An airbag includes a body and a redirecting cloth that is composed of a sheet material having flexibility and disposed inside the body. The redirecting cloth includes an inlet port for taking in an inflation gas; one or more outlet ports that release the inflation gas as flown from the inlet port towards predetermined regions of the body; and a sew region that sews first and second terminal edges of the sheet material together. Each of the first and second terminal edges of the sheet material includes a turned-and-sewn region that has been turned inward and sewn. At least a part of the sew region is formed by sewing terminals of the turned-and-sewn regions together.

A steering wheel includes a ring part, a boss part, spoke parts that connect the ring part and the boss part, a steering wheel main body that includes a core and a covering layer covering the ring part and the spoke parts in the vicinity of the ring part of the core, and a heater unit that warms up at least a portion of the ring part. The heater unit includes a heater main body that includes a base material having a sheet body and a linear heater, and is disposed in a state where an outer face side of the heater main body is covered by a cover layer of the covering layer and a connection part that connects the linear heater and a terminal of a lead wire for power feeding.

An airbag cover includes a ceiling wall portion provided on a steering wheel, and covered an airbag. The ceiling wall portion has an attaching door portion and a non-attaching door portion opened to the left and the right, causing a predetermined fracture portion to facture by the inflating airbag. The attaching door portion has an ornament retained on an attaching seat. In the predetermined fracture portion, the common portion positioned at the center of the right and left door portions has a bypass portion on the circumference of the attaching seat. The attaching door portion is slightly opened toward the rear.

A wrapping sheet is to be torn by the inflation of an air bag. Since attachment shafts, used to hold the folded air bag in position, are projected from the air bag, an engagement portion of the wrapping sheet is fitted on the attachment shafts, and the shape of a folding completed body of the air bag is maintained. The wrapping sheet includes not only the engagement portion, but also a coupled portion to be connected to the air bag, and a folding form control portion, which has an auxiliary engagement portion to be fitted on the attachment shafts. When the auxiliary engagement portion is fitted on the attachment shafts, the shape of the air bag that is being folded is adjusted.
