This elevator car includes: a car frame having a pair of vertical frames and a lower frame linking lower ends of the pair of vertical frames; a floor support beam supporting a car floor and supported on the lower frame; an under-car pulley disposed below the car floor; a pulley support member fixed to the floor support beam and rotatably supporting the under-car pulley; and a linking member linking the vertical frames and the floor support beam. The elevator car has a structure in which an upward force exerted on the pulley support member and the floor support beam by a main rope that is wound around the under-car pulley is received by the linking member and the vertical frames.

Elevator car and elevator

An elevator passenger car allows enhancement of rigidity of a lower beam with a simple configuration while suppressing an increase in the number of components, and includes an upper beam disposed at an upper side, a pair of vertical frames having upper ends connected to both ends of the upper beam, a lower beam disposed between lower ends of the pair of vertical frames while having both ends connected, and a pair of underfloor side surface beams which are mounted and connected onto both ends of the lower beam while extending orthogonal thereto. The elevator passenger car has a car room disposed at a part defined by the upper beam, the pair of vertical frames, and the lower beam that is mounted on the pair of underfloor side surface beams. An underfloor side surface beam reinforcing member is provided for each of the pair of underfloor side surface beams.
