<<Prior Art>> It has been known to raise and lower an elevating column in a buried cylinder in a prop for a car stop or the like (see Japanese Utility Model Application No. 58-54422).

《Problem that the invention aims to solve》 However, in this case, even when the lifting column is raised and stopped, the cross section of the lifting column is circular and does not change at all, so the lifting column does not respond to the rise and fall of the lifting column. It is troublesome to check the position of the locking part provided in the lift, and it requires complicated operations such as having to press the lifting column many times to confirm that the lifting column is properly locked. be. In addition, the shape of the lift column rising above the ground remains the same no matter what direction it is viewed from, making it undesirable as a car stop in a parking lot used by today's young people who prefer fashion. There were drawbacks such as the inability to visually check from a distance from the lift column whether or not the lift was being carried out reliably.

This invention is a solution to the above-mentioned problems, and is aimed at providing a support for a car stop or the like that is convenient to use.
