Abstract
A venting device is provided at one side of a battery pack to discharge a venting gas generated in an inner space of the battery pack to the outside. The venting device includes a cylinder block configured to communicate with the inside of the battery pack and a venting gas flow path for discharging the venting gas to the outside, a piston assembly configured to move upward along an extension direction of the cylinder block by receiving a force caused by the increase of the internal pressure of the battery pack so that the inner space of the battery pack communicates with the venting gas flow path and a magnet unit installed in the cylinder block and configured to restrict upward movement of the piston assembly by a magnetic force so that the communication between the venting gas flow path and the inner space of the battery pack is blocked.
