電流調整機構。 A release lever that rotates due to the curvature of the heat element connected to the main circuit and reverses the reversal spring to open and close the contacts, and a release lever that is formed integrally with a case made of insulating material and is supported by a shaft that protrudes from the case and is controlled by an adjustment dial. An operating current adjustment mechanism for a thermal overload relay, comprising: an adjustment link that is rotated to adjust the rotation angle of the release lever according to the magnitude of the required operating current to determine the degree of curvature of the heat element; A connecting part is formed integrally with the case and has a width that is approximately the same as the diameter of the shaft, and connects the shaft and the side wall of the case, and a part of the hole of the adjustment link into which this shaft is inserted is adjusted so that the width of the connecting part is greater than the width of the connecting part. An operating current adjustment mechanism for a thermal overload relay, characterized by having a notch that is large enough to accommodate the required rotation of a link.
