<p>A reset rod 43 of a thermal overload relay is configured to be switchable between a manual reset position in which a reversal mechanism 21 is manually returned to an initial state prior to reversal by performing a pushing-in operation, and an automatic reset position in which a pushed-in state is held by a pushing and rotating operation from this manual reset position, and the reversal mechanism 21 is automatically returned to the initial position. In addition, axial runout restriction portions 17b, 17d, 51, 46 and 47, which restrict axial runout of the reset rod 43 when the reset rod 43 is held in the automatic reset position, are provided.</p> |
