STEERING SYSTEM

The invention provides a steering system. The steering system (1) includes an upper jacket (3), a lower jacket (4), a support (2), a lock mechanism (5), and a shock absorber (6). The support (2) supports the lower jacket (4). The lock mechanism (5) switches a restriction of a telescopic adjustment and a termination of the restriction. The upper jacket (3) includes a protruding stopper (31) configured to regulate a position of the upper jacket (3) at one end of a telescopic stroke range. The lock mechanism (5) includes an opening and closing portion (70) configured to enter a path of the stopper (31) while the restriction of the telescopic adjustment is terminated, and configured to open the path of the stopper (31) while the telescopic adjustment is restricted. 本发明提供了一种转向系统(1)，其包括上部护套(3)、下部护套(4)、支承件(2)、锁定机构(5)和减震器(6)。支承件(2)支承下部护套(4)。锁定机构(5)切换伸缩调节的限制和限制的终止。上部护套(3)包括突出的止挡部(31)，该止挡部(31)构造成限定上部护套(3)在伸缩行程范围的一个端点处的位置。锁定机构(5)包括开闭部分(70)，该开闭部分(70)构造成在伸缩调节的限制被终止时进入止挡部(31)的路径，并且该开闭部分(70)构造成在伸缩调节被限制时打开止挡部(31)的路径。
