Electric junction box

The invention provides an electric junction box which can easily assemble a module to a framework. The electronic junction box (1) comprises the framework (2) which is provided with a frame-shaped peripheral wall (20), and the module (3) which is inserted into the inner side of the peripheral wall (20) from an opening part (20b) of the peripheral wall (20) and assembled to the framework (2). The framework (2) is provided with four locking parts, and the module (3) is provided with four locked parts clamped and stopped by the locking parts. Furthermore, the framework (2) is provided with a guide structure (6), and the guide structure (6) guides the locked parts from a side of the opening part (20b) to the corresponding locking parts. The guide structure (6) comprises a pair of ribs (60), and the ribs (60) are connected with the inner surface of the peripheral wall (20) and extends from a position near the opening part (20b) to the locking parts, so the locked parts are located between the opening part (20b) and the locking parts in a freely sliding manner. The guide structure (6) is also used for enhancing rigidity of the framework (2).
