Provided are a steering device capable of absorbing a large impact force, a damper that can be applied to the steering device, and a flow control valve that can be applied to the damper. A steering device (100) is provided with a damper (120) between a rack bar (103) and a rack-and-ball joint mechanism (106). The damper (120) has an inner cavity (121) formed in the outer peripheral portion of the socket body (107), and the integrated displacement body (130) is slidably fitted to the damper (120). In the integrated displacement body (130), a flow control valve (140) is formed in an annular shape in the inner peripheral portion. The flow control valve (140) is provided with a first flow control valve (150). The first flow control valve (150) is provided with a second flow body (156) that is close to or away from the first flow body (153). The second circulation body (156) is formed in such a manner that a second circulation hole (157) is formed at a position shifted from a first circulation hole (154) formed in the first circulation body (153), and the first circulation hole (154) is closed by a second aperture restricting section (158).

    提供能够吸收大的冲击力的转向装置、能够应用于该转向装置的阻尼器、以及能够应用于该阻尼器的流通控制阀。转向装置(100)在齿条杆(103)与齿条球关节机构(106)之间具备阻尼器(120)。阻尼器(120)在承窝主体(107)的外周部形成有内腔(121)并且供一体位移体(130)以能够滑动的方式嵌合。在一体位移体(130)中,在内周部呈圆环状形成有流通控制阀(140)。在流通控制阀(140)设置有第一流通控制阀(150)。第一流通控制阀(150)具备相对于第一流通体(153)接近或远离的第二流通体(156)。第二流通体(156)形成为在相对于形成于第一流通体(153)的第一流通孔(154)错开的位置形成有第二流通孔(157)并且第二孔径限制部(158)堵住第一流通孔(154)。
