摘要： An airbag includes plural bag portions respectively including two sheet members attached to each other, and a welded portion at which the sheet members being in contact with each other are attached to each other. The welded portion includes a communication hole penetrating the sheet members to communicate the bag portions, and a rib portion arranged radially outward of the communication hole, the rib portion protruding in the thickness direction from a welded surface of the welded portion. The rib portion includes an annular rib surrounding the communication hole, and a cutout portion provided at the annular rib. The rib portion includes plural radial ribs arranged radially inward of the annular rib, the plural radial ribs radially surrounding the communication hole and extending in a radial direction of the communication hole. At least one of the radial ribs is arranged at a position radially away from the communication hole.

摘要： A method for manufacturing an air bag includes forming a bag portion surrounded by a welded portion extending in an annular shape by pressing at least one welding mold against two sheet materials arranged to be stacked from a stacking direction of the sheet materials. The welding mold is pressed against the sheet materials to form the welded portion including a welding bead portion protruding to an inside of the bag portion between the sheet materials. A pressing surface of the welding mold against the sheet materials is provided with a slope portion facing in the stacking direction of the sheet materials and in a direction of the inside of the bag portion at a position further on an outside of the bag portion than a position at which the welding bead portion is formed.

摘要： This air pump device is provided with: an electric pump unit including a pump mechanism and a motor; a case; and a vibration-proof member. The pump mechanism and the motor are arranged side by side in the axial direction of the motor. The pump mechanism has an inlet and an outlet at an end in the axial direction on the opposite side of the motor. The case has a first wall and a second wall which are located on opposite sides in the axial direction of the motor and which face the electric pump unit. The vibration-proof member is provided with: a first axial vibration-proof unit interposed between the electric pump unit and the first wall; and a second axial vibration-proof unit interposed between the electric pump unit and the second wall. The first axial vibration-proof unit covers the inlet.
