Abstract: An electrical connection box includes a block that houses a plurality of electronic components, a housing body in which an internal space for housing the block is formed, and engagement portions that are provided between the block and the housing body and fits the block to the housing body. The engagement portions include a first engagement portion corresponding to the one direction end of the block in a specific direction and a second engagement portion corresponding to the other direction end of the block in the specific direction. In the first engagement portion, an inclined surface of the guide receiving portion is formed. When the block is inserted into the housing body in the insertion direction, the inclined surface is formed by cutting out an end where the guide receiving portion faces a guide piece in the insertion direction.

Abstract: An electric connection box includes a frame and a cover. A side wall of the cover has an insertion wall portion inserted into an inner side of an outer wall of the frame in an axial direction, and the insertion wall portion has a thick portion thicker than an adjacent portion in the insertion wall portion. In a case where the thick portion is placed outside the outer wall, a first engagement element of the outer wall and a second engagement element of the side wall are displaced in a thickness direction of the thick portion and engagement between the first engagement element and the second engagement element becomes impossible. The thick portion has an inclined surface that guides the thick portion to the inner side of the outer wall in abutting on the outer wall in the axial direction.

Abstract: An electrical connection box includes a housing having a temporary fixing projection. The temporary fixing projection includes a locking portion and a plate spring portion. The locking portion is provided with a locking claw projecting toward an outside in a radial direction. The plate spring portion includes a flat surface. In a temporary fixing state where the temporary fixing projection is inserted into a temporary fixing hole of an attachment panel, a locking surface of the locking claw of the locking portion faces a facing surface in an insertion direction. In the temporary fixing state, the plate spring portion is elastically deformed toward an inside in the radial direction. The flat surface of the plate spring portion is in contact with a contact surface and applies, to the attachment panel, a restoring force toward the outside in the radial direction.
