No. 358, "■ Manufacturing method for ribbed boobies," states that the bottom wall part is made thinner than the metal material by pressing the metal material, and the peripheral wall part is made plastic by keeping the thickness of the metal material unchanged. Is there a description of forming the inner and outer circumferential surfaces of the surrounding area correctly parallel to the axial direction, and at the same time forming the 7 rung part, and then forming a precise poly V groove with a b60-ra? As a result of the proof printing, we found that when used to drive a vehicle engine, the humidity of the poly V held increases significantly due to the increased humidity in the engine room and the drive of the poly V held. The problem was that it would age and break and break.

うものである。In order to eliminate the above-mentioned drawbacks, the present invention increases the surface area of the poly V-boo to dissipate heat, and also generates air turbulence near the inner peripheral surface of the poly-V boo. The purpose is to actively dissipate the heat generated by the poly V pulley from its surface, reduce the frictional heat generated by the rotational torque of the poly V pulley with the poly V heald, and prevent aging of the poly V pulley. Specifically, in order to increase the surface area on the entire inner circumferential surface of the peripheral wall of the Bo+ and +V boobies, a large number of uneven grooves are provided, and the uneven grooves on the entire inner circumferential surface dissipate heat. It increases the surface area of the V-boo and uses uneven grooves to generate air flow around the IJ V-boo and actively dissipate heat.

As shown in FIG. 6(A), trapezoidal grooves 40 are formed parallel to the axis over the entire inner peripheral surface, and as shown in FIGS. 6(C) and (D), Instead of the trapezoidal shape of the uneven groove, a wave-like one or a semicircular one may be used. Furthermore, as shown in FIG. It is also possible to provide a threaded shape such that the inner peripheral surface roller can be removed by providing θ. However, in this case, it is appropriate for θ to be approximately 15 degrees or less from the insertion and removal of the inner roller, and since the uneven grooves are provided diagonally, it is possible to send air toward the bottom wall, which improves heat dissipation. The effect will be even better.

The surface area of the inner circumferential surface of the boob is increased to improve heat dissipation, and furthermore, air is randomly added to the inner circumference of the boob 11 to improve heat dissipation. This is to prevent the poly V belt from deteriorating due to heat as much as possible. Incidentally, the uneven grooves on the inner circumferential surface can also be formed at the same time as rolling the poly V boo groove.
