Abstract: When a sub board is detached from a main board, a movable part is slid toward the main board. At this time, a wedge part of the movable part intrudes between a main part and an engagement part to cause elastic deformation to an extending part of the engagement part, thereby releasing engagement between the engagement part and an engagement receiving part. Even if an operator removes his/her hands from the movable part, the movable part is not displaced away from the main board, and the state in which the engagement part is disengaged from the engagement receiving part is thus maintained. Consequently, after sliding the movable part to release the engagement between the engagement part and the engagement receiving part, the operator can proceed to the next operation of pulling out the sub board.
