Abstract
A front fork leg includes an inner chamber that absorbs by a gas spring a shock caused on a vehicle; an auxiliary gas spring chamber communicating with the inner chamber; an auxiliary piston provided in the auxiliary gas spring chamber; and a gas spring chamber side gas chamber sectioned by the auxiliary piston and communicating with the inner chamber, and the auxiliary piston moves to increase a volume of the gas spring chamber side gas chamber, as pressure inside the inner chamber increases.
Claims17
A shock absorber, comprising:
- a shock absorber main body that absorbs a shock input to a vehicle;
- a gas spring chamber which is provided inside the shock absorber main body, and inside which gas is sealed, and which absorbs the shock by a gas spring that is based on the gas;
- an auxiliary gas spring chamber, inside which the gas is sealed, and which communicates with the gas spring chamber, and which is formed in a cylindrical shape;
- a movable partition wall which is provided slidably in an axial direction inside the auxiliary gas spring chamber;
- a gas spring chamber side gas chamber which is sectioned by the movable partition wall in the auxiliary gas spring chamber and which communicates with the gas spring chamber;
- and
- an elastic body side gas chamber which is sectioned by the movable partition wall in the auxiliary gas spring chamber, and which is formed on an opposite side of the movable partition wall to the gas spring chamber side gas chamber, and which has an elastic body having a prescribed modulus of elasticity that urges the movable partition wall towards the gas spring chamber side gas chamber, wherein
- the movable partition wall moves towards the elastic body side gas chamber so as to increase a volume of the gas spring chamber side gas chamber, as pressure inside the gas spring chamber increases.
