An airbag module of a driver's seat is provided to distribute high pressure gas evenly by restricting early deployment of an airbag with tension in taking yarn away from a lap, and to protect a driver against sudden deployment of the airbag by breaking the lap along a tear line in spreading the lap. An airbag module of a driver's seat of a vehicle is composed of an airbag housing fixed to a center of a steering wheel and opened in an upper part, an airbag cover covering the upper part of the airbag housing to form an exterior, an inflator installed in the airbag housing to generate high pressure gas at a collision, a separate plate inserted to the inflator, an airbag(60) having an inlet end(60a) opened, folded and combined with the separate plate by a retainer, a textile lap(62) surrounding the airbag and having an H-shaped tear line(62a) to deploy the airbag, and an airbag deployment pressure distributing unit injecting high pressure gas by restricting early deployment of the airbag in flowing gas.
