The invention provides an airbag apparatus for a motorcycle that can easily be mounted after assembly. To achieve this, an airbag apparatus for a motorcycle having a steering handle (8) mounted so as to be capable of rotating with respect to a head pipe (39) mounted at the front end of a main frame (6) is provided. An airbag mounting member (45) is mounted so as to extend from the main frame (6) toward the front of the vehicle body across the central axis of rotation (41) of the steering handle (8) and a top bridge (43). An airbag module (47) is mounted on the airbag mounting member (45). The upper portion of the airbag module (47) is covered by a covering member (48) including a weakened portion.
