The present invention relates to an up/down movement guide roller for a lift and a method for manufacturing the same. The purpose of the present invention is to prevent a contact member, which is made of thermosetting rubber, from being spaced from a connection member, which is made of steel, and being fractured as a result of a long period of use, to suppress vibration, noise, etc. during up/down movements of the lift, and to eliminate a lubricant, such as grease, which is used to improve the driving efficiency, thereby preventing environmental contamination that would otherwise be caused by the lubricant. The purpose is accomplished by an up/down movement guide roller for a lift and a method for manufacturing the same, the up/down movement guide roller for a lift comprising: a hollow shaft having a through-hole formed at the center thereof such that a coupling shaft, which is fixed to a frame of the lift, can penetrate the center portion, thereby being configured to be able to be inserted ...
