Claims

[Scope of utility model registration request]

a cylindrical base member; a cylindrical sliding member slidably provided inside the base member; a screw shaft rotatably provided on the base member along the sliding direction; A plurality of telescoping units formed integrally with the sliding member and consisting of a nut material screwed into the screw shaft are combined, with the sliding member in one telescoping unit being regarded as a base member in the other telescoping unit. and a driving force transmission means for transmitting driving force between the screw shaft and a screw shaft present in the sliding member when considered as a foundation member,
and a driving means is connected to either the screw shaft or the spline shaft, and the driving force transmission means is connected to a spline shaft provided on the base member in parallel with the screw shaft, and a spline shaft provided on the spline shaft and the base member. a rotational force transmitting means for transmitting rotational force between the splined screw shaft, a sliding gear fitted to the splined shaft so as to be slidable in the axial direction of the splined shaft, and a sliding gear when considered as a foundation member; A telescopic device comprising: a fixed gear that is integral with a screw shaft present in the member and meshes with the slide gear; and a guide member that prevents the slide gear and the fixed gear from coming out of mesh.
