薄型化に貢献できる。(Effects of the invention) According to the invention, a guide portion for guiding the insertion of an electronic element in which a base plate is arranged opposite to a circuit board and a holding member is provided on the circuit board side of the base plate, and a guide portion opposite to the circuit board. Since it is comprised of an elastic part that elastically holds the side wall of the electronic element provided on the side, vibration and impact of the electronic element can be prevented during normal assembly.
Furthermore, since the holding portions are formed on both sides of the main plate, the distance between the main plate and the board can be narrowed, which can contribute to making the entire case thinner.
