PURPOSE:To provide an advantageous sealing mechanism, which gives little resistance especially under a high speed rotation condition, for a sealing mechanism formed for purposes of dust prevention and waterproof toward rotary shaft parts in varied kinds of mechanisms. CONSTITUTION:In a sealing constitution between a rotary shaft member 16 and a fixed member 18 serving as a bearing member for the rotary shaft member 16, a centrifugal force sealing mechanism 1, which is installed in the rotary shaft member 16 and uses centrifugal force due to the rotation of the rotary shaft member 16, is provided. |
