Abstract: A device capable of suction-adhering to and moving along the surface of an object includes a pressure reduction housing, a suction-adhering seal mounted on the pressure reduction housing and defining a pressure reduction space in cooperation with the pressure reduction housing and the surface of the object, and a vacuum generator for discharging a fluid from the pressure reduction space to the outside of the pressure reduction space. The device suction-adheres to the surface of the object by the pressure of an ambient fluid acting on the pressure reduction housing owing to the difference in fluid pressure between the inside and the outside of the pressure reduction space. The device is moved along the surface of the object by driven wheels which engage the surface.

Abstract: A traveling device having a frame means, and a moving means mounted on the frame means and moving on a travel surface, the moving means comprising a plurality of wheels, or a plurality of endless tracks each including a plurality of belt pulleys is disclosed. The frame means includes a main frame, a pair of oscillating frames arranged on both sides of the main frame, and a connecting frame disposed on one end portion side of the main frame. A central portion of the connecting frame is coupled to the main frame via a monoaxially oscillating joint means, both end portions of the connecting frame are coupled to one end portion of each of the oscillating frames via an omniaxially oscillating joint means, and the other end portion of each of the oscillating frames is coupled to both side portions of the other end portion of the main frame via a biaxially oscillating joint means.
