Claims

[Scope of utility model registration request]

A main unit side mounting plate that has an extension portion extending forward from one end and is formed to be able to be attached to the main body of a range, etc., and can be attached in a stacked state from the side end of the door to the upper or lower surface. A door-side mounting plate is formed at one end of the horizontal plate part and pivoted to the extension part of the main body-side mounting plate and a stepped pin so as to be rotatable in the door opening/closing direction; The torsion spring is pivotally connected to the main body side mounting plate by a shaft pin, and one end is hooked to the main body side mounting plate, and the other end of the external torsion spring is hooked to the above shaft pin, so that the torsion spring rotates in one direction. The arm to be biased and the door-side mounting plate are rotatable in the door opening/closing direction around the stepped pin, and the rear end is configured such that the torsion spring biases the door in the closing direction when the door is closed. The catch arm has the other end of the arm and a catch arm whose front end is pivotally connected to the inner side of the horizontal plate part of the door-side mounting plate, and the front end of the catch arm has a front end pivoted when the door is opened. The door rotates around the pin and is movable diagonally forward in the door opening direction, and the door engages with the stepped pin due to the rotation biasing force of the torsion spring in the door opening direction, thereby making it possible to hold the door in the open position. A pivot hinge for a range, etc., whose front end is bent outward in the width direction of the door, and an engagement recess is provided on the outer side of the front end.
