Elevator passenger car and elevator having same car

An elevator passenger car comprising an upper beam disposed at an upper side, a pair of vertical frames having upper ends connected to both ends of the upper beam in a longitudinal direction, 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 is mounted and connected onto the both ends of the lower beam while extending in a direction orthogonal to the lower beam,

• the elevator passenger car having a car room disposed at a part defined by the upper beam, the pair of vertical frames, and the lower beam, the car room being mounted on the pair of underfloor side surface beams,
• wherein an underfloor side surface beam reinforcing member is provided for each of the pair of underfloor side surface beams so as to be reinforced,
• wherein each of the pair of underfloor side surface beams has a U-shaped section cut in a direction orthogonal to the longitudinal direction, having an upwardly directed open section;
• and
• the underfloor side surface beam reinforcing member has a U-shaped section cut in a direction orthogonal to the longitudinal direction, having a downwardly directed open section to be opposite to each of the open sections of the pair of underfloor side surface beams.
