Abstract: A suspension device includes a leaf spring and a buffer. The leaf spring applies an elastic force for relatively moving an unsprung member in a predetermined direction with respect to a body (sprung member) of a vehicle. The buffer includes a first expansion/contraction member, a second expansion/contraction member, an intermediate member, and a damping passage. The first and second expansion/contraction members form first and second gas chambers filled with gas therein and are expandable and contractible. An upper end and a lower end of the first and second expansion/contraction members are connected to the body. The intermediate member couples the first and second expansion/contraction members and is connected to the leaf spring. The damping passage allows the first and second gas chambers to communicate with each other, and applies resistance to flow of flowing gas. When one of the first and second expansion/contraction members expands, the other contracts.
