A first restriction wall and a second restriction wall extend from the base in the first direction, spaced at an interval in the second direction, and sandwich the functional component in the second direction. A coupling wall extends from the base in the first direction and couples the first restriction wall to the second restriction wall in the second direction. Two guide walls are spaced in the third direction and sandwich the functional component in the third direction. Pressing portions sandwich the functional component together with the coupling wall in the first direction.
