Abstract: An assembly unit for a toy capable of preventing a pair of side walls thereof surrounding a recessed part for engagement from cracking. A plurality of part units are connected to each other through a projected part (109) for engagement and the recessed part (111) for engagement. The projected part (109) for engagement comprises a base (113), a plate-like part (115) extending in a direction apart from the base, and an engagement part side extension part (117) formed at the tip of the plate-like part. The recessed part (111) for engagement comprises the pair of side walls (121) with flexibility integrally having, at its tip part, engaged part side extension parts (119) for stopping the extraction of the engagement part side extension part (117) and a bottom wall (123) connecting the base parts of these pair of side walls to each other.

Abstract: The present invention provides a transformable toy capable of transformations which are more unpredictable than those according to the prior art. A neck section (19) is constructed to be extended and contracted in a direction where a first to fourth components (35-41) are arranged. The first component (35) is fixed to a fixed section of the transformable toy. The first component (35) and the second component (37) are connected by a slide type connecting mechanism. The second component (37) is fitted in the first component (35). The second to fourth components (37-41) are connected by a rotary type connecting mechanism. All or most of the second to fourth components (37-41) are received in the first component (35).

Abstract: To provide an assembly unit for a toy capable of storing unused engaging section in a part unit thereof. An arm part (13) of the toy comprises a rotating member (50) rotating about a rotating shaft (55) provided in the body (14) thereof. The rotating member (50) has an engaging section (53), which is used for connecting the rotating member to a second part unit (23), which is connected to the arm part (13), and a hand (necessary member) (51). When a separate member (23) is connected to the arm part (13), the hand 51 is stored in the body 14 and the engaging section (53) is exposed to the outside of the body (14). When the separate member (23) is not connected to the arm part (13), the engaging section (53) is stored in the body (14) and the hand (51) is exposed to the outside of the body (14).
