Beschreibung
Zusammenfassung:	A first vacuum motor includes a first pivoting shaft member, a bearing that rotatably supports the first pivoting shaft member, a disk disposed to be rotatable together with the first pivoting shaft member and having slits, a first bracket that is made of a non-magnetic material and supports the bearing, a recess formed in the first bracket to be dented in the axial direction, and a sensor unit disposed to face the disk in the axial direction via a thin wall formed by the recess. By the thin wall, the space where the sensor unit is disposed under the atmospheric pressure is isolated from the space where the disk is disposed under a reduced pressure lower than the atmospheric pressure.
