Kind Code:

Abstract:
A puzzle piece, which is an arc-shaped piece body (10, 100) having a thickness. A circumferential surface (103) of the piece body (10, 100) protrudes to form a plurality of convex heads (13) and a plurality of concave bases (14). Each convex head (13) has a convex necking portion (131), and each concave base (14) is formed to have a corresponding embedding opening (141). When one piece (10) is connected to a concave base (14) of another piece (100) by a convex head (13), a first concave portion (132) and a second concave portion (133), which are adjacent to the convex necking portion (131) and are located at an inner side surface (101) of the piece, are formed by the convex head (13), and a third concave portion (142) and a fourth concave portion (143) are correspondingly formed by the concave base (14) at the inner side surface (101) of the piece, such that when the pieces are assembled into a puzzle, engagement of two adjacent pieces can be simple and convenient, and interference and obstructions are not likely to be generated.
