摘要： PROBLEM TO BE SOLVED: To improve assembly property and durability of a shock absorbing mechanism, since there is a problem wherein assembly properties and durability are impaired because a small elastic part is interposed between a driven gear and a driven shaft in such a way as to provide a shock absorbing action in a rotational direction, in a shock absorbing mechanism for absorbing gear engagement shocks generated by starting or stopping of an electric motor, for example, in the case of a speed reduction gear train for a disc grinder. SOLUTION: The shock absorbing mechanism is configured so as to absorb the shock in such a way that by means of relative rotation between the driven gear 12 and the driven shaft 13, this relative rotation being caused by rotational power during engagement, steel balls 21, 21 are made to undergo displacement in a diameter expansion direction, and that thereby an axial displacement member 22 is made to undergo axial displacement in resistance against an axial elastic member 23.
