  • Patent number: 9862423
    Abstract: An object is to provide a vehicle rear portion structure that improves rigidity of a vehicle rear portion. At a wheel house connecting member, both end portions in a vehicle transverse direction of a top surface portion are joined to joining stays that are provided at wheel houses, and lower portions of both end portions in the vehicle transverse direction of a vertical wall portion, that extends toward a vehicle lower side from the top surface portion, are joined to fixing members. Accordingly, vehicle rigidity between the wheel houses, that are connected by the wheel house connecting member at a rear portion of a vehicle, improves.

  • Patent number: 9738323
    Abstract: Falling-in deformation, in which a second quarter pillar deforms so as to fall toward a vehicle vertical direction lower side, is suppressed. Due to twisting input being applied to a vehicle, a second quarter pillar deforms so as to fall toward the vehicle vertical direction lower side. A connecting member, whose lower end portion is joined to a joined region of a wheel house and a lower end portion of a first quarter pillar, receives this falling-in deformation of the second quarter pillar. Accordingly, because the connecting member, whose lower end portion is securely fixed, receives the falling-in deformation of the second quarter pillar, the falling-in deformation of the second quarter pillar is effectively suppressed.

  • Publication number: 20140338492
    Abstract: In an accelerator pedal device, a fitted portion of a pedal is inserted into a groove portion of a fitting portion by sliding the fitted portion, and then the fitted portion and the groove portion are fitted to each other. Furthermore, an engagement hook portion of the fitted portion is engaged with an engagement hole. Still further, an upper wall of the bracket contacts a stopper portion of the mount, so that the engagement hole is restrained from being displaced in a direction away from the fitted portion.

  • Patent number: 7832795
    Abstract: A front side member has: a front frame portion disposed such that a longitudinal direction of the front frame portion runs along a vehicle longitudinal direction; a rear frame portion which is offset toward a vehicle bottom side with respect to the front frame portion at a vehicle rear side of the front frame portion, and which is disposed such that a longitudinal direction of the rear frame portion runs along the vehicle longitudinal direction; and a connecting frame portion connecting a rear end of the front frame portion and a front end of the rear frame portion. A concave portion is formed at a vehicle top-bottom direction intermediate portion of the connecting frame portion. A dash cross member, which is disposed such that a longitudinal direction of the dash cross member runs along a vehicle transverse direction, is provided within the concave portion.
