causes the other lever to move in the opposite direction to the swinging direction of one operating lever. Since we have provided an interlocking mechanism that forces the lever to swing, the frictional resistance between the operating wire and the outer cylinder increases, and the force of the return spring in the derailleur acts on one lever via the operating wire. Even if it runs out, you can reliably shift gears by swinging the other lever.
