To protect cooling means even in an overload state.SOLUTION: A commodity storage device having a circulation fan 30 installed at a ventilation duct 12 at the outside of a storage chamber 11 of a case main body 10, and making air circulate between the storage chamber 11 and the ventilation duct 12 at driving, and a cooling unit 20 for cooling air which is made to circulate by the drive of the circulation face 30, and cooling a commodity while storing it in the storage chamber 11 comprises: an in-chamber temperature sensor 16 for detecting an internal temperature of the storage chamber 11; and a control part 40 for driving the circulation fan 30 at low rotation which is obtained by reducing a rotation number up until a preset set time elapses by determining an overload state when the internal temperature detected by the in-chamber temperature sensor 16 is equal to or higher than a pre-decided reference temperature.SELECTED DRAWING: Figure 2 【課題】過負荷状態においても冷却手段を保護すること。【解決手段】ケース本体１０における収納庫１１の外部の通風ダクト１２に設置され、かつ駆動する場合に収納庫１１と通風ダクト１２との間で空気を循環させる循環ファン３０と、循環ファン３０の駆動により循環させられる空気を冷却する冷却ユニット２０とを備え、収納庫１１に商品を収納しつつ冷却する商品収納装置であって、収納庫１１の内部温度を検出する庫内温度センサ１６と、庫内温度センサ１６で検出された内部温度が予め決められた基準温度以上である場合、過負荷状態であると判断して、循環ファン３０を、予め設定された設定時間が経過するまで回転数を低減させた低回転駆動させる制御部４０を備えている。【選択図】図２
