AI Technical Summary
Technical Problem
The existing steering device is unnatural when the operator performs steering operations, which may cause operator fatigue.
Method used
A steering device is designed in which the base member rotates centered on a central axis and the central axis is arranged in an inclined manner from rear to front and downward. In addition, the transfer mechanism transmits the rotation of the front frame relative to the rear frame to the base member so that its rotation is adapted to the position of the handrail.
Benefits of technology
The elbow and wrist movements are made more natural during steering operation, reducing the operator's fatigue and improving the operation comfort.

Abstract
The base member (43) supports the operating lever (41). The transmission mechanism (45) transmits the rotation of the front frame (2a) with respect to the rear frame (2b) to the base member (43) to rotate the base member (43) about the base member shaft (45n). The base member shaft (45n) is disposed obliquely so as to be positioned downward from the rear toward the front.
