Abstract
An exemplary roller guide assembly for an elevator device comprises a shaft supporting a roller for engaging a guide rail, a shaft support member that receives the shaft therein, and a member inserted between the shaft and the aforementioned shaft support member. According to this invention, because the shaft is supported by the shaft support member via the elastic member, when the rollers are biased in the horizontal direction by the guide rail, the member limits the shaft from turning relative to the shaft support member.
