The present invention relates to a double earthquake-proof type distribution box having an up and down refraction buffer means. The double earthquake-proof type distribution box includes: a box type case (110); a distributing board (120) received inside the case (110); and an up and down refraction buffer means (130) interposed between a lower surface (115) of the case (110) and the ground (G), and interposed between the case (110) and the distributing board (120). A lower end portion of the distributing board (120) is supported by a bracket (113) fixed to an inner part side surface of the case (110); the up and down refraction buffer means (130) is interposed between the bracket (113) and the distributing board (120); and the up and down refraction buffer means (130) is interposed between the distributing board (120) and the inner part side surface of the case (110). Therefore, the distribution box doubly buffers a shock of an earthquake when the earthquake happens. |
