バネＩ７ｉ力で移動するように構成するとよい。In this case, the movement of the tension pulley in the belt tensioning direction is very heavy. To make this lighter, it is recommended to attach a Herance spring to the tension pulley so that it moves in the belt tensioning direction with the force of the spring I7i.

ない。It is good to use several adjustment levers for the purpose of preventing the tension pulley from moving freely.However, in order to attach the balance spring to the tension pulley and configure it as described above, the lever must be installed directly on the tension pulley. This is possible only when the tension pulley and lever are connected using a wire, and the balance spring cannot be attached to the tension pulley.

ネを取付けることができるようにしたものである。Therefore, the present invention has been devised in this respect, and a V-belt 5 is hooked and rotated between the driven pulley 1 and the drive-side belt pulley 2, which has a fixed side pulley 3 and a moving side pulley 4. A speed change lever 22 is provided which operates a tension boob 0-6 to move the tension pulley 6 to a desired position, and the tension pulley 6 and the speed change lever 22 are connected by a wire 17, and the speed change lever 22 has a , the continuously variable transmission is equipped with a balance spring 26 that can move the speed change lever 22 in the belt tensioning direction, and even if the tension pulley and the lever are connected by a wire, the balance spring can be attached to the tension pulley. This is how it was done.

片１９を形成し、屈曲片１９に切欠部２０を形成する。To explain with reference to the drawings, 1 is a passive pulley, 2 is a drive-side bell-con pulley, and 3 is a drive-side bell-con pulley 2.
The fixed side pulley 4 is the moving side pulley of the driving side Belcon pulley 2, and the fixed side pulley 3 and the moving side pulley 4 are
The distance between the two can be adjusted freely by the spring 21. 5 is a V connected between the passive pulley 1 and the driving side belt pulley 2.
A tension pulley 6 acts on the middle of the V-belt 5. The tension pulley 6 is pivotally attached to the tip of a swinging arm 7 via a shaft 8, and the swinging arm 7 is pivoted to the frame via a shaft 9. A wire 17 is attached to the middle part of the swing arm 7, and the other end of the wire 17 is attached to the speed change arm 16. The speed change arm 16 is pivotally attached to a shaft 25, and the sliding shaft 12 is connected to the lower end of the lower protrusion 18 by the shaft 14.
Attach the head to the shaft. The leg portion 13 of the sliding shaft 12 is inserted through a bearing 10 fixed to the frame, and a stopper 11 is installed. A balance spring 26 is wound between the bearing lO and the shaft 14, and is biased to keep the bearing 10 and the shaft 14 apart. The soil portion of the speed change arm 16 is bent laterally to form a bent piece 19, and a notch 20 is formed in the bent piece 19.

溝２３内に係合させる。The lower end of the speed change lever 22 is engaged with the shaft 25 via the spring 15, and the speed change lever 22 is moved through the notch 20 by the elasticity of the spring 15.
so that it engages with The upper end of the speed change lever 22 is engaged in the guide groove 23.
次に作用を述べる。Next, we will discuss the effect.

。When the lever 22 is rotated in the direction of arrow A against the spring 15, for example, when it is disengaged from the engagement groove 24 at "3" and engaged at "1", the elasticity of the balance spring 26 lightly moves the shift arm 16. Since the gear is rotated clockwise, the tension pulley 6 rises due to the elasticity of the balance spring 26 and tensions the V-belt 5. Therefore, the gear shift lever 22 moves very lightly and engages rlJ. If you work in this state, the gear shift lever 22 will
1", the tension pulley 6 rises to the maximum, and the V-belt 5 bites into the driving side belt pulley 2 to the maximum, so the driven pulley 1 rotates at the lowest speed. Even if a load is applied to the wire 17 depending on the working condition, the belt 5 will not bite into the driving side belt pulley 2 because the speed change lever 2i is engaged with the engagement groove 24.

付けることができなかった。As already mentioned, the V-pulley and the bell-con pulley are provided facing each other, and the belt is hung and rotated, and the tension pulley is applied to the belt, and the tension pulley is moved to adjust the effective diameter of the bell-combo-2 In the case of the one that changes the belt, the movement of the tension boot 〇- is very heavy when it is in the belt tensioning direction. In order to make this lighter, it is better to attach a balance spring to the tension pulley so that the belt moves in the direction of tension due to the elasticity of the spring. However, it is better to attach a balance spring to the tension pulley and configure it as described above. This is possible only when the lever is attached directly to the tension pulley.
When connecting the tension pulley and the lever with a wire, it was not possible to attach the balance spring to the tension pulley.
