Provided are an agitator and an agitating hook provided therein. The agitator includes a rotary shaft rotatably installed in a reactor, rotor blades installed at an outer circumference of the rotary shaft and rotated with the rotary shaft to agitate a material therein, and an agitating hook constituted by a pair of members spaced apart from each other at an inner wall of the reactor and through which the rotor blades pass. Here, a gap between the agitating hook is larger at an outlet port through which the rotor blade leaves than at an inlet port through which the rotor blade enters. Since a pressure is uniformly applied from the inlet port through which the rotor blade enters to the outlet port through which the rotor blade leaves, a torsional moment applied to the agitating hook is minimized. Therefore, it is possible to improve durability of the agitating hook and increase reliability of products.

Agitator and agitating hook provided therein

Disclosed is a battery pack including a battery module array having battery modules which are arranged in a lateral direction in two or more rows, each of the battery modules configured with battery cells or unit modules, each of which has two or more battery cells mounted therein, are stacked in a state in which the battery cells or the unit modules are erected vertically, a base plate on which the battery modules are stacked in a vertically erected state, a pair of main members provided at the front and rear of the battery module array, opposite ends of each of the main members being fastened to an external device, a pair of end plates disposed in contact with the front and rear of the battery module array such that the lower end of each of the end plates is fixed to the base plate, and supporting bars.
