Abstract
The present invention provides an apparatus for plating pretreatment of a cylinder block that includes an electrode performing a plating pretreatment of the cylinder inner wall surface. A gap flow channel communicates with an in-electrode flow channel at a position closest to a seal jig, the gap flow channel being adapted to introduce a treatment liquid to the cylinder inner wall surface, the in-electrode flow channel being adapted to receive the treatment liquid having passed through a communicating hole. The present invention is provided a method for pretreating before plating a cylinder block including disposing an electrode to face the cylinder inner wall surface so as to form a gap flow channel, and introducing a treatment liquid to the gap flow channel thereby flowing through the treatment liquid toward a seal jig and then into an in-electrode flow channel through a communicating hole.
