Abstract:
1. A front fork comprising: a fork body having an outer tube and an inner tube relatively movably inserted into the outer tube in an axial direction; a damper housed in the fork body to dampen relative movement between the outer and inner tubes; a biasing member that biases the fork body in an expansion direction at all times; an annular dust seal that is held in the outer tube and makes sliding contact with an outer circumference of the inner tube to prevent intrusion of a foreign object into the fork body; an annular oil seal that is held in the outer tube inside the fork body to be inner than the dust seal and makes sliding contact with the outer circumference of the inner tube to prevent leakage of an actuating liquid contained in the fork body; and a C-shaped scraper that is provided between the dust seal and the oil seal and makes sliding contact with the outer circumference of the inner tube; wherein the scraper is in direct contact with both the dust seal and the oil seal so as to receive forces therefrom to suppress diameter expansion.
