An elevator car or elevator counterweight comprising:

• at least one elevator safety device that comprises:
• a housing attachable to the elevator car or to the elevator counterweight of an elevator system, the housing comprising a passage that allows a guide member to pass through;
• a brake shoe attached to the housing and located on a first side of the guide member passing through the passage;
• a spring assembly arranged on a second side of the guide member passing through the passage and comprising at least one leaf spring, the spring assembly having a fixed end, which is fixed to the housing, and an opposite free end, which is not fixed to the housing;
• a roller;
• wherein the spring assembly extends at an angle with respect to the guide member, defining a tapered region between the guide member and the spring assembly, wherein the opposite free end of the spring assembly is arranged closer to the guide member than the fixed end of the spring assembly;
• wherein the roller is, at least in an activated condition of the at least one elevator safety device, located within said tapered region defined by the spring assembly and the guide member;
• wherein the roller is movable along the spring assembly towards the opposite free end of the spring assembly into a wedged condition between the spring assembly and the guide member;
• wherein a portion of the spring assembly adjacent to the opposite free end of the spring assembly is configured for being bent away from the guide member by the roller, when or as the roller moves towards the opposite free end of the spring assembly;
• and
• a stopper, which is located at a position spaced beyond the opposite free end of the spring assembly in a direction away from the fixed end and outside of the tapered region, and which is configured for preventing the roller from moving beyond the opposite free end of the spring assembly.
