Abstract
A wall surface suction travel device includes a first travel unit, a second travel unit, a joint mechanism, and an elastic mechanism. The travel units are aligned along a travel direction and are each configured to travel on a wall surface while being suctioned on the wall surface. The joint mechanism couples the travel units together such that the travel units can pivot relative to each other on a pivot axis extending in a direction that is perpendicular to both a wall surface facing direction and the travel direction. The elastic mechanism includes a first end fixed to the first travel unit, a second end fixed to the second travel unit, and an elastic member configured to be elastically deformed when one of the travel units pivots relative to the other travel unit and a distance between the first end and the second end is shortened.
