インジケータ。A cylinder chamber in which the piston is slidably housed, a connection port that opens at one end side of the cylinder chamber and communicates with a negative pressure chamber between the filter and the electric blower in the vacuum cleaner body, and the cylinder chamber. The cylinder chamber has a ventilation port that opens near the other end and communicates with the atmosphere, and a leak air intake that opens in the side wall of the cylinder chamber and communicates with the atmosphere, so that the position of the piston can be confirmed from the outside. includes a cylinder in which at least a portion of a side wall is transparent, the piston in the cylinder chamber has a leak air passage part and is connected to an end of the cylinder on the vent side by a spring, and the piston when the leak air intake is displaced by a predetermined amount or more toward the connection port against the spring force of the spring;
An indicator for indicating the amount of dust suction for a vacuum cleaner, wherein the leak air passage portion and the connection port communicate with each other to form a leak air path.
