この発明は、車両用バックミラー、特に、自動二輪車用
バックミラーの防振装置に関する。DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a vibration isolating device for a rearview mirror for a vehicle, particularly for a rearview mirror for a motorcycle.
車両用、例えば、自動二輪車用バックミラーは運転者が
後方を確認するためのものであるため、振動しないこと
が望ましい。Rearview mirrors for vehicles, for example, motorcycles, are used by drivers to check what's behind them, so it is desirable that they do not vibrate.
このため、従来にあっては、かかる振動を防ぐ必要上、
バックミラーのハウジング内に弾性材を介して重りを自
由運動可能に支持し、所謂、ダイナミックダンパの原理
を利用したものが考えられていた（特開間第５７−３３
０４４号）。For this reason, in the past, in order to prevent such vibration,
A rearview mirror that utilizes the principle of a so-called dynamic damper, in which a weight is supported so as to be freely movable through an elastic material within the housing of the rearview mirror, has been considered (Unexamined Japanese Patent Publication No. 57-33).
No. 044).
