するという問題点があった。Since the spring buffer (5) is installed at the center of the mounting base (2), a large bending moment is generated at the center of the lower surface of the supported elevating body (4). For this reason, the elevating body (4
) A strong member must be placed on the bottom surface. Further, the mounting base (2) also needs to be strong like the lower surface member of the elevating body (4). Furthermore, since the spring shock absorber (5) is installed in a free-standing state, there is a problem in that the design takes buckling into consideration, resulting in an unnecessarily large size.
この発明は、かかる問題点を解決するためになされたも

造費、据付費を低減することができる。In the elevator spring shock absorber configured as described above, when the elevating body (4) descends excessively, it is supported by the elevating body (4) and the spring shock absorber (6) via the guide (4a). For this reason, when the spring shock absorber (6) is used to buffer the elevating body (4),
A large bending moment will not be generated on the lower surface member and the mounting base (2) (these members can be made simple). Function-oriented design is possible and can be downsized.Furthermore, there is no need for fasteners or processing for the independent installation of the spring buffer (6).Therefore, manufacturing costs and installation costs are reduced. can do.
