Claims

[Scope of utility model registration request]

A support plate 2 installed at a corner 1a of the front edge of the driver's cab 1 rotatably supports a column 4 provided with a mirror 3, and an arm 5 protruding from an end 4a of the column 4 is attached to a column 4. One end 6a of the tension spring 6 is loosely engaged with the support plate 2, and the other end 6b of the tension spring 6 is loosely engaged with the support plate 2. One end 7a of the memory alloy coil spring 7 is loosely locked, and the other end 7b is connected to the other end 6b of the tension spring 6.
The support plate 2 is installed at a position opposite to the mounting position of the support plate 2.
An automobile characterized in that a heating element 9, which is loosely engaged with the coil spring 7 and generates heat by being energized by operation of a switch 8 provided in the driver's cab 1, is provided in the vicinity of the shape memory alloy coil spring 7. Rotation mechanism using mirror shape memory alloy.
