  • Patent number: 7008195
    Abstract: A spring locating body (36) is a substantially annular shape formed with an annular recess (38) and a radially inner circular hole (40) that extends through the spring locating body (36). The spring locating body (36) is a substantially rigid plastically deformable material such as nylon. Extending radially outwardly from the spring locating body (36) are four limbs (42). The limbs (42) are equally spaced around the spring locating body (36) at intervals of 90°. Extending away from the rear surfaces of each limb (42) is a deformable rib (44). Each rib (44) extends across the respective limbs (42) in an arc about the central axis (46) of the spring locating body (36). The ribs (44) have a triangular cross-section the apex of which is distant from the limb (42). Alternatively, the ribs (44) can be in the form of a plurality of cone shaped nibs extending in a direction away from the surface of the respective limbs (42).
