Abstract
A gripping head of a handling apparatus grips objects, such as lipsticks or the like by means of the inflated surface of the tube thereof. A fluid inlet is formed on top of the hard body, and a fluid path is formed in the hard body. The outer cylinder open at the lower end thereof is so fixed on the hard body as to contain the latter, and the above-mentioned tube open at both ends thereof is fixed at both the ends to the lower outside end of the outer cylinder and the hard body or to the upper and lower outer ends of the hard body. The object is caught by the catching head when the tube is inflated inwardly as the fluid such as air is supplied into the space between the tube and outer cylinder or into the inside space of the tube through the fluid path from the fluid inlet.
