The present invention provides a splinter shield for a vacuum pump, capable of reducing costs of the splinter shield by obtaining a single sheet of splinter shield having a required strength, in which fastening strength to a fixing groove is enhanced to prevent the splinter shield from bending toward the inside of a pump and coming into contact with equipment inside the pump when air rushes into the pump through an inlet port and to prevent the splinter shield from falling. Furthermore, attachment and removal of the splinter shield with respect to the inlet port are facilitated. The present invention is a splinter shield for a vacuum pump in which a rim formed in a circumferential edge portion of the splinter shield is inserted into a fixing groove that is provided in a concave manner in an inner circumferential portion of an inlet port, and the splinter shield is provided in a tensioned manner to the inlet port by pushing a retaining ring into the fixing groove, wherein locking parts that are locked into the retaining ring at a plurality of sections in the rim are provided in a standing manner at substantially right angles to the rim. |
