摘要： An air supply device comprises an enclosure, a pump and a flow path switching unit. The flow path switching unit includes a pedestal part, a rotating part having an enclosure interior space communication portion and a groove portion, and a drive unit. The enclosure includes an air supply port, an air discharge port, and at least one object connection port. The pedestal part includes at least one first hole that is communicated to the at least one object connection port, and a second hole that is communicated to the air discharge port. The enclosure interior space communication portion is communicated to the air supply port through an interior space of the enclosure. The groove portion is separated from the enclosure interior space communication portion.

摘要： An air supply device comprises a pump and a flow path switching unit. The pump is configured to supply air. The flow path switching unit includes a pedestal part forming a flow path from the pump to at least one object, a rotating part rotatably provided with respect to the pedestal part to switch the flow path, and a sheet member disposed between the pedestal part and the rotating part. The sheet member has a first layer and a second layer that are stacked in a direction directing from the rotating part to the pedestal part. The first layer has a smaller elastic modulus than the second layer. The second layer has a smaller friction coefficient than the first layer.
