To provide a belt transmission comprising a drive pulley whose external teeth are not deformed even if performance of an electric motor is measured while fitting a facility input shaft into a facility shaft hole of the drive pulley fixed to an output shaft of the electric motor.SOLUTION: A drive pulley 36 comprises: a first hole 36a which is formed over a predetermined first range Ar1 from an end at the side of a motor M in an axial direction of an output shaft 37 and to which the output shaft 37 is fitted so as to be integrally rotatable; and a second hole 36b which is formed over a predetermined second range Ar2 from an end at an opposite side of the side of the motor M. A plurality of convex shapes S are formed at equal intervals over a full circumference in a circumferential direction on an inner peripheral surface of the second hole 36b. First phases β1 which are phases of tops T of the convex shapes S in the circumferential direction of the second hole 36b and second phases β2 which are phases of bottoms of tooth grooves 36g in a circumferential direction on an outer peripheral surface are not matched at all or are matched only in one location.SELECTED DRAWING: Figure 5

    【課題】電動モータの出力軸に固定される駆動プーリの設備軸用孔に設備入力軸を嵌合させ電動モータの性能を計測しても外歯が変形しない駆動プーリを備えたベルト伝動装置を提供する。【解決手段】駆動プーリ36は、出力軸37の軸線方向においてモータM側の端部から所定の第一範囲Ar1に亘って形成され、出力軸37が一体回転可能となるよう嵌合される第一孔36aと、モータM側とは反対側の端部から所定の第二範囲Ar2に亘って形成される第二孔36bと、を備え、第二孔36bの内周面には、凸形状Sが周方向全周に亘って等間隔で複数形成され、第二孔36bの周方向における凸形状Sの頂部Tの位相である第一位相β1と、外周面において歯溝36gの底部の周方向における位相である第二位相β2と、は全く一致しないか又は1箇所のみ一致する。【選択図】図5
