Patent number: 5549350Abstract: A rear underbody which forms a rear-under section of a vehicle body is provided with a pair of rear floor side members disposed along a longitudinal direction of the vehicle body in respective vicinities of both end portions of the rear underbody in a transverse direction of the vehicle body. The pair of rear floor side members each forms an enclosed cross-sectional configuration which extends in the longitudinal direction of the vehicle body. A cross member which extends substantially straight in the transverse direction of the vehicle body is disposed apart from and under a rear floor pan between the pair of rear floor side members at respective substantially central portions of a pair of rear wheel house inners. Both end portions, in the transverse direction of the vehicle body, of the cross member are respectively welded to an inner surface of the inside wall portion, in the transverse direction of the vehicle body, of the rear floor side member.Type: GrantFiled: April 3, 1995Date of Patent: August 27, 1996Assignee: Toyota Jidosha Kabushiki KaishaInventors: Akira Akiyama, Michio Arakawa, Hisashi Ogawa, Hartmut M.

Patent number: 5443280Abstract: An intermediate portion of a cylindrical suspension member collar extending in a longitudinal direction of a vehicle body is welded to an end portion of a suspension member in a transverse direction of the vehicle body. Both longitudinal-direction end portions of the suspension member collar are reduced in diameter in comparison with the intermediate portion thereof. The suspension member collar is disposed between respective inner cylinder portions of a pair of mounts so as to be coaxial with the inner cylinder portions. A shaft member is inserted into the inner cylinder portion of the mount and the suspension member collar, and a rubber bushing is disposed between an outer cylinder portion of the mount and the inner cylinder portion thereof, so that the outer cylinder portion and the inner cylinder portion can rotate relatively to each other. This makes it possible to prevent the rotation of the side member about an axial center thereof.Type: GrantFiled: November 26, 1993Date of Patent: August 22, 1995Assignee: Toyota Jidosha Kabushiki KaishaInventors: Masakiyo Kawaguchi, Keiichi Yoneda, Naoto Hirasaka, Akira Akiyama
