備えてなることを特徴とする熱動過負荷継電器。 A release lever is housed in a case covered with a removable cover and is rotated via a shifter due to bimetal displacement caused by overcurrent, and a release lever is connected to the release lever and rotatably supported by the cam of the adjustment dial. A movable plate which is connected to the pressed adjustment link and the tension spring engaged by the release lever so that the line of action of the tension spring reverses beyond the dead center as the release lever rotates; a contact device having a movable contact that comes into contact with and separates from each of a flexible normally open fixed contact and a normally closed fixed contact; A return rod having a narrow recess with a step on the lower side on the front side for returning the operation of the contact, between the recess of the return rod and a protrusion provided on the cover that intervenes in the narrow part of the recess. A spring that returns the loaded and pushed return rod, is elastically integrated with the return rod, fits into a long hole provided in the cover to regulate the return operation, and is fitted into a square hole to automatically return. 1. A thermal overload relay comprising: a return device having a switching protrusion that is set to
