To realize fine adjustment of a pressing force of a processing tool when processing a glass plate end surface.SOLUTION: An end surface processing device 1 comprises: an oscillative arm member 4 for supporting a grindstone 2; a servo motor 5 which generates drive power in order that the grindstone 2 presses an end surface E of a glass plate G; and a linkage 6 which transmits drive power of the servo motor 5 to the arm member 4. The linkage 6 comprises: a first link member 6a which can be oscillated by the servo motor 5; and a second link member 6b which is so connected to the arm member 4 and the first link member 6a respectively as to be capable of oscillating. The end surface processing device 1 is so configured that in the state that the grindstone 2 contacts the end surface E of the glass plate G, an angle θ1 between a direction Ar orthogonal to a longer direction A of the first link member 6a and a longer direction B of the second link member 6b becomes smaller than an angle θ2 between a direction Cr orthogonal to a longer direction C of the arm member 4 and the longer direction B of the second link member 6b.SELECTED DRAWING: Figure 2 【課題】ガラス板の端面を加工する際に、加工具の押圧力の細かな調整を実現する。【解決手段】端面加工装置１は、砥石２を支持する揺動可能なアーム部材４と、砥石２がガラス板Ｇの端面Ｅを押圧するための駆動力を発生するサーボモータ５と、アサーボモータ５の駆動力をアーム部材４に伝達するリンク機構６と、を備える。リンク機構６は、サーボモータ５によって揺動可能な第一リンク部材６ａと、アーム部材４及び第一リンク部材６ａのそれぞれに揺動可能に連結された第二リンク部材６ｂと、を備える。端面加工装置１は、砥石２がガラス板Ｇの端面Ｅと接触した状態で、第一リンク部材６ａの長手方向Ａの直交方向Ａｒと第二リンク部材６ｂの長手方向Ｂとのなす角θ１が、アーム部材４の長手方向Ｃの直交方向Ｃｒと第二リンク部材６ｂの長手方向Ｂとのなす角θ２よりも小さくなるように構成されている。【選択図】図２
