A torsion device in which one end of a coil portion formed by spirally winding a spring wire into a cylindrical shape is engaged with a fixed member, and the other end is engaged with an operating member that applies a torsional force to the coil portion. An engaging part made by extending and folding back the spring wire is brought into contact with the middle of the coil part of the coil spring, and a locking member capable of engaging with the engaging part is provided on the fixing member, and the torsion stroke is constant. A torsion coil spring device characterized in that the engaging portion contacts the locking member only at a portion of the coil portion, thereby changing the effective length of the coil portion. 2. The locking member is arranged at a distance from the engaging portion at the front in the twisting direction, and the retaining portion comes into contact with the locking member during the twisting stroke, thereby increasing the effective length of the coil portion. The torsion coil spring device according to claim 1, which is characterized by being shortened. 3 Applying a twisting force to the fixed end side of the coil part in advance,
A utility model characterized in that the engaging part is in contact with the locking member, and the engaging part is separated from the locking member in the middle of the twisting stroke to lengthen the effective length of the coil part. A torsion coil spring device according to claim 1.
