Claims

[Scope of utility model registration request]

The cover is pivoted on a bracket so as to be rotatable to open and close, a drive arm connected to the cover, and a drive section for reciprocating the arm, the drive section causing the drive arm to reciprocate. The opening/closing mechanism has a structure in which the cover is rotated to open and close by using a torsion coil spring made of an elastic material;
Torsional coil springs made of a shape memory alloy are provided so that the legs open and close when a certain temperature is reached, and the coiled portions of these torsional coil springs are fitted onto the shaft that supports the cover, Both legs of the torsion coil spring are respectively attached to the drive arm and the bracket, a means is provided for heating the shape memory alloy torsion coil spring by energizing it, and an electromagnet is attached to the bracket. A permanent magnet is connected to the drive lever, so that when the cover is in the open position, the permanent magnet and the electromagnet come into contact with each other, and when the cover is closed, the permanent magnet and the electromagnet are separated. An opening/closing mechanism characterized by:
