PROBLEM TO BE SOLVED: To provide the terminal arrangement of electrical machine capable of exhibiting screw up terminal function by engaging only with a stopper, without supporting one end of a coil spring.SOLUTION: A terminal arrangement of electrical machine includes a terminal screw 41 having a male screw part to which a stopper is attached, a terminal block 42 to which this terminal screw is screwed, a guide holding part 43 for guiding the stopper to advance and retreat freely for the terminal block at least when the terminal screw separates from the terminal block, and preventing withdrawal of the stopper at the terminal screw holding position, and a coil spring 45 placed in a spring arrangement part formed at one side part of the guide holding part. The coil spring includes coils 45a, 45b, first ends 45c, 45e extending from one end side of the coils, and coming into contact with a lateral face facing the guide part along the male screw part, and second ends 45d, 45f extending from the other end side of the coils, and coming into contact with a lateral part deviated from the male screw part in the face of the stopper facing the terminal block, in a state where the terminal screw is at the terminal screw holding position.SELECTED DRAWING: Figure 4 【課題】コイルばねの一端を支持することなく、当金のみに係合してねじアップ端子機能を発揮できる電気機器の端子装置を提供する。【解決手段】当金を装着した雄ねじ部を有する端子ねじ４１と、この端子ねじが螺合される端子板４２と、少なくとも端子ねじが端子板から離間するときから当金を端子板に対して進退自在に案内し、且つ端子ねじ保持位置で当金の抜け出しを防止する案内保持部４３と、この案内保持部の一側部に形成されたばね配置部内に配置されたコイルばね４５と、を備え、コイルばねは、コイル部４５ａ，４５ｂと、該コイル部の一端側から延長し、前記案内部に対向する側面に前記雄ねじ部に沿って接する第１端部４５ｃ，４５ｅと、前記コイル部の他端側から延長し、前記端子ねじが前記端子ねじ保持位置にある状態で、当金の端子板との対向面における雄ねじ部から外れた側方部に接する第２端部４５ｄ，４５ｆとを備えている。【選択図】図４
