<P>PROBLEM TO BE SOLVED: To provide a direct-acting generator which prevents a decrease in the quantity of generated power due to magnetic saturation. Ž<P>SOLUTION: This generator includes a fixed yoke 2 and a mobile yoke 3, which reciprocates along the fixed yoke 2, and for the mobile yoke 3, permanent magnets 4, the magnetic poles of whose same polarity face out in opposite directions of reciprocation, are built in both ends in the direction of reciprocation. The fixed yoke 2 includes an electromagnetic member 6 for auxiliary power generation. The member 6 has a coil 5, which is wound at right angles to the direction of motion of the mobile yoke 3, an inner sidewall 2a, which covers the side, close to the mobile yoke 3, of the coil 5, and an outer sidewall 3b, which covers the side, far from the mobile yoke 3, of the coil 5. The member 6 faces the mobile yoke 3 from the opposite side of the fixed yoke 2, and approaches or breaks from the permanent magnet 4, accompanying the reciprocation of the mobile yoke 3.
