PROBLEM TO BE SOLVED: To provide an engagement structure capable of improving the reliability of an engaging mechanism.SOLUTION: An engagement structure 100 comprises: a block 5 having first side surfaces 5a and 5b and second side surfaces 5c and 5d and holding electronic components; a cover 4 having first inner wall surfaces 41a and 42a opposed to the first side surface and second inner wall surfaces 43a and 44a opposed to the second side surface and integrally covering the block and the electronic component; an engaging mechanism having a convex engaging portion provided on one of the first side surface and the first inner wall surface, and a concave engaging portion provided on the other of the first side surface and the first inner wall surface; and a projection portion 55, provided on one of the second side surface and the second inner wall surface, being in contact with the other side of the second side surface and the second inner wall surface in a state where the engagement mechanism is engaged, and pressing the other surface to prevent the first side surface and the first inner wall surface from relatively moving to each other in a direction in which the first side surface and the first inner wall surface get away from each other.SELECTED DRAWING: Figure 7 【課題】係合機構の信頼性を向上させることができる係合構造を提供する。【解決手段】係合構造１００は、第一側面５ａ，５ｂおよび第二側面５ｃ，５ｄを有し、電子部品を保持するブロック５と、第一側面と対向する第一内壁面４１ａ，４２ａ、および第二側面と対向する第二内壁面４３ａ，４４ａを有し、ブロックおよび電子部品を一体に覆うカバー４と、第一側面および第一内壁面の一方に設けられた凸状係合部と、第一側面および第一内壁面の他方に設けられた凹状係合部と、を有する係合機構と、第二側面および第二内壁面の一方の面に設けられ、係合機構が係合している状態で第二側面および第二内壁面の他方の面に接触して当該他方の面を押圧し、第一側面と第一内壁面とが離間する方向に相対移動することを抑制する突起部５５と、を備える。【選択図】図７
