A cover body of a vehicle air bag apparatus, including a covering portion which is formed integrally with an interior panel body and which has a door portion defined by a tear seam formed in a back of the interior panel body, and, a backing portion joined to a back of the covering portion. The covering portion is made of polyolefin resin having a flexual elastic modulus of from 1500 to 3500 MPa, a tensile strength of from 17 to 40 MPa, an Izod impact strength of from 3.0 to 15.0 kJ/m2, and an elongation of 400% or less. The backing portion is made of thermoplastic olefin which is softer and has a greater elongation. The backing portion includes a reinforcing portion at a back of the door portion, a surrounding base at the back of the covering portion, and a hinge portion joining the reinforcing portion and the surrounding base.

A method for producing a steering wheel to which a liquid pressure transfer print is applied. In this method, by adjusting a transfer angle formed when the steering wheel is pressed onto a transfer film and selecting a part in a rim section at which the wheel begins to be brought into contact with the transfer film, a joint line of a transfer pattern is made invisible from the driver-side, and pattern-missing and pattern-distortion can be eliminated or decreased, resulting in a fine and precise liquid pressure transfer print being applied to the steering wheel. This method is characterized by that a front-face of the steering wheel is faced to the transfer film floated and advanced on a liquid-surface, the transfer angle is determined to be e.g., 30 to 45.degree., and first contact of the steering wheel with the transfer film occurs at a larger rim arc which is apart from portions where spokes are connected to the rim section, respectively.
