[Problem] To provide a lock that can be reduced in size and the number of components compared to the prior art. [Solution] A lock (100) is provided with a cylindrical member (10), an igniter (20) having a portion fitted into the cylindrical member (10), and a holder (30) that holds the cylindrical member (10) and the igniter (20) and is fixed to a portion of a bag holder (40). The cylindrical member (10) is a bottomed cylindrical member having an opening provided at the igniter (20)-side end, and is a member in which a bottom portion (11), a cylindrical portion (12), a flange portion (13), and an operating pin (14) are integrally molded. A fragile portion 11a, which is an annular recessed portion, is provided on the inner surface of the bottom portion 11 at a position facing the outer peripheral portion 14a of the rear operating pin 14. The fragile part 11a breaks due to a pressure wave received during operation of the igniter 20.
