However, the distance between the guide rails is determined by the size of the elevator car (or the balance weight in the case of the elevator shock absorber support device on the counterweight side), and the main beam and the rail mounting plate are fixed by welding. Therefore, a support device having different main beam lengths according to the distance between the guide rails is required. For this reason, since the parts cannot be shared as the types of support devices increase, there is a problem that the cost increases. In addition, the main beam is considerably large because it is provided between the guide rails, which is inconvenient for transportation, storage, and installation.

In the figure, the fixed base 6 having a U-shape is arranged so that the opening thereof faces downward, and the plate 4 is arranged substantially parallel to the upper surface 6a at the outer lower part of the opposite side surface of the fixed base 6. One end of each is fixed by welding. A mounting plate 3 having a guide rail mounting surface 3a substantially perpendicular to the upper surface 6a of the fixing base 6 is provided on one side surface that is orthogonal to the side surface to which the plate 4 is fixed and has a release portion. The guide rail fixing portion 1 is constituted by the fixing base 6, the plate 4 and the mounting plate 3. The guide rail fixing portion 1 is disposed below each of the pair of guide rails 2 disposed so as to face each other in the elevator hoistway, and is fixed by anchor bolts 9b provided on the bottom surface of the hoistway pit. . Further, the guide rail 2 is placed on the upper surface 6a of the guide rail fixing portion 1 so that the back surface faces the guide rail mounting surface 3a, and a flange 13 is provided by a fixture 13 provided on the guide rail mounting surface 3a. The part is fixed to the hoistway pit by being pinched. In addition, one end of an end joint member 7b having an L-shaped cross section is fixed to each side surface of the fixing base 6 to which the plate 4 is fixed by welding with bolts and nuts. A plurality of fixing holes 10b are provided at equal intervals on the other end of the material 7b. Like the end connecting member 7b, the center connecting member 7a having an L-shaped cross section is provided with a plurality of fixing holes 10a at both ends at equal intervals, and both end portions provided with the fixing holes 10a are provided at both ends.
