Claims

[Scope of utility model registration request]

In a variable speed drive device in which a transmission 23 is interposed between an electric motor 21 and a driven body 22 rotationally driven by the electric motor 21 and a driven body 22 that changes the rotation speed of the driven body 22 in stages, the input of the transmission 23 is Shaft 24 and output shaft 2
5 and 5 are arranged so that the input shaft 24 is arranged on the lower side and the output shaft 25 is arranged on the upper side and protrudes from the transmission case 26 in the same direction, so that the input shaft 24 is directly connected to the motor shaft 21a of the electric motor 21, and the output shaft A belt 29 is wound between the pulley 27 fixedly installed on the transmission 25 and the input pulley 28 of the driven body 22.
3. A speed change drive device characterized in that a transmission support means 32 is provided with a spring 30 or a turnbuckle 31 for tensioning and supporting the speed change case 26 of No. 3 from the opposite side of the electric motor 21.
