ABSTRACT:
A wall surface suction-adhering and moving device including a supporting frame and at least one suction-adhering and moving unit. The device moves along the wall surface while suction-adhering thereto. The suction-adhering and moving unit includes a rotating member rotatably mounted on the supporting frame, and a sealing member for forming a pressure-reduction space in cooperation with the wall surface and the rotating member. The sealing member has an annular base portion fixed to the rotating member, a cylindrical main portion extending from the base portion in a direction away from the rotating member, and an annular contacting portion to be kept in contact with the wall surface. The suction-adhering and moving unit further includes a roller means rotatably supported on the supporting frame with its outer circumferential surface adapted to be pushed against the wall surface via the contacting surface of the sealing member, and a rotating driving source connected to either the rotating member and the roller means.
