1. An airbag unit comprising:
an airbag; a cover part which covers the airbag; a fitting member fitted on a front side of the cover part and provided with a first locking part and a second locking part; and a fastening member which fastens the fitting member on a back side of the cover part, wherein the fastening member includes
a first fastening part which is inserted from a first side of the fitting member into the first locking part, to a first inserted position in a state in which the first locking part penetrates the cover part to a back side of the cover part,a second fastening part which is inserted from the first side of the fitting member into the second locking part, to a second inserted position in a state in which the second locking part penetrates the cover part to the back side of the cover part, anda connecting part which connects a base end part of the first fastening part and a base end part of the second fastening part, to form the fastening member into an approximate U-shape that fastens the fitting member on the back side of the cover part viewed in a direction generally perpendicular to the back side of the cover part, wherein external shapes and/or sizes of the first fastening part and the second fastening part are mutually different to prevent insertion to the first and second inserted positions, respectively, when the fastening member is inserted into the first and second locking parts at an incorrectly oriented setting, and wherein the incorrectly oriented setting of the fastening member includes at least one of the first fastening part being inserted into the second locking part, the second fastening part being inserted into the first locking part, and the first and second fastening parts being inserted from an incorrect, second side of the fitting member opposite to the first side.
