Abstract: There is provided a damper that can reduce a shock when a piston speed reaches a high speed range from a low speed range without deteriorating a ride comfort while the piston speed is in the low speed range. In order to solve the above-mentioned problem, in a damper D of the present invention, since a orifice (7) and an opening/closing valve (9) are arranged in parallel with a bypass passage (B) bypassing a damping passage (3), and a valve opening pressure of an opening/closing valve (9) is made lower than a valve opening pressure of a damping valve (5), a sudden change in an inclination of a damping force characteristic can be moderated at an inflection point of the damping force characteristic even if the damping force is increased while the piston speed is in the low speed range.

Abstract: There is provided a shock absorber enabling a shock at the time of transition from a low speed region to a high speed region to be reduced without impairing ride quality in an ultra-low speed region. The shock absorber includes a compression-side second damping passage connecting two chambers to each other by bypassing a compression-side main valve opening/closing a compression-side first damping passage connecting the two chambers to each other to give resistance to flow of liquid flowing in the compression-side first damping passage and a compression-side throttle valve throttling the compression-side second damping passage. The compression-side throttle valve includes a housing including a valve seat, a case inserted in the housing, a valve body movably inserted at one end thereof in the case, and a coil spring biasing the valve body to the side of the valve seat.
