To reduce the capacity of a rotation actuators or rigidity of a crank link mechanism or enhance the durability of the rotating actuators or the crank link mechanism.

The rotation actuators of a plurality of heald frame driving apparatuses are divided into a first and a second groups located in one of the left and right directions of each heald frame and the other and on the upstream side and the downstream side in the warp yarn moving direction. The rotating shafts of the rotation actuators are arranged in a state extending in the warp yarn moving direction in a frame. The rotation of each rotation actuator is set so as to lower an eccentric part of the crank when the heald frame is lifted from the lower dead center position.
