イルリーク量コントロール機構。 In a shock absorber in which a piston rod is slidably held by a rod guide, the rod guide is formed with an annular recess opening on an inner circumferential surface,
An oil seal is housed in this annular recess, and an orifice passage for generating damping force is formed between the oil seal and the inner surface of the annular recess. Furthermore, the oil seal is arranged between the outer periphery of the piston rod and the inner periphery of the oil seal in the low speed range. An oil leak amount control mechanism for a shock absorber is characterized in that it prevents oil leaks from the piston rod and allows oil leaks from between the outer periphery of the piston rod and the inner periphery of the oil seal in medium and high speed ranges.
