Abstract:
1. A mechanical chassis apparatus including a non-contact reading mechanism for a disc recording medium and a vibration preventing damper attached on a chassis member supported in a floating condition through the vibration preventing damper within a casing, comprising: the vibration preventing damper having a damper housing made of a resin material, provided with a holder portion in a form of a container opened at one end for inserting a support shaft provided in the casing and an elastic wall portion for reducing floating movement of the support shaft due to elastic deformation in three-dimensional directions, and the chassis member having a resin hole edge covering portion for covering a hole edge of a through hole formed in the chassis member with both front and rear surfaces of the chassis member, wherein the opening side end portion of the damper housing is fixed to said resin hole edge covering portion on one side surface of the chassis member and a lid member made of a resin material is fixed to said resin hole edge covering portion on the other side surface of the chassis member, so that said resin hole edge covering portion at the chassis member is forming a portion of the vibration preventing damper, and said vibration preventing damper is formed integrally with said chassis member without using mechanical fasteners.
