Why the steering wheel comes back to its main position automatically to some extent after the car has been turned...??

The front tires have caster, meaning that the pivot axis is angled and/or offset so that the contact patch is "behind" the pivot axis, and the side load due to cornerning creates a steering torque on the tires that tends to center the steering.
