Claims (1)

[Claims for Utility Model Registration] (1) The mainspring device is forcibly rotated in a direction opposite to the direction in which the mainspring device is running while the drive wheel connected to the mainspring device is in contact with the running surface. In a spring-driven toy with a winding structure, a plurality of spring devices each having a different biasing force are configured to be connectable to the toy body via a common connection mechanism, and the rotational force is transmitted between the two. The input rotating member on the toy main body side and the mainspring shaft on the spring device side, which control the input rotation member, are arranged such that one end surface thereof protrudes from the outer surface of its own case, and when the spring device is coupled to the toy main body. The spring-driven toy is characterized in that it is configured to be able to sink from the protruding position toward the inside of the case by the coupling operation. (2) The spring-driven toy according to claim 1, wherein either the input rotating member or the spring shaft is supported by spring means within its own case. (3) The input rotating member is capable of rotating together with the input gear that is gear-coupled with the drive wheel and the input gear, and is capable of rotating only itself during vertical displacement. Utility model registration claim No. 1, which consists of a shaft member that can be independently displaced in one direction on the shaft, and a pressure spring that can bias the shaft member in a direction opposite to the direction of displacement of the shaft member. 1
The wind-up driven toy according to item 1 or 2. (4) The mainspring device is attached to the toy so that the rotating surface of the mainspring is parallel to the running surface. Claims 1 to 3
The wind-up driven toy according to any one of the following paragraphs. (5) The common connection mechanism is comprised of a fitting structure between a square hole formed in the output shaft of the mainspring device and a square shaft provided on the toy body side. The wind-up driven toy according to any one of the following paragraphs. (6) Any one of claims 1 to 5 of the utility model registration claims, wherein the plurality of spring devices each having different biasing forces have the same spring case shape and size. The wind-up driven toy described in . (7) The toy vehicle is a toy mini-car, and the spring device is removably attached to the engine mounting part of the toy mini-car. The clockwork-driven toy described. (8) The mainspring device has a mainspring case whose external appearance resembles the external appearance of a real automobile engine.
The wind-up driven toy described in Section 1.
