发明名称 VISCOUS FLUID SEALING DAMPER AND MANUFACTURING METHOD THEREFOR
摘要 PROBLEM TO BE SOLVED: To solve a problem in a conventional viscous fluid sealing damper preventing vibration of an on-vehicle disc player and supporting it wherein a gate cut part generated when molding a shaft body remains as a projection and protrudes to the outside to damage a thin-walled flexible part of the other damper when the dampers are packed in a box, when the mounting shaft body is integrally molded with a stirring part and the flexible part made of a soft resin material of a damper main body using a hard resin material. SOLUTION: In this viscous fluid sealing damper 16, the shaft body 20 is integrally molded with the stirring part 28 and the flexible part 30 made of the soft resin material using the hard resin material while it is inserted into a insertion hole 44. At this time, a recessed part 58 having a dimension in the radial direction of 0.5 mm or more and a depth of 0.5 mm or more in the axial direction is provided on a bottom face of the shaft body 20.
