ABSTRACT:
A check valve60is formed by a pair of the valve body portions61. Ends of the valve body portions61that are close to an upper inflation portion EU are joined to a communication passage wall51by an outflow-side joint portion41. Each valve body portion61includes a flexible portion64that is located in the vicinity of the outflow-side joint portion41and between the outflow-side joint portion41and a lower inflation portion EL. The front edges of the valve body portions61are joined to the communication passage wall51by a first edge joint portion67. The first edge joint portion67also functions as a wall joint portion63that joins the communication passage walls51to each other. The rear ends of the valve body portions61are joined to each other by a second edge joint portion68, which extends along the flowing direction of inflation gas. An auxiliary joint portion69is located between the first edge joint portion67and the second edge joint portion68, and in the vicinity of the second edge joint portion68. The auxiliary joint portion69joins the valve body portions61to each other. The auxiliary joint portion69also functions as a rigid portion65, which is harder to flex than the flexible portion64. The rigid portion65extends along the flowing direction of the inflation gas.
