PURPOSE:To constitute an inertia damper in such a way that it may be stabilized without any bobble generated in gel material by forming a receival part in a shaft mounting with an inertia body mounted in the storage state, and joining the inertia part with the shaft mounting part with each other in this receival part as the vibration may be suppressed. CONSTITUTION:The inertia damper of a stepping motor 2 has a shaft mounting part 10 and an inertia body 20 joined with each other via gel material 30 as the vibration may be suppressed. The shaft mounting part 10 has a receival part 13 in which the inertia body 20 is mounted in a storage state and is joined with the body 20 in the receival part 13 as the vibration may be suppressed. When a gel material 30 is given between the inertia body 20 and the shaft mounting part 10, the unhardened gel raw liquid may be poured naturally and easily so that the inertia damper may be produced without any bobble and the like generated in the gel material after the liquid is hardened. The stable characteristics of the gel material may thus be applied effectively. |
