Reference numeral 20 denotes an electric drive body, and a drive pulley 22 is fixed to an end of a rotary shaft 21 of the electric drive body 20. At the same time, a torque wrench mounting portion 23 composed of a hexagonal seat for mounting a torque wrench (not shown) is formed at the tip of the rotary shaft 21.

プラグを示す。Reference numeral 24 denotes a driven body, and a driven pulley 26 is fixed to an end portion of a transmission shaft 25 of the driven body 24, and a belt 27 is wound between the driven pulley 26 and the drive pulley 22. Together with the transmission shaft 25, a torque wrench mounting portion 2 formed of a hexagonal seat for mounting a torque wrench (not shown) at the tip end portion is formed.
Formed 3. The electric drive body 20 is attached to a belt 28 fixed to the driven body 24 so that the base 28 fixed to the driven body 24 can be moved up and down through a nut 30 so as to move up and down. It is attached so that it can be moved in the direction in which it is stretched. In the figure, 31 is the drive shaft of the work,
32 is a rotary encoder, 33 is an oil level gauge, and 34 is an oil supply plug.

値となったときナット３０を固定する。Thus, when the electric drive body 20 is started, the driven pulley 26 is rotated via the belt 27 and the transmission shaft 25 is rotated with a required rotational torque. When the tension of the belt 27 is adjusted, the transmission shaft 25 is first moved. It is detected by fixing the torque wrench mounting portion 23 formed on the tip end portion with a wrench or the like, mounting the torque wrench on the torque wrench mounting portion 23 formed on the tip end portion of the rotary shaft 21, and rotating the torque wrench. The friction torque of the belt 27 is determined based on the torque value of the electric drive unit 20.
Is moved up or down and measured again with a torque wrench, and when it reaches a predetermined value, the nut 30 is fixed.

した構成に限定されないことは言うまでもない。By using the torque wrench in this way, the friction torque of the belt can be easily measured, and if it is different from the set value, it can be easily corrected through the adjusting bolt. In addition, in the above, the torque wrench mounting portion is formed on both the tip ends of the rotary shaft and the transmission shaft,
One may be formed so as to be fixable with a spanner or the like, and both need not necessarily be formed so that a torque wrench can be mounted, and the shape is not limited to the hexagonal seat. Needless to say, the adjusting bolt is not limited to the above-mentioned structure.
