In a terminal such as M), a pulley (usually made of a synthetic resin) fitted to a shaft is used as a component of a device for accurately feeding bills one by one. Usually, three or more such resin pulleys are fitted and fixed to the shaft. Conventionally, as shown in FIG. 8, a small hole 11a is formed in the shaft 11 and the resin pulley 12 is also formed. A hole 12b is formed in addition to the hole 12a in which the shaft 11 is fitted, the positions of the hole 11a and the hole 12b are aligned, and the spring pin 13 is fitted and fixed from above, or as shown in FIG. A method of press-fitting and fixing a shaft 15 into a hole 14a formed in a resin pulley 14 has been used.

あった。When a resin pulley with a shaft is manufactured by the above-mentioned method, as shown in FIG. The position of the pulley 12 was unstable due to movement. Further, in the method shown in FIG. 9, there is a problem that the alignment between the hole of the shaft 13 and the hole of the resin pulley 14 is troublesome and difficult, so that the workability is poor. In some cases, a resin pulley with a shaft is manufactured by directly injection molding synthetic resin. However, when three or more resin pulleys are connected to a shaft and molded, a so-called cooling accompanying injection molding is performed. There was also a problem that accuracy was not obtained due to the problem of "closing".

するための工夫である。Next, in the resin pulley 2, the width D1 of the one groove 23 provided with the dead end 23a is substantially equal to the diameter d of a pin 3 (see FIG. 3) which will be described later, and the pin 3 passes therethrough. to allow degree of width, the width D 2 of the other groove 24 provided with a protrusion 25 and 25, the larger (wider) than the width D 1 of the groove 23 is formed. Thus, the protrusions 25, 25
The width D 2 of the other groove 24 provided with the groove 23 is made larger than the width D 1 of the groove 23 provided with the dead end 23 a because the accuracy of the angular position of these grooves 23 and 24 in the circumferential direction is slightly higher. Even if it is bad, it is a device for ensuring that the pin 3 enters each groove.

Next, a method of fitting and fixing the resin pulley 2 to the shaft 1 will be described. FIG. 3A is a longitudinal sectional view when the resin pulley 2 is fitted into the shaft 1, and FIG.
It is an AA arrow line view of (A). The shaft 1 has a hole 1
a is drilled, and a pin 3 is fitted in the hole 1a. With the pin 3 fitted into the shaft 1 in this manner, the shaft 1 is fitted into the hole 2a from the end on the side where the dead end 23a of the resin pulley 2 is formed. The pins 3 are provided with protrusions 25 provided on both sides of a groove 24 of the resin pulley 2,
Contact 25. In this case, the diameter d of the pin 3 is raised 25,
When the resin pulley 2 is still pressed, the protrusions 25, 25 are pressed by the pins 3 and elastically deformed.
Get over the bumps 25,25. As shown in FIGS. 4A and 4B, when the pin 3 gets over these protrusions 25, it comes into contact with a dead end 23a provided in one groove 23 of the resin pulley 2, and Therefore, the resin pulley 2 is fitted and fixed to the shaft 1 and cannot move in the axial direction. In this case, one of the protrusions 25 is provided with an inclined portion 25a so that the pin 3 can easily pass when the pin 3 passes.
Since the opposite side 25b is cut off at a substantially right angle, once the dead end 23a of one groove 23 and the other groove 2
The pin 3 fitted between the projections 25 of the 4 cannot be easily removed.
