Claims

[Claims for Utility Model Registration] (1) In a vibration reduction device for a steering device in which a dynamic damper consisting of a mass body and an elastic body is attached to a steering pipe to reduce vibration, the mass body is provided with a recess or a convexity. A vibration reduction device for a steering device, characterized in that a fixed portion facing the mass body is provided with a convex portion or a concave portion that loosely fits into the concave portion or convex portion. (2) The vibration reduction device according to claim 1, wherein a stopper piece made of an elastic material is attached to at least one surface of the concave portion and the convex portion that fit loosely into each other. (3) The recessed portion and the convex portion that fit loosely into each other are tightly fitted together when the rotational speed of the engine is outside a predetermined range, thereby preventing vibrational movement of the mass body. Vibration reduction device as described in section.
