Front fork for cycle

摘要

A front fork including an outer cylinder 2 and a slidable inner cylinder 3 with working oil between them has a dust seal 5 and an oil seal 6 in sliding contact with the outer circumference of the inner cylinder. Between these seals there is a guide 7 which is also in sliding contact with the outer circumference of the inner cylinder and which is made of sponge or felt and is impregnated with grease or oil. The provision of this guide increases the lives of the other seals.
