Airbag device

An airbag device comprising:

• an airbag which has a gas supply port;
• an inflator which supplies gas to the inside of said airbag through said gas supply port;
• a gas discharge state switching member which is attached to said airbag, and is configured to be changed over from a gas discharge state where the gas in said airbag is dischargeable to a gas non-discharge state where discharge of the gas in said airbag is suppressed when the gas discharge state switching member is pulled into the inside of said airbag;
• a connecting member whose one end portion is connected to said gas discharge state switching member and whose other end portion is connected to a portion of an inner peripheral portion of said airbag;
• and
• a vent hole which is formed at said airbag and through which the gas is discharged at a gas discharge speed slower than a gas discharge speed of said gas discharge state switching member in said gas discharge state, wherein
• an annular relay member which movably supports said connecting member along a longitudinal direction is attached to the inner peripheral portion of said airbag,
• said connecting member is bent by way of said annular relay member with said airbag in an inflated configuration, and
• an arranged position of said gas discharge state switching member, a connected position of said connecting member to the inner peripheral portion of said airbag, and an attached position of said annular relay member are disposed where avoid a portion of said airbag which comes into contact with an occupant in a regular posture state when the airbag in an inflated configuration receives the occupant.
