PURPOSE:To make a movable body shiftable at will not only at a flat but at places such as a staircase, a wall surface, a ceiling, inside and outside the piping, etc., by installing such a wheel as being capable of suction or detachment in a tip part of an arm of the movable body. CONSTITUTION:In a movable body proper, each of expandable and bendable sideway arms 2 expanding sidewise each is installed in its front part and symmetrical parts via an arm driving part 1a, and from the underside, an expandable and bendable lower arm 3 expanding beneath is installed therein via the driving part. At each tip of these arms 2 and 3, there is provided with each of wheels 14 capable of suction or detachment by means of vacuum suction pressure. Each of these wheels 14 is erectable vertically and also tiltable horizontally, while each wheel 14 has a function for a suction plate. In time of making the movable body travel, the wheel is erected upright, rotating each wheel for traveling and in time of suction movement, the wheel is tilted down and traveling takes place by making each wheel act as the suction plate. |
