  • Publication number: 20230332633
    Abstract: An outer member, an inner member, and an inside fixing member overlap each other and fastened together by a fastening member. The outer member is made of fiber reinforced resin, and fibers contained in the fiber reinforced resin-made outer member are arranged in a direction crossing the above-described overlapping direction. A bolt of the fastening member comprises a conical (truncated cone-shaped) middle portion which is poisoned between a head portion and a shaft portion. In a case where the outer member and the bolt are offset from each other in a radial direction of a through hole of the outer member, the conical middle portion partially contacts an edge portion of the through hole and compress a contacted portion of the outer member in the overlapping direction.

  • Patent number: 11542879
    Abstract: An EGR device for a vehicle includes a valve driver, a pressure comparison unit, a freeze determination unit, and an EGR controller. The valve driver drives an EGR valve to open, when fuel cut has been continued for a predetermined time in a state where an engine speed of a vehicle's engine is equal to or higher than a predetermined rotational speed. The pressure comparison unit compares a pre-driving pressure of an engine's intake pipe with a post-driving pressure of the intake pipe. The freeze determination unit sets a flag indicating that the EGR valve is frozen when a difference between the pre-driving pressure and the post-driving pressure is less than a predetermined value and an external temperature is less than a threshold. When the flag has been set, the EGR controller sets a control state of the EGR valve to a closed state and stops EGR control.
