A spiral spring toy having a pulling string, a string windup spiral spring, first and second turning bodies, a driving spiral spring, a spiral-shaped guide groove and a floating means. The first turning body is connected with the driving spiral spring so that the driving spiral string biases the first turning body in a first rotational direction and rotation of the first turning body in a second rotational direction charges the driving spiral spring. The second turning body is connected with the pulling string and the string windup spiral spring so that the string windup spiral spring biases the second turning body in the first rotational direction. When the pulling string is pulled, the second turning body rotates in the second rotational direction and charges the string windup spiral spring. The spiral-shaped guide groove has an end portion and is provided on either the first or the second turning body. The floating means is provided on the turning body not provided with the spiral-shaped guide groove so that when the pulling string is pulled, the floating means contacts the end portion of the spiral-shaped guide groove causing the first and second turning body to rotate integrally in the second rotational direction. When the pulling string is released, the floating means floats through and copies the spiral-shaped guide groove so that the second turning body is restored before the first turning body and the string windup spiral spring is discharged before the driving spiral spring.
