Abstract
In a dust suction apparatus, a flexible sheet is provided on the open top of a channel body which communicates with an exhaust section. An opening support member is provided in a box-shaped slider, and separates a portion of the sheet from the open top of the body so that the sheet hermetically closes the open top except at the portion, and openings are made between the side edges of the portion of the sheet and the side portions of the body, and communicate with a dust generating part. The slider is disposed on the channel body so that the slider can be moved relative to the body along the longitudinal direction thereof as the slider remains in hermetic sliding contact with the body. The dust and the air are conducted from the dust generating part into the channel body through the openings between the portion of the sheet and the side portions of the body without elongating or compressing an exhaust tube as the part is moving.
