The detection section has: a cam section which is provided on a pivot shaft, includes a predetermined cam surface, and is formed so that the radial distance from the center of the pivot shaft to the cam surface varies circumferentially; and a proximity sensor which detects the position of the cam surface which varies as the pivot shaft pivots.
