The light-transmitting cover 59 includes a receiving portion 67 and an attachment portion 68 for the LED support portion 65 </ b> A, and an LED (light emitting diode) 63 and a holding member 65 are attached to the side surface of the refrigerator compartment 3 of the ceiling plate 61. It becomes covered with a lighting device.

  The illuminating device having such a configuration may be arranged at the center of the ceiling of the refrigerated room 3, but in consideration of the case where the lighting effect of the left and right parts of the refrigerated room 3 is reduced by articles stored in the refrigerated room 3. As shown in FIGS. 10 and 11, such a lighting device can be arranged on the left and right of the ceiling of the refrigerator compartment 3. In this case, considering the commonality of components, ease of assembly, and the like, the ceiling plate 61 is approximately sized across the width of the refrigerator compartment 3, and the LED (light emission) of the above configuration is provided on the left and right portions of the ceiling plate 61. A diode) 63 and a holding member 65 are attached, and the left and right LEDs (light emitting diodes) 63 and the holding member 65 are covered with a single light-transmitting cover.

  Each of the above embodiments is a cold storage having the refrigerator compartment 3, the freezer compartment 5, the vegetable compartment 6 and the like of the above-described form, but the present invention can be applied to various forms of the cold storage, The present invention is not limited to this, and is effective when applied to various cooling storages within the technical scope of the present invention.
