  • Patent number: 9457769
    Abstract: A fin part (21e) is provided on a side opposite to a wiping surface side of a rubber holder (21) to press a blade rubber (22) toward the wiping surface side by receiving a wind (W) flowing along a moving car, and covering parts (23) protrude from both lengthwise ends of the blade rubber (22) toward the wiping surface side so as to partially cover lateral parts of the blade rubber (22). Owing to the fin part (21e), liftoff of a wiper blade (20) can be prevented. A wind (W) flowing from the front side to the rear side at an end part of a swing center side of the blade rubber (22) can be rectified by the covering part (23), and the wind (W) can flow along the rear side of the wiper blade (20) in the length direction of the wiper blade (20).

  • Patent number: 9239115
    Abstract: A gland packing provided in a fluid apparatus such as a pump and compressed in an axial direction so as to prevent penetration leakage of a fluid is provided. The gland packing has a packing base material 11 of a predetermined length including a band-like flat braid 12 braided by moving a plurality of yarns 13 along one track K. The band-like packing base material 11 is shaped into a ring by abutting longitudinal ends 12a and 12b of the packing base material 11 so that a width direction thereof is parallel with a packing axial direction, and is then compressed in the axial direction, whereby the packing base material 11 is overlappedly folded in a packing axial direction, with a longitudinal direction of the packing base material 11 as a direction of folding lines 14.

  • Patent number: 9003598
    Abstract: An interval between an inner face 31c1 of a back wall 31c in a rubber holder 31 and a blade rubber 32 is formed so as to become gradually expanded with respect to an interval between an inner face 31b1 of a front wall 31b and the blade rubber 32 as being directed toward a center portion from both longitudinal-directional end portions of the rubber holder 31. Also, an interval between an inner face of each back wall in a pair of covers coupled to the both longitudinal-directional end portions of the rubber holder 31 and the blade rubber is formed so as to become gradually expanded with respect to an interval between the inner face of the front wall and the blade rubber as being directed toward the center portion from both longitudinal-directional end portions of the cover. Accordingly, a flow of travel wind during a travel of a vehicle is facilitated between the rubber holder 31 and the blade rubber 32 or between the covers and the blade rubber 32.
