Abstract
The elevator comprises guide rails extending along a height of a shaft, a car and/or a counterweight moving upwards and downwards in the shaft and being glidingly supported on the guide rails. A stop block is attached to at least one guide rail in order to prevent movement of the car and/or the counterweight beyond the level of the stop block. The stop block comprises a buffer attached to a bottom plate. The buffer comprises a slot receiving a guide portion of the guide rail. The bottom plate supports the buffer on the guide rail.
