<P>PROBLEM TO BE SOLVED: To provide a PCV valve device capable of rapidly discovering any abnormality of the PCV valve device, and enhancing the flexibility of the layout of a PCV piping. <P>SOLUTION: The PCV valve device 100 includes a PCV valve body 1 and a cover member 2. The PCV valve body 1 includes a connection part 13 to be inserted in the PCV pipe 3, and a projecting part 12 which is projected outwardly from an outer circumferential surface of the connection part 13, and fixed to a cylinder head cover CH with bolts B. The cover member 2 includes a fitting part 21 having an insertion hole 21a in which the connection part 13 is inserted, and arranged on the projecting part 12 side from the PCV pipe 3, and a covering part 22 for covering the bolts B. The cover member 2 is constituted so that the fitting part 21 may extrude the PCV pipe 3 from the connection part 13 when the covering part 22 is moved along the connection part 13 to the position where the bolts B can be detached. <P>COPYRIGHT: (C)2013,JPO&INPIT |
