IPC: B60G7/00
Filed: 2002-04-10
Abstract: <P>PROBLEM TO BE SOLVED: To prevent rigidity of a link from being reduced by inhibiting a deformation of a curved part caused by an axis load even in the case where a specific area between both ends of the link is curved.  <P>SOLUTION: In the case where a curved part 3 is set such that a specific area between both ends pivoting connection part 2 of a road part 1 is not interfered with the other parts, a bending moment acts such that an axial load acting on a rod part 1 varies a curvature of the curved position 3. Therefore, in order to enhance bending rigidity of the curved part 3, the cross section is made to an I shape cross section in which both sides 3a at both sides of a plane including a circular line 6 are outwardly recessed and the length of the inner side 3c is made longer than that of the outer side 3b of the I shape cross section. The cross section shape of the straight parts 4, 5 is made to a lengthy rectangular cross section shape in a direction along the plane including the circular line 6. The I shape cross section of the curved part 3 can enhance bending moment rigidity of the curved part 3 without causing an increase of weight. A bending deformation of the curved part 3 when the axial load is applied to the rod part 1 is inhibited and it can be avoided that the link rigidity against the tensile load and the compression load of the link member is reduced.  <P>COPYRIGHT: (C)2004,JPO
