1. A damper device comprising:
a piston body; a cylinder body having a partition partitioning the cylinder body to a first chamber, and a second chamber accommodating the piston body; a flow channel formed in the partition, and communicating the first chamber and the second chamber with each other; a cap body disposed in the first chamber to divide the first chamber from an outside, and including a main body portion with a through-hole, and an elastic portion formed integrally on a central portion of the main body portion and spaced to increase a distance from the main body portion toward a radial direction of the cylinder body; and a throttle structure including the through-hole formed in the main body portion, a tapered shaft projecting from the partition into the first chamber through the through-hole so that the main body portion is movable disclosed over the through-hole from a reference position along an axis line of the cylinder body, and a gap arranged between the through-hole and the shaft and being changed when the cap body moves from the reference position by a pressure change generated by a movement or a relative movement of the piston body, wherein at least one of the cylinder body or the piston body is adapted to attach to a damping object to damp a movement or a relative movement of the damping object. |
