部品点数が多いため、組立工数を多く必要とする
という欠点がある。 FIG. 1 shows a conventional fixing structure. Set cam 2 to 2nd
When tilted as shown in the figure, the arm 4 is pulled up. Arm 4 is fixed to lock 1 by retainer 5, so that as arm 4 is pulled up, lock 1, which is attached to object 8 by screw 7, deforms. As a result, the shaft 6 passing through the object 8 is tightened, and the object 8 is fixed to the shaft 6. However, in such a conventional structure,
Since there are a large number of parts, there is a drawback that a large number of assembly steps are required.
本考案の目的は上述の欠点を除去し部品点数の
少ない組立工数の少ない固定構造を提供すること
にある。 An object of the present invention is to eliminate the above-mentioned drawbacks and to provide a fixing structure with a small number of parts and a reduced number of assembly steps.
次に図面を参照して本考案を詳細に説明する。 Next, the present invention will be explained in detail with reference to the drawings.

いる。 In the figure, the fixing structure of the present invention includes a cantilever part 9 having a sliding part, a circumferential part 10 connected to the cantilever part 9 and integrally formed with the cantilever part, and a circumferential part 10 connected to the cantilever part 9. Attachment part 11 integrally molded with the circumferential part
It has a lock 40 consisting of. A cam 12 rotatably attached to the object 17 via a pin 14 has the function of contacting the cantilevered portion and pushing down the cantilevered portion 9 by rotational movement.

１５に固定される。 The operation of the fixing structure shown in FIG. 3 will be explained using FIG. 4. When the cam 12 is rotated about the shaft 14, the cantilevered portion 9 is pushed down, and in response, the circumferential portion 10 tightens the shaft 15. Since the lock 40 is fixed to the object 17 by the screw 16 of the attachment part 11, the object 17 is fixed to the shaft 15 by rotation of the cam 12.

ラクタ本体１８に相当する。 FIG. 5 shows an example in which the fixing structure of the present invention is applied to a tractor used for feeding paper in a printer. The feed belt 19 is driven by a drive shaft 21 via a pulley 20, and the printing paper of the printer is engaged with a pin 22 formed integrally with the feed belt 19 and is fed. By the way, since the size of printing paper varies, the tractor must be able to move in the direction of arrow 23 depending on the size of the printing paper and must be fixed at a predetermined position. For this purpose, the fixing structure according to the present invention shown in FIG. 3 can be used as is. The object 17 in FIG. 3 corresponds to the tractor body 18 in FIG.
