Document Type and Number:
Japanese Patent JP4372989
Kind Code:
B2
Abstract:
A ramp wherein the amount of deformation in the front end edges of guiding parts caused by thermal expansion. The ramp includes at least two guiding parts individually formed for each suspension arm and made of a polymeric material having a small friction coefficient for guiding the suspension arm by sliding into a accommodation zone, and a guide supporting member made of a material having a thermal expansion coefficient smaller than that of the polymeric material of the guiding part for supporting each guiding part at a predetermined position. The guide supporting member has guide support holes which are located in zones to be contacted with the associated guiding parts, are not contacted with associated recording disks, and are engaged with the associated guiding parts at such positions that distances to the front end edges of the guiding parts become shortest. Each of the guiding parts has a projection. When the projection is engaged in the associated guide support hole, the guiding part guides the suspension arm at a suitable position.
