<p>The following are supported on the upper surface of a support base: a first bearing stand in which a first bearing is positioned; and a second bearing stand in which a second bearing is positioned and which is positioned at a distance in the horizontal direction from the first bearing stand. A rotating shaft which is rotatably positioned in the first and second bearings is supported by the first and second bearing stands. The support base is provided with a projecting section that projects upward from the upper surface of the support base. The first and second bearing stands are in contact with side surfaces of the projecting section causing the bearing stands to be positioned in relation to the support base in a manner such that the axial direction of the rotating shaft is a prescribed direction.</p> |
