Patent attributes
A passenger conveyor includes a semi-fixing mechanism, which restrains movement of a truss in a direction toward one floor and releases the restraint of the movement of the truss in the direction toward the one floor, and a truss-position recovery mechanism, which moves the truss in the longitudinal direction with respect to the one floor to set a dimension between the truss and the one floor to a preset specified dimension before the truss is moved in the longitudinal direction with respect to another floor when a separating force in a direction in which the truss is separated from the one floor is exerted between the truss and the one floor after the restraint of the movement of the truss in the direction toward the one floor is released.
