れる。Here, when the rotor shaft 3a of the pulse motor 3 rotates, the rotor shaft 3a tends to run at an inherent resonance frequency. However, since the rotationally symmetric wheel 8 is attached to the end of the rotor shaft 3a, the rotor shaft 3a
The rotor shaft 3a rotates stably due to the moment of inertia of the wheel 8 caused by the rotation of the rotor 8, and the shaft runout of the rotor shaft 3a is suppressed. Accordingly, noise generated from the meshing portion between the gear 7a and the gear 7b and the meshing portion between the gear 7c and the gear 7d due to the shaft runout of the rotor shaft 3a are reduced.

However, the present invention is not limited to this, the shape is rotationally symmetric, and the axis of symmetry is the rotor axis 3a.
If it is fixed coaxially, various other shapes can be applied as the shape of the wheel 8.
