Further, a fixing means (5) such as plastic such as epoxy resin, polyamide resin, urethane resin, melamine resin, or solder may be interposed between the inner circumferential wall e21 and the outer circumferential wall.
Alternatively, fixing means may be provided by interposing a 7-hook between the inner circumferential wall (2) and the outer circumferential wall (Q1) and heating to fuse the inner circumferential wall (2) and the outer circumferential wall. The above fixing means (5
) is desirable to ensure smooth heat conduction between the inner circumferential wall (b) and the outer circumferential wall, and for this purpose methods such as soldering and fusion are selected, but plastic with good thermal conductivity such as metal or carbon Powders may be mixed.

[Operations and Effects] The present invention As mentioned above, the circumferential wall of the metal cylinder has a double structure, and a plurality of V grooves are formed on the outer surface of the circumferential wall. Therefore, if the outer side of the circumferential wall, that is, the outer circumferential wall, is formed with V grooves, even if the circumferential wall becomes thin, The inner peripheral wall of the pulley is reinforced, and deformation or damage to the peripheral wall of the pulley is prevented even if external forces such as tension of the belt or shearing force due to rotation are applied. Furthermore, by interposing the fixing means between the double structures, it is possible to prevent the generation of abnormal noise due to repeated separation and contact between the inner circumferential wall and the outer circumferential wall when the pulley rotates, and the fixing means and 1. If the heat conduction between the inner peripheral wall and the outer peripheral wall is made smooth, the thermal deformation of the inner peripheral wall and the outer peripheral wall will substantially match, thereby preventing the occurrence of thermal distortion.
