PROBLEM TO BE SOLVED: To provide a radio receiver for disaster prevention stock which is prevented from sinking in the water by reducing the weight of a main body, can be stored for a long time by eliminating the need to use a dry cell for which it is necessary to be exchanged periodically, is capable of confirming a tuning frequency of a radio station and easily confirms the tuning frequency when using the radio receiver.SOLUTION: A radio receiver for disaster prevention stock comprises an antenna, a radio receiver circuit 9, a display control circuit 10, a battery package 33 that becomes a power source of the circuits, and a speaker inside of a housing 1 having a sealed structure using a material of high waterproofness, and comprises a display 3 for displaying a tuning frequency, a channel selection switch 4 for selecting a frequency and a volume adjustment switch 5 for adjusting the volume of the speaker outside of the housing. The radio receiver includes a space inside of the housing in such a manner that the specific gravity as the entire radio receiver becomes 1 or less, and the battery package is an air cell.SELECTED DRAWING: Figure 2 【課題】本体重量が軽く水に沈むことが無く、定期的に交換が必要な乾電池を用いないために長期保存が可能であり、且つラジオ局の同調周波数が確認可能で、使用時に同調周波数の確認がしやすい防災備蓄用のラジオ受信装置を提供することを課題とする。【解決手段】防水性が高い材料を使用して密封構造とした筐体１の内部にアンテナと、ラジオ受信回路９とディスプレイ制御回路１０と、それらの回路の電源となる電池パッケージ３３と、スピーカーとを備え、筐体の外部には、同調周波数を表示するディスプレイ３と、周波数を選択するための選局用スイッチ４と、スピーカーの音量を調節するための音量調節用スイッチ５と、を備えているラジオ受信装置において、ラジオ受信装置全体としての比重が１以下になるように筐体の内部に空間を備え、電池パッケージは空気電池である防災備蓄用のラジオ受信装置。【選択図】図２
