<p>To provide a solenoid controlled damper with a variable damping force, the damper being configured so that effects including a reduction in electric power consumption are achieved by preventing a valve plate from opening excessively during high-speed operation. [Solution] The valve body (53) of an extension-side valve plate (41) is opened by being pressed by hydraulic oil flowed from an extension-side first communication oil path (36). This, together with the flow of the hydraulic oil flowing through a flow rate adjustment hole (52), causes the hydraulic pressure on the upper surface side (solenoid coil (43) side-surface) of the valve body (53) and the hydraulic pressure on the lower surface side thereof to be substantially equal to each other within an extension-side pressure accumulation chamber (71). As a result, even if a damper (6) moves at high speed to the extension side and the inflow speed of the hydraulic oil from the extension-side first communication oil path (36) increases, the valve body (53) of the extension-side valve plate (41) is not likely to open excessively.</p> |
