Abstract: A cleaner to conduct dust-removing by jetting air from a dust-removing head 1 to a cleaned face 11 of a work W having the cleaned face 11 of three-dimensional configuration, in which the dust-removing head 1 is provided with a work-corresponding face 1a of three-dimensional offset configuration parted from the three-dimensional configuration of the cleaned face 11 for a small dimension G.

Abstract: A cleaner head having a discharging slit 6 on the center and sucking slits 7 on left and right on a corresponding wall portion 15 facing a dust-removed face 10, and, outer extended lines L7 of the pair of sucking slits 7 are inclined as to mutually come close and intersect as departed from the corresponding wall portion 15.

Abstract: In a cleaner apparatus for steel plate provided with a brush roll 1 driven to rotate to remove foreign matter D from a surface Wa of a steel plate W to be conveyed, a magnet bar 3 to attract iron powder d among the foreign matter D stuck to the brush roll 1 by magnetic force, a wiping cloth 5 disposed between the brush roll 1 and the magnet bar 3 to remove the foreign matter D attracted by the magnet bar 3; the wiping cloth 5 of belt shape is disposed parallel to an axis L1 of the brush roll 1.

Abstract: An airbag (10) has a vent hole (18) in one side end portion. One end of a third base fabric (20) is sewn to the airbag (10) through a first sewn portion (23) that closes the vent hole (18), and the other end of the third base fabric 20 is sewn to the other side end portion of the airbag (10) through a second sewn portion (24). The first sewn portion (23) has weaker binding force by sewing than the second sewn portion (24) so that the first sewn portion (23) is separated to open the vent hole (18) when tension force is applied from the third base fabric (20) to the first and second sewn portions (23) and (24).

Abstract: Intended is to always provide effective impact reduction by releasing gas at a timing of pushing into airbag. An airbag (10) has a vent hole (18) in one side end portion. One end of a third base fabric (20) is sewn to the airbag (10) through a first sewn portion (23) that closes the vent hole (18), and the other end of the third base fabric 20 is sewn to the other side end portion of the airbag (10) through a second sewn portion (24).

Abstract: To enhance an occupant restraining force of an airbag, and to improve a protective function for an occupant of an airbag device by discharging gas without fail regardless of a position of the occupant, an airbag (10) is divided into a first chamber (10A) on an inflator (2) side and a second chamber (10B) on an occupant side by a partition wall (11), and the first chamber (10A) includes an opening (23) to which a discharge-state switching member (30) having vent holes to discharge the gas in the airbag (10) and being switchable between the discharge/non-discharge states is attached. The discharge-state switching member (30) is coupled to the partition wall (11) by a tether belt (40), so that the tether belt (40) applies tension to close the vent holes when the airbag (10) inflates, and when the airbag (10) receives an occupant, releases the tension depending on the position of the receipt, and opens the vent holes.
