Abstract: A double-wishbone type of suspension device for a vehicle comprises a forked-shaped upper arm, a forked-shaped lower arm, and a connecting rod which connects a front-side arm portion of the upper arm and a rear-side arm portion of the lower arm, wherein the connecting rod comprises an upper rod which is rotatably connected to the upper arm, a lower rod which is rotatably connected to said lower arm, and a resilient bush which connects the upper rod and the lower rod in an expandable manner in an axial direction.

Abstract: A subframe structure of a front suspension that leads a subframe and a vehicle driving apparatus to the lower side after separation of a rear portion of the subframe due to a frontal collision without increasing weight and parts. A subframe structure of the front suspension provides a subframe that supports a vehicle driving apparatus in a mounting manner, and a rear portion of the subframe is mounted on a lower portion of a vehicle body via a fastening member. Fastening between the subframe and the fastening member is configured such that the rear portion of the subframe is separated when a collision load to a vehicle rear side is applied to the subframe. A leading guide portion that abuts against the fastening member and leads the subframe to a lower side after separation from the fastening member is integrally formed on the rear portion of the subframe.

Abstract: A vehicle-body front structure includes a tower portion comprising a pole portion which extends substantially vertically and a tower top portion which is positioned at an upper portion of the pole portion and projects from the pole portion longitudinally along a front side frame, constituting attachment portions of an upper arm of a front-wheel suspension. A stabilizer-support pedestal for supporting a stabilizer is provided to be connected to the pole portion and the tower top portion. Thus, the pole portion of the sub frame can be properly reinforced by using the stabilizer-support pedestal, so that the rigidity of the upper portion of the pole portion can be properly increased.

Abstract: A pair of right-and-left extension members which deform and absorb an impact at a vehicle frontal collision, in cooperation with a pair of front side frames, are provided. The extension members are configured to be joined to respective middle portions, in a height direction, of a pair of tower portions of a sub frame at their rear end portions, to project forward, bending outward at a level below the front side frames, and to be comprised of a pair of members having a closed cross section, respectively. The rear end portions of the extension members joined to the tower portions are positioned so that a center line of a longitudinal direction of each of the extension members at the rear end portion is located at an inward position relative to a center line of a standing-vertical direction of each of the tower portions.

Abstract: Front side frames 1 of a vehicle are each vertically connected through a corresponding one of joint members 7 to a cross member 2 configured to support a suspension arm below the front side frame 1. The joint members 7 are each coupled to a back end of a corresponding one of extension frames 4. This allows the front side frames 1 and the cross member 2 to share the load experienced by the extension frames 4 in a frontal collision of the vehicle.

Abstract: This invention relates to a shielding material used as a radiation shield of a container containing radioactive wastes. A radiation shield with an excellent heat-transferring property is fabricated from composite particles (A) obtained by coating core particles (a) of radiation-shielding property with a metal (b) of high thermal conductivity. Composite particles are formed into a certain shape of radiation shield by hot-press forming or other forming or packed into the internal space of radioactive waste container or the shield container cavity to compose a radiation shield.
