Abstract: A member of the present invention is provided with: a base material 12 having a low thermal conductivity; a heating element 13 that is routed to a surface of the base material 12; and a covering material 11 having a high thermal conductivity, and covering the heating element 13 and the base material 12, in which the base material 12 includes a positioning portion 21 adapted to position the heating element 13, and the covering material 11 is formed so as to compensate each other in cooperation with the heating element 13, and closes at least a partial range in a region between an exterior face and the surface of the base material 12.

Abstract: An airbag device includes an airbag, an adjusting unit capable of adjusting an aperture efficiency of at least one vent hole, a tether belt whose one end is connected to the adjusting unit, and a holding unit for hooking another end of the tether belt. In case where the inflating airbag needs to exert a small reactive force, the adjusting unit is made in a full-opened state at a development early stage with the other end being held by the holding unit and then made in a half-opened until a development final stage with the other end being kept held by the holding unit. In case where the inflating airbag needs to exert a large reactive force, the adjusting unit is made in a full-closed state from a development start to the development final stage with the other end being released from the holding unit.
