Abstract
An oscillator device includes at least one movable element supported for oscillatory motion around a rotational axis, and a damper member for applying a damping function to the oscillatory motion of the movable element, the damper member being provided along at least a portion of a locus plane defined by an edge of the movable element during oscillatory motion thereof, so that, based on a viscosity of a fluid which is present between the edge of the movable element and a portion of the damper member opposed to the edge of the movable element, the damping function is applied to applied to the oscillatory motion of the movable element.
