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. At least that portion of the suction-adhering seal
which contacts the surface of the object vibrates in a manner which creates a
dynamic friction force to decrease the frictional force between the
suction-adhering seal and the surface of the object.
