Abstract: Provided is a front fork spring leg capable of stably maintaining air spring characteristics. The front fork spring leg has an inward-facing seal member, an outward-facing seal member, and a piston ring arranged on an outer periphery of a guide of a guide rod sequentially in this order along an axial direction of the guide from the side close to an inner air spring chamber toward the side far from the same. The inward-facing seal member has a lip which is slidably in contact with the inner periphery of the guide cylinder, with this lip being oriented toward the inner air spring chamber while the outward-facing seal member has a lip which is slidably in contact with the inner periphery of the guide cylinder, with this lip being oriented in the opposite direction to the inner air spring chamber.

Abstract: A shock absorber includes an outer tube, an inner tube fitted to the outer tube so as to be able to move forward and backward, a cylinder provided inside the outer tube and extending inside the inner tube, a rod extending from an end portion of the inner tube exposed from the outer tube to an inside of the cylinder, and a piston which is provided on the rod and divides the inside of the cylinder to form a gas chamber. On an outer peripheral surface of the piston, a first lubricating member, a first seal member, and a second seal member are provided in this order from a side closest to the gas chamber to a side away from the gas chamber. The members are in sliding contact with an inner peripheral surface of the cylinder.

Abstract: A front fork includes a first shock absorber and a second shock absorber disposed respectively on both sides of a vehicle wheel. The first shock absorber includes a set of tubes configured to slide relative to each other; damping force generation parts configured to generate a damping force in accordance with the sliding of the tubes; and a spring configured to urge the set of tubes in a stretching direction. The second shock absorber includes a set of tubes configured to slide relative to each other; and a coil spring configured to urge the set of tubes in the stretching direction.
