LINEAR MOTION AND ROTATION DETECTOR, LINEAR MOTION AND ROTATION DETECTOR UNIT, AND LINEAR MOTION AND ROTATION DRIVE DEVICE

The objective of the present invention is to provide a linear motion and rotation detector with which a deterioration in the accuracy of detection of the rotational position of a moving body can be suppressed even if a rotary scale coaxial with the moving body is inclined as a result of inclination of the moving body. A linear motion and rotation detector 17 which detects displacement of an outputshaft 2 includes: a linear position detecting portion 20 provided with a linear scale 76 including a linear position detection magnetized pattern 79 on a circumferential wall 76a facing in the radialdirection, and a first magnetic detecting element 91 which faces the linear position detection magnetized pattern 79 from the radial direction and detects magnetic field variations; and a rotationalposition detecting portion 19 provided with a rotary scale 55 including a rotary position detection magnetized pattern 57 on a flat surface 55a facing in an axial direction X, and a rotational position detection magneto-resisti
