<P>PROBLEM TO BE SOLVED: To solve a problem of deflection at expansion/contraction motion of a spring used for a suspension, to realize driving and riding comfortability of a vehicle, and to realize extended life by reducing friction in the lateral direction that occurs to a supporting rod. <P>SOLUTION: A spring seat (11), which supports the spring (10) used for the suspension, includes: a pillow ball (11d), which is incorporated at the center of the spring seat (11) of roughly a disk shape and has two flat surfaces (11d1, 11d2) parallel to each other, a ball hole (11d3) penetrating between the two flat surfaces (11d1, 11d2) in the perpendicular direction to each flat surface, and a spherical side (11d4) extended between each circumferential edge of the two flat surfaces (11d1, 11d2); and a spherical inner wall (11e1) formed inside the spring seat (11) to receive the spherical side (11d4) of the pillow ball (11d) rollably. <P>COPYRIGHT: (C)2012,JPO&INPIT |
