Supporting Device for Driving Battery

A supporting device for a driving battery mounted on an electronic vehicle, the supporting device comprising:

• a battery-side bracket comprising a front bracket that has a squared C-shaped cross section and covers a front edge part of the driving battery, a rear bracket that has a squared C-shaped cross section and covers a rear edge part of the driving battery, a right bracket that has a squared C-shaped cross section and covers a right edge part of the driving battery, and a left bracket that has a squared C-shaped cross section and covers a left edge part of the driving battery, the battery-side bracket being attached to the driving battery;
• and
• coupler brackets that are coupled one to each of an intersection part of the front bracket and the right bracket, an intersection part of the front bracket and the left bracket, an intersection part of the rear bracket and the right bracket, an intersection part of the rear bracket and the left bracket, and that couple the driving battery to the electric vehicle via the battery-side bracket, wherein
• at least one of an upper face part and a lower face part of at least one of the right bracket and the left bracket that are serving as side edge part bracket has a particular region being in a form of a trapezoid having an upper base facing in a direction of the driving battery and being a region at an intermediate region in a longitudinal direction sandwiched by coupling parts coupled with the coupler bracket, one or more lightening holes being formed within the particular region.
