The lower frames 10b and 10c are the floorboards 1.
It has a length dimension in the same direction shorter than the depth dimension of 0a.

Next, an elevator car floor support according to an embodiment of the present invention will be described with reference to FIG. As shown in FIG. 3, the support base 1 for the elevator car floor is the floor board 1
0a is placed on the base 2, the first shift preventing member 2a and the second shift preventing member 2b which are provided on the upper surface of the base 2 with a predetermined space therebetween, and one end is rotatably attached to the base 2 by a hinge 3b. It is configured to have a connecting member 3 which is connected and has a plurality of connecting holes 3a formed on the other end side. A trolley 4 used in combination with the support base 1 is configured by attaching a plurality of pairs of wheels 5 such as casters to the lower surface of the base 4a in the front and rear, and a flat upper surface of the base 4a on which the base 2 of the support base 1 is mounted. It has a flat bottom surface.

FIGS. 1 and 2 are a side view and a front view showing a transportation state of a car floor using a support base of the elevator car floor. As shown in FIGS. 1 and 2, a pair of elevator car floor supports 1 are arranged at both widthwise ends of a car 7 with a car floor 10 in an upright position, and a carriage 4 is arranged at a lower portion thereof. Used. The depth direction end surface 101a as a car in the floor plate 10a is placed on the base 2, and the first shift preventing member 2a provided on the base 2 is mounted.
The depth direction end of the lower frame 10b is placed on the lower frame 10b, and the depth direction end face 101a of the floor plate 10a is sandwiched between the first shift preventing member 2a and the second shift preventing member 2b. Thereafter, the connecting member 3 while rotating the free end side in the depth direction of the lower frame 10b, i.e. the coupling hole 3a of the connecting hole 10 d and the coupling member 3 formed in the height direction intermediate portion in FIG. 2
