Abstract
The present technology relates to a battery cell jig for fastening bolts with uniform pressure when fixing a battery cell between first and second plates by applying the same rotating force to a plurality of bolt fastening units. The battery cell jig includes first and second plates arranged to face each other, n bolt fastening units, where the n is an integer equal to or greater than 2, a rotating member which is installed on one surface of the first plate or the second plate and is installed on an opposite side of a surface where the first and second plates face each other, and a driving unit which transmits rotating force of the rotating member to each of the n bolt fastening units.
