Claims

[Scope of Claim for Utility Model Registration] (1) A tubular housing whose one end opening serves as a hose insertion port is provided at a suitable location on the stand body, and the negative pressure inside the tubular housing is provided at the other end opening of the tubular housing. A suction hose storage device, characterized in that an on-off valve that closes the opening is swingably provided, and a limit switch that is activated when the on-off valve comes into contact is provided at a position opposite to the on-off valve. (2) The suction hose storage device according to claim 1, wherein the base end of the opening/closing valve is pivotably attached to the tubular storage body. (3) The suction hose storage device according to claim 1, wherein a rubber seal is provided at the opening of the tubular storage body.
