Provided is a telescoping device capable of preventing a lower tubular body from jouncing during fixation by a fixing unit. A leg body (12) being a telescoping device includes an upper tubular body (21), a lower tubular body (22), and a fixing unit (31) that releasably fixes the lower tubular body (22) with respect to the upper tubular body (21). The fixing unit (31) includes an operation body (61) and a fixation body (62) . The fixation body (62) consists of an outer member (88), an upper inner member (92), and a lower inner member (94). On the outer member (88), inner peripheral upward inclined surfaces and inner peripheral downward inclined surfaces are formed. On the upper inner member (92), outer peripheral downward inclined surfaces are formed, and on the lower inner member (94), outer peripheral upward inclined surfaces are formed. |
