According to the above-described conventional boarding steps, the boarding steps themselves are part of forming the frame of the vehicle body, and therefore require a predetermined strength to cope with heavy loads. . Therefore, it has been difficult to configure a boarding step in consideration of the riding comfort of the operator, that is, a boarding step in which even if the vehicle picks up irregularities on the road surface, its vibration is difficult to transmit to the operator.

[0005] Further, since low-lift trucks are often used in narrow places indoors, such as in the above-mentioned factories, they are made as compact as possible and there is almost no space inside the main body. For this reason, even if it is considered that an elastic member is embedded in the lower part of the boarding step, it is very difficult to insert those constituent members. Also, when trying to embed an elastic member under the boarding step and raising the step surface of the boarding step to make room for it, there is a problem that the operator will have difficulty getting on and off this time. Met.

Accordingly, an object of the present invention is to solve the above-mentioned problems, and to provide a low-lift truck capable of improving the riding comfort of an operator.
