TRAVELING DOLLY AND TRACK-TYPE VEHICLE

摘要

This traveling dolly (6) is provided with: steered wheels (12); a dolly body (11) for supporting the steered wheels (12); a guide device (13) rotating when subjected to a reaction force from a guide rail (3); a steering mechanism (14) for applying a steering force to the steered wheels (12) utilizing the reaction force applied to the guide device (13); and an assist mechanism (15) for applying an assist steering force to the steered wheels (12), the assist steering force assisting the steering force applied by the steering mechanism (14). The assist mechanism (15) is provided with: a first operation arm (31) pivoting together with the steered wheels (12) in the direction in which the steered wheels (12) are steered; a second operation arm (32) rotating about an rotation axis (O4) relative to the dolly body (11) in response to the rotation of the guide device (13); and an elastically deformable section (33) connected to the first operation arm (31) and the second operation arm (32) and elastically deformable.
