The main cover is configured to cover the opening area.

Provided is an electrical junction box including an attachment body that is assembled to an electrical junction box main body through a rotating operation, and having a novel structure that makes it possible to suppress vibration of the attachment body relative to the electrical junction box main body and advantageously ensure the stability of conduction between the electrical junction box main body and the attachment body. An electrical junction box includes an electrical junction box main body having a mount portion and a separate attachment body removably attached to the mount portion, a pair of connectors are respectively provided on opposing surfaces of the mount portion and the attachment body are connected to each other, and a vibration suppressing member is between the opposing surfaces, the vibration suppressing member suppressing vibration of the attachment body by exerting a frictional force on the opposing surfaces.

Provided is an electrical connection cassette with which it is possible to freely expand a device and add functions in accordance with the size of free space. An electrical connection cassette is provided with: a circuit board; and first connection terminals and second connection terminals mounted on the circuit board and having terminal shapes that can be engaged with each other. In a state with a terminal connection direction oriented in a predetermined direction with respect to the circuit board, the first connection terminals are disposed on the side of one main surface of the circuit board, and in a state with a terminal connection direction oriented in a direction parallel to the predetermined direction, the second connection terminals are disposed near the other main surface of the circuit board.

An electric connection box includes a frame, a lower cover that covers the lower surface of the frame, and at least one block that is attached in the frame and disposed at a position along a peripheral wall of the frame. An electric wire that is connected to a component attached to the block out of the blocks is drawn horizontally from the block toward inside the frame.
