Abstract

Disclosed is a structure (14) in which two structural members (18, 20) that each include thick portion and that have a plurality of bolt holes (26, 28, 30, 32), wherein the two structural members are overlapped at the thick portion and fastened together with bolts (42) at the plurality of bolt holes. In this structure, a certain amount of play is provided respectively for the bolts (42) at the bolt holes (26, 28, 30, 32) so that a shear force resulting from an external force applied to the structure (14) acting on the bolts (42) is even after at least one of the two structural members is deformed by the external force.

Description

technical field

[0001] The present invention relates to a structure having a higher strength bolt fastening at which two structural members are screwed together. Background technique

[0002] Japanese Patent No. 3936799 describes a beam structure for an automobile body or other body in which the beam spans between the side frames of the vehicle and the output side of the transmission is supported on the body. In this structure, each end of the beam is attached to the side frame with three bolts respectively passing through elongated bolt holes that are not aligned in line. In the event of a vehicle crash, the structure prevents the transmission and engine from protruding toward the floor, yet allows the transmission and engine to be displaced toward the rear. Furthermore, Japanese Patent Application Publication No. 2005-212503 (JP-A-2005-212503) describes an automobile body lower structure. In the structure, the floor cross member extends on the floor of the vehicle body i...
