Claim:
1. A walking toy comprising: a body on which gravity center position adjusting members and paired legs are supported to be able to swing in a forward/backward direction; and a gearbox which has a crank mechanism for forcibly swinging the paired legs alternately forward and backward in a forcible swinging direction and which is mounted in the body, the paired legs having bottoms which are configured to be in contact with a floor surface and which are formed into curved faces curved in the forcible swinging direction, and the floor surface and the paired legs being constantly in contact with each other to allow the walking toy to travel by using the paired legs, wherein the gearbox is driven by a torsion coil spring and has a lever which rotates a drive gear of a gear train for transmitting rotation of the torsion coil spring to an output shaft for rotating the crank mechanism and which has a tip end portion protruding to an outside of the body, wherein the torsion coil spring is disposed between the lever and a frame of the gearbox and is configured to be twisted and wound by pushing down of the lever, wherein the lever is provided at a center in a left/right direction of the gearbox so as to be able to swing in a vertical direction and the gearbox is set in the body to be disposed at a center in the left/right direction of the body, wherein the left/right direction is perpendicular to the forward/backward direction, and wherein the lever has a disc portion at a center of rotation of the lever, the drive gear is formed at a portion of a peripheral face of the disc portion, a space for housing the torsion coil spring is formed on an inner side of the lever and the drive gear, one end of the torsion coil spring is housed in an internal space extending toward a tip end side of the lever, the other end of the torsion coil spring is in contact with the frame of the gearbox outside the internal space, and the torsion coil spring is twisted along a vertical plane orthogonal to the center of rotation of the lever at the center in the left/right direction of the body.
