Abstract
A position detection apparatus detects a position of a target in a predetermined direction. One end of a swinging member contacts the target, and the other end contacts a moving member. Sensors are arranged to output signals corresponding to a position of the moving member that corresponds to a position of the moving member. A detection unit detects the position of the target based on the output signals of the sensors. Measured parts are disposed on the moving member along loci of measuring positions of the sensors so that the sum total of the output signals becomes an even number. The detection unit determines that any one of the sensors failed in a case where the sum total of the output signals of the sensors is an odd number.
