PROBLEM TO BE SOLVED: To make toy movement interesting by providing, under a figure shaped in an animal, etc., a rotating body, which can roll freely and has a built-in heating or cooling medium, and by making it possible to show traces on the contacting surface of a reversible thermochromism sheet through a projecting part for showing traces provided on the rotating body surface. SOLUTION: A rotating body 4 is arranged to attach and detach freely on a fixed part 31 provided on a lower opening of a figure 3, which is made to imitate the appearance of a duck. The rotating body 4 is formed by pasting, on the circumference of a cylinder-shaped member, a metal member imitating footmarks of a duck as a projecting part 412 and a thermal insulating member. As a walking surface, a reversible thermochromism sheet 6 is arranged on a surface of a porosity sheet made of synthetic resin having independent bubbles as a base 61. The reversible thermochromism sheet 6 is constituted by laminating a reversible thermochromism layer 62, including microcapsule pigments of reversible thermochromism, which contain reversible thermochromism material that changes color to blue at lower than 15 deg.C, and to red at 15 deg.C or higher. And pieces of ice as cold medium is contained in the rotating body 4 to show footmarks on the sheet 6, when a toy 1 is moved. |
