PROBLEM TO BE SOLVED: To provide a telescopic structure used for expansion and contraction of an object in which a user can expand/contract and store stationery, cosmetics, or daily necessaries, and manufacturing cost is low while manufacturing process is simple.SOLUTION: A telescopic structure used for expansion and contraction of an object comprises a housing 100, a telescopic body 200, an elastic body 300, a slide member 400, and a control member 500. An inside wall 110 of the housing 100 has a belt-like groove part 120. The telescopic body 200 is disposed inside the housing 100 and used for storing an object 1. A side wall of the telescopic body 200 has an annular groove part 220. The annular groove part 220 corresponds to the belt-like groove part 120 and is defined by an outer wall 221, a bottom face 222, and an inner wall 223. The elastic body 300 is connected to the housing 100 and the telescopic body 200. The slide member 400 slides between the belt-like groove part 120 and the annular groove part 220. The control member 500 is disposed in the telescopic body 200 and protrudes from the housing 100. |
