A ventilation path (21) is formed in 5), and the suction port (22) opened in the suction pad section (12) and the inside of the flexible telescopic tube (5) are formed by this ventilation path (21). The bypass path (17) derived from the connection block (15) is also in communication with the ventilation path (21). On the other hand, a flexible ventilation pipe (7) disposed between the vacuum motor (10) and the flexible telescopic pipe (5) has a plurality of intermediate portions mounted on the swing arm (3) so as to be freely movable. It is supported by running rollers.

When it comes into contact with the peripheral surface of the cylindrical body (11), the suction pad (12)
Since the suction port (21) opening to the outside is shielded from the outside, the pressure in the suction pad portion (12) and in the flexible telescopic tube (5) becomes a negative pressure state, and the suction pad portion (12) The liquefied petroleum gas cylinder (1) is sucked and held, and at the same time, the flexible telescopic tube (5) shrinks to lift the liquefied petroleum gas cylinder (1).

なって、液化石油ガスボンベ(１)は一定高さまで吊り上
げられてその高さを維持することになる。In this case, a bypass valve is provided in the bypass passage (17).
Since the outside air flows through (20), the flexible telescopic tube
The outside air from the bypass passage (17) is continuously supplied into (5), and the amount of contraction is maintained at a predetermined amount by maintaining the negative pressure in the flexible telescopic tube (5) constant. As a result, the liquefied petroleum gas cylinder (1) is lifted to a certain height and maintains that height.

なって、ボンベの吊り上げ高さが低くなる。When the opening amount of the bypass valve (20) is operated to the closed side, the amount of outside air taken in from the bypass passage (17) decreases, and the pressure in the flexible telescopic tube (5) is further reduced. Therefore, the amount of contraction of the flexible telescopic tube is increased, and the cylinder can be lifted higher. Meanwhile, the bypass valve
When the valve opening of (20) is operated to the open side, the amount of outside air taken in from the bypass passage (17) increases, the degree of pressure reduction in the flexible telescopic tube (5) decreases, and the flexible telescopic tube contracts. The volume is also smaller and the lifting height of the cylinder is lower.

に防止することができる。When the vacuum motor (10) stops due to a power failure or the like, negative pressure in the flexible telescoping pipe (5) and the flexible ventilation pipe (7) causes the outside air intake through the bypass valve (20). Although outside air is taken in from 19), since the bypass valve (20) is throttled, outside air flows in slowly and the suspended liquefied petroleum gas cylinder (1) descends slowly. In this case, since the weight of the liquefied petroleum gas cylinder (1) acts in the direction in which the flexible telescopic tube (5) is extended, it acts on the side that reduces the pressure in the flexible telescopic tube (5), and finally reduces the adsorption holding power. And the gas cylinder can be prevented from falling as much as possible.

In the above embodiment, the swinging arm is attached to the column (2) standing on the floor.
Although the description has been given of the case where (3) is supported so as to be able to swing horizontally, the swing arm (3) may be supported so as to be able to swing horizontally on the wall surface of the building.

Is supported via a flexible telescopic tube, and the suction port opened to the suction holder and the internal passage of the flexible telescopic tube are connected to each other through a ventilation path, and the bypass is branched to a bypass path derived from the ventilation path. Since the valve is arranged and the internal passage of the flexible telescopic tube is connected to the vacuum motor through a flexible ventilation pipe via an air filter, the suction holder can be brought into contact with the peripheral side surface of the cylinder. The inside of the flexible telescopic tube is in a negative pressure state, the flexible telescopic tube contracts, and the cylinder can be lifted. In other words, according to the present invention, since the suction of the cylinder and the lifting and lowering of the cylinder are performed by one vacuum motor, the number of devices that cause the cylinder to fall is small, and the cylinder falling accident can be prevented as much as possible. And
When the cylinder is moved laterally with the cylinder lifted, the cylinder can be moved to any position by swinging the swing arm and moving the swing arm in the longitudinal direction.

Acts so as to suppress the sudden decrease in the attraction force, so that the cylinder can be lowered slowly without dropping suddenly.
