  • Patent number: 10814916
    Abstract: A vehicle front pillar structure includes a pair of front pillars disposed on both sides of a vehicle to oppose each other. An instrument panel reinforcement to which a steering portion is attached extends between the pair of front pillars (A-pillars). Each of the A-pillar includes an outer reinforcement disposed on a transversely outer side of the vehicle, an A-pillar inner portion disposed on a transversely inner side of the vehicle, and a reinforcing bracket attached to the outer reinforcement and the A-pillar inner portion. The reinforcing bracket is disposed at a position opposing an end portion of the instrument panel reinforcement.

  • Patent number: 6393954
    Abstract: The present invention eases possible rubbing between an upper cutting edge and a work cutting surface of a work cutting apparatus during the elevation of the upper cutting edge to prevent the upper cutting edge from being worn in order to increase its lifetime. In a device for cutting a work by elevating and lowering a movable upper cutting edge 12 relative to a fixed lower cutting edge 13, an upper-cutting-edge, tight-contact avoidance device 10 is provided for widening the clearance between the upper cutting edge 12 and a work cutting surface. The device 10 is comprised of a clearance adjustment mechanism 22 for adjusting the clearance between the upper cutting edge 12 and the lower cutting edge 13, and control device 35 for regulating operation of the clearance adjustment mechanism 22.
