Reference numeral 12 denotes a case. The case 12 houses the liquid crystal display element 9 and the circuit board 10. The case 12 is made of a translucent resin (for example, polycarbonate),
A male screw 13 that is screwed with a female screw of a retaining ring described later is provided. The circuit board 10 is fixed to the case 12 by screws 14. Reference numeral 15 denotes an outer case, and the outer case 15 is made of a resin (for example, ABS). The outer case 15 is fixed to the case 12 with screws (not shown).

Reference numeral 16 denotes a housing. The housing 16 has a concave portion 17 for accommodating a battery described later. A female screw 18 (second screw) is provided on the inner periphery of the concave portion 17. Reference numeral 19 denotes a battery. The battery 19 has a flat shape and is inserted through an opening 20 of the housing 16. Reference numerals 21 and 22 denote terminal plates. The terminal plates 21 and 22 are fixed to the housing 16 by screws 23 and connected to the cathode and anode of the battery 19, respectively. Reference numeral 24 denotes a lid, and the lid 24 is attached to the opening 20 of the housing 16. The lid 24 is made of a colorless and transparent translucent resin (for example, polycarbonate), and is provided with a male screw 25 (first screw) screwed to the female screw 18 of the housing 16.

Reference numeral 26 denotes an annular sealing member (sealing member). The annular sealing member 26 is provided between the opening 20 of the housing 16 and the lid 24 to seal the opening 20. The annular sealing member 26 is made of an elastic material such as rubber, and may be of the same color (for example, black) as the housing 16, but if it is colored in a different color, it is more visible.
