Abstract: A damping device comprises an axle, a housing, a unidirectional member, and a damping oil. The unidirectional member in cross section is formed like a T-shape, and a top portion thereof is formed as an arc to cooperate with the housing's inner wall. Where the unidirectional member contains a U-shaped slot defines oil holes interlaced with the gap of the first slot wall.
