PROBLEM TO BE SOLVED: To provide an airbag device for knee protection capable of exactly pushing an edge surface of a connection port part side of an inflator by means of a protrusion piece upon actuation even when the protrusion piece is small.SOLUTION: In an airbag device for knee protection, a connection port part 55 is arranged on one edge side by an inflator 51. An opening 38R for a connector capable of connecting the connector to the connection port 55 is formed on a lateral wall 36R of a case 28. A protrusion piece 44R for coming-off prevention of the inflator 51 is formed on a periphery of the opening 38R for the connector is formed. A guide part 40R which guides the inflator to a coming-off position by means of the protrusion piece 44R while sliding with an outer circumferential portion of the connection port part 55 side of the inflator 51 is formed. The guide part 40R is arranged so as to be opposed on the shaft orthogonal direction side of the inflator 51 and includes a guide surface 41R which can reduce a mutual separation distance toward the moving direction side of the inflator 51 upon nut clamping of a bolt. |
