摘要： PROBLEM TO BE SOLVED: To reduce the maximum crush load at the initial stage of load input, by providing, within a closed section of a frame located closer to the outer end of the vehicle than a first bead, a knobbed member which is connected to an inner peripheral surface of the frame and partitions the inside of the frame, and connectingly fixing a bumper thereto. SOLUTION: Within a closed section of a frame 86 which continues to the forward of a first bead 92, two knobbed members 10, 20 are provided in parallel in fore and aft direction for reinforcing the frame 86 so that deformation of the shape of the closed section at collision is prohibited. To a first knobbed member 10 located in the front, a reinforcement 30 for a front bumper is connectingly fixed. On the frame 86, the first bead 92 is formed for reducing the initial maximum bearing force, and the first bead 92 is formed along the entire periphery of the frame 86 including all the angular portions. Therefore, the first bead 92 has made all the angular difficult-to-be-crushed portions easily crushable. This reduces the initial maximum bearing force and reduces the initial load at collision sufficiently.

摘要： PURPOSE: To decrease the initial maximum proof stress in the collision of a vehicle, and improve the mean proof stress, by forming a first bead for improving the means proof stress, in which recessed parts and projecting parts are alternately and repeatedly positioned, and b forming a second bead for decreasing the initial maximum proof stress in the position of the frame car body outer end side from the first bead. CONSTITUTION: When a frame structure is applied to a front frame 86 of an automobile body, beads 90 for improving the mean proof stress are respectively formed on facing flat surfaces 58, 66 of a double hut-type frame. The beads 90 are crushed at the pitch P along the axial direction of the frame 86 in such a range as not to extend to corner parts 72, 74, 80, 82 on both sides of the flat surface parts 58, 66m, and they are formed into a continuous irregular shape so that the recessed parts 90a and the projecting parts 90b extending in the range of the total length of the pitch P may be alternately and repeatedly positioned. Initial maximum proof stress decreasing beads 92 in which a recessed line 92a is formed on one side of the mutually adjacent flat surface 58, 66 forming respective corner parts and a projecting line 92b is formed on the other side, is formed.

摘要： PURPOSE:To provide a steering shaft supporting structure which can surely hold a steering wheel at a prescribed position, when a vehicle collides at the front part. CONSTITUTION:A steering column 3 is fixed with a supporting bracket 14 through the second connecting member 18, and connected with a supporting bracket 14 so as to be separable through the third connecting member 17. Further, the supporting bracket 14 is fixed with a steering supporting member 13, and connected with an inpanel supporting part 12 so as to be separable through both the connecting members 15 and 16. Though, in case of the front part collision, the inpanel supporting part 12 and the supporting bracket 14 are separated by the actions of both the connecting members 15 and 16, and the retreat of the steering column 3 is prevented, a steering wheel 1 can be surely held at a prescribed position, even if the above-described separation does not occur, because the steering column 3 is fixed with the supporting bracket 14 through the second connecting member 18.

摘要： PURPOSE: To make a tibia moment not act on a shin part by preventing that an angle between a foot and the shin part becomes smaller than that at the time of usual traveling caused by a head-on collision, through a simple structure. CONSTITUTION: A front end of a car room 1 is composed of a floor face 2a, a toe board surface 3a rising forward aslant, and a dashpanel 4. A lower mounting piece 5b of a footrest 5 is clamped to the floor face with a mounting bolt 6. The upper part of a body 5a is supported from the toe board surface to the rear with a gap 8 between via an engaging means 7 which is composed of a pin member 7a and a support member 7c, and in an engaged state at usual time, it coms into contact with a peripheral surface of this pin member and supported on the support member, while in time of a collision from the front, the pin member is slidden forward by rear displacement of the support member with the rising deformation of toe board surface, thereby forming an incline 7e relatively shifting the body 5a to the toe board side.

摘要： PROBLEM TO BE SOLVED: To provide an excellent crush characteristic to a body structure especially to which a crush box is installed so as to effectively absorb a collision load by means of a narrow crush space. SOLUTION: Both front end parts 16 of a pair of left and right front side frames 1 are connected together via a cross member 3, and in each of the front end parts 16, an upper end part of a tie-down hook 18 and a radiator bracket 17 are installed respectively so that a highly rigid receiving part 16a is formed. A crush box 2, in which the first and second crush boxes 20, 30 made by press molding of plate material and formed into cup shapes substantially are combined together, is fixed to each of the left and right receiving parts 16a by means of a bolt-nut 35, and then, a bumper reinforcement member 13a is connected to the left and right crush boxes. A clearance in the tip part, of a cylindrical wall part, rigidity of the cylindrical wall part against a crush, and the like are set so that a withstand load peak value of the second crush box is generated in a drop part of the withstand load after a withstand load peak value of the first crush box is generated.
