Claim:
1. A roller guide to be mounted to an elevating body, for guiding the elevating body along a guide rail extending in the vertical direction along a wall surface of a hoistway, the roller guide comprising: a roller rolling on the guide rail; and a guide frame rotatably supporting the roller, the guide frame comprising a single planar member made of a plastically deformable material having elasticity, the planar member comprising a frame mount surface portion to be mounted relative to the elevating body, a roller mount surface portion, and a plastically bent portion joining the frame mount surface portion and one end of the roller mount surface portion, the plastically bent portion being bent such that the roller mount surface portion is angled with respect to the frame mount surface portion and is separated from the elevating body, wherein the roller mount surface portion is not supported except by the connection of its one end to the frame mount surface portion at the plastically bent portion, whereby the roller mount surface portion comprises an elastically deformable cantilever structure mounted at the one end thereof to the frame mount surface portion, wherein the roller is rotatably mounted to the roller mount surface portion at a portion of the roller mount surface portion which is spaced from said end, such that the elastic deformation of the cantilever structure displaces the roller in a direction toward or away from the guide rail, wherein the guide frame comprises a stopper formed in proximity to the guide rail for regulating the elastic displacement of the roller mount surface portion, wherein the stopper is positioned in proximity to the guide rail such that the stopper interferes with the roller mount surface portion before the roller mount surface portion is plastically deformed.
