Claim:
An engagement mechanism, which engages a first assembly part with a cooperating second assembly part, the first assembly part having a pair of concave portions and the second assembly part having a pair of engagement portions, wherein the concave portions correspond in position to the engagement portions respectively, the engagement mechanism comprising: a pair of pivot members provided in the first assembly part to freely pivot therein, each of the pivot members comprising a projecting portion which extends outwards of a corresponding one of the concave portions of the first assembly part, an endmost portion of each of the projecting portions having a double-wedged surface; and a pair of elastic members arranged between the first assembly part and the pivot members providing elastic force for maintaining a corresponding one of the projecting portions extending outwards from a corresponding one of the concave portions of the first assembly part and engaged with a corresponding one of the engagement portions of the second assembly part, wherein when the engagement mechanism is fitted to the second assembly part, each of the double-wedged surfaces abuts against the corresponding one of the engagement portions, wherein each of the engagement portions is a concave groove, and wherein the first assembly part comprises a pair of protruding posts for coupling one end of a corresponding one of the elastic members, and wherein each of the engagement portions is slided into the corresponding one of concave portions without rotating the first assembly part and the second assembly part for assembling the first assembly part and the second assembly part, and each of the engagement portions is pulled away from the corresponding one of concave portions without rotating the first assembly part and the second assembly part for disassembling the first assembly part and the second assembly part.
