Provided is a rotation detection device including: a power supply unit configured to output constant power supply; a rotation sensor unit configured to output a detection signal that depends on rotation of a vehicle; a controller configured to calculate on-time rotation information on the vehicle, which is information at a time when an ignition switch is on, to control a motor; and a calculation unit configured to calculate off-time rotation information on the vehicle by intermittently supplying a power supply voltage to the rotation sensor unit when the ignition switch is off, update a set value of an intermittent interval so that the set value becomes smaller when the off-time rotation information contains information indicating rotation of a motor for the vehicle, and otherwise update the set value of the intermittent interval so that the set value becomes larger.
