Abstract
Disclosed is a solenoid configured so that vibration and noise in energization can be reduced. The solenoid is configured to use magnetic action in energization of a coil to drive, in an axial direction, a core at least including a first magnetic resistor. The solenoid includes a shaft attached to the core, and bearings supporting both end portions of the core. The solenoid further includes a second magnetic resistor configured to generate force for moving at least the core in a radial direction by the magnetic action.
