An infant's swing is disclosed. The swing is driven by an electric power to automatically operate the swing. The frame is A-shaped in a side view, and a pair of oscillation shafts are secured to a pair of securing bars respectively, the securing bars being installed in the peak portions of the frame 12 respectively. A pair of magnet boxes are provided to contain a pair of securing bars and a pair of electromagnets in each of them, and an oscillator is disposed between each pair of the electromagnets. An electric power is supplied alternately to the electromagnets to alternately magnetize them, thereby making the oscillators swing leftward and rightward.

1. A swing comprising: an A-shaped frame arbitrarily set on a ground and having a pair of symmetric peaks; and a swing seat supported to a pair of supporting bars, the supporting bars being supported to a pair of securing bars respectively; the swing further comprising: a pair of oscillation shafts respectively and integrally bent down from the securing bars, for oscillating to left and right together with the pair of the supporting bars respectively; a pair of oscillators secured to lower ends of the oscillation shafts respectively; a pair of springs installed between the frame and the oscillation shafts respectively, for furnishing an elastic force; and a pair of electromagnets and disposed at left and right sides of each of the oscillators. 2. The swing as claimed in claim 1, wherein the electromagnets and alternately gain and lose magnetic fluxes owing to a pair of left and right sensors, when the oscillator swings leftward and rightward. 3. The swing as claimed in claim 1, further comprising: a control panel for controlling a time period and velocity of the swing. 4. The swing as claimed in claim 1, wherein during a standstill of the swing, the control panel senses crying of an infant to activate the swing and to output music.
