Summary:A curtain airbag device where an airbag main body provided along a roof side rail is deployed in the form of a curtain inside the vehicle compartment by operation of an inflator. The airbag main body includes a first expansion part disposed at a position overlying a center pillar and supplied with gas by operation of the inflator during deployment; a second expansion part disposed to the rear of the first expansion part and supplied with gas from the first expansion part; and a gas communication part providing communication between the first expansion part and the second expansion part. The gas communication part is provided above a seatbelt interference region where the deployed airbag main body interferes with the seatbelt. When the vehicle is subjected to an external impact and the airbag main body expands, gas flows from the first expansion part to the second expansion part.
