Abstract
An inflator unit provided on a main frame of a motorcycle is provided with an inflator case having an inflator stored therein. Gas generated by the inflator flows through the interior of the main frame and is supplied to the airbag. The inflator case includes the left and right case halves divided along the parting plane and joined with each other by two bolts and the internal space thereof narrows towards an exit opening in the funnel shape. The axis Li of the inflator is shifted to the side opposite from the exit opening with respect to the axis Lc of the inflator case. A main frame may be formed with an atmosphere communication hole for communicating the interior of the main frame with the atmosphere at the position near the inflator case so that the atmosphere is introduced through the atmosphere communication port into the interior of the main frame by the negative pressure generated when gas flows from the inflator to the airbag. Thus, a large-volume airbag can be deployed by a small-capacity inflator.
