An earth anchor bracket having curved parts with saw teeth is provided to preclude a pressure unit from being moved, and to increase internal pressure performance. An earth anchor bracket(100) comprises two side plates(110), a connecting member(120), and a pressure unit. The two side plates formed with curved parts(114) having saw teeth(115) are placed to be opposed. The connecting member connects the both side plates. The pressure unit has protrusions(134) tooth-engaged with the saw teeth of both side plates, and a through part(132). The pressure unit includes a cylinder member inserted between the both side plates, and a placing part formed outside the cylinder member.
