Document Type and Number:
WIPO Patent Application WO/2019/244286
Kind Code:
A1
Abstract:
[Problem] To provide a valve mechanism, etc. that make it easy to achieve desired damping force. [Solution] A valve mechanism that comprises: an orifice collar 80 that has a through hole 82 that passes in the axial direction; a plurality of valve bodies 70 that include a spoke valve 71C that is arranged so as to contact an axial-direction end surface of the orifice collar 80; and a drive valve 61 that can move in the axial direction and is arranged on the opposite side of the plurality of valve bodies 70 from the orifice collar 80. The drive valve 61 comprises a shaft part 61j and a first step part 61b that extends toward the radial direction outside from the shaft part 61j. The shaft part 61j has a protruding part 61c that protrudes toward the orifice collar 80. Gaps between the plurality of valve bodies 70 can change as a result of inner peripheral parts of the valve bodies 70 that are contacted by the drive valve 61 when the drive valve 61 has moved toward the valve bodies 70 being elastically deformed in the direction of the orifice collar 80 relative to outer peripheral parts of the valve bodies 70.
