摘要：
High-precision, low-cost molding of dynamic pressure generating grooves is made possible.An ultrasonic generating device 20 is connected to an injection mold 10. The dynamic pressure generating grooves are molded by means of radial dynamic pressure generating groove forming parts 16 and a thrust dynamic pressure generating groove forming part 17 provided in the injection mold 10, with ultrasonic vibration generated by the ultrasonic generating device 20 being applied to the injection mold 10 during the injection molding.
