Beschreibung
Zusammenfassung:	A shift apparatus (100) has a motor (130) that includes a rotational shaft (132), a moving mechanism that moves a manipulation knob (120) when the rotational shaft (132) rotates, rotation sensors (134) that detect the rotation amount of the rotational shaft (132), a position sensor (151) that detects the position of the manipulation knob (120), and a control unit (180). The control unit (180) includes a motor control unit (181) that rotates or stops the rotational shaft (132) so that the position of the manipulation knob (120) comes close to a target position, according to the rotation amount detected by the rotation sensors (134) and to the position detected by the position sensor (151). The control unit (180) also includes an abnormality detecting unit (183) that detects that at least one of the position sensor (151) and any one of the rotation sensors (134) is abnormal, according to the position of the manipulation knob (120), the position being indicated by the rotation amount detected by the rotation sensors (134), and to the positions indicated by the position sensors (151).
