A seam of a seat front part is joined to a clip inside a groove on a surface of a seat pad, and tucked into the groove. In a vehicle seat having an airbag unit, inside the seat corresponding to a seam of a seat side part, a webbing is provided along a side part in an area corresponding to the airbag unit on an inner side of the side part. The webbing is sewn together with a seat cover at the seam of the seat side part, and is joined to a non-woven fabric between a seam and the clip in the seat front part on the seam side.
