Also in the present embodiment, the side frame members 32 are provided so that the distance between the upper chord member 33 and the lower chord member 34 extends from the inclined part C to the upper and lower horizontal parts A, B. Wider than the space between the upper chord 33 and the lower chord 34 of the side frame Because of the configuration, the strength of the main frame can be maintained without impairing the advantage of installation.

The present invention is not limited to the above embodiment. For example, an additional side frame for reinforcement is retrofitted above a normal side frame to form a two-stage side frame, The vertical width of the side frame (the interval between the lower chord of the normal side frame and the upper chord of the additional side frame) may be widened from the portion to the upper and lower horizontal portions.

This configuration forces ⁵ ^ which is less deflection of the main frame in the transport of S. force, single data one is the condition, it is possible to carry side frame body to retrofitting individually.

When the escalator is installed on the stairs, if there is room between the escalator (main frame) and the stairs, the upper frame material and the lower chord material of the side frame body are only provided at the upper side as in the above-described embodiment. Instead of widening the gap between the upper and lower chord members of the side frame body, the strength of the main frame may be maintained. For example, in the case of the escalator shown in Fig. 1, the space between the upper chord member 4 and the lower chord member 15 of the side frame is from the middle of the upper horizontal part A to the vicinity of the intermediate landing 4 of the inclined part C. Can be spread downward.

As described above, in each of the above-described embodiments, the side frame is made of the upper chord material, the lower chord material, and the vertical member. However, if the strength and the weight can be maintained to some extent, the configuration is not limited to this configuration. Instead, for example, the side frame may be formed using an I-beam. Even in this case, the distance between the upper side and the lower side of the side frame, that is, the width between the upper side and the lower side of the side frame is increased from the inclined portion to the upper and lower horizontal portions. The same effects as the embodiment can be obtained.
