PROBLEM TO BE SOLVED: To provide a method and apparatus for anodic oxidation treatment of a cylinder member which facilitates management of an anodic oxidation treatment solution.SOLUTION: An anodic oxidation treatment method of a cylinder member comprises the steps of: inserting a nozzle part 55 serving as a cathode into a cylinder member 11 from an opening 12 thereof; bringing a partition part 53 into contact with an edge surface 13a around the opening 12 of the cylinder member 11 to partition the inner surface 11b of the cylinder member 11 with respect to the outer surface 11a; and bringing a contact part 58 serving as an anode into contact with the outer surface 14a of the bottom part 14 of the cylinder member 11; pressing the cylinder member 11 with the contact part 58 and the partition part 53 to cause an anodic oxidation treatment solution L to be discharged from the nozzle part 55 and simultaneously electrifying a current between the contact part 58 and the nozzle part 55.

    【課題】陽極酸化処理液の管理が容易となるシリンダ部材の陽極酸化処理方法および陽極酸化処理装置の提供。【解決手段】シリンダ部材11にその開口12から陰極となるノズル部55を挿入し、シリンダ部材11の開口12の周囲の縁面13aに区画部53を当接させてシリンダ部材11の内表面11bを外表面11aに対して区画して、シリンダ部材11の底部14の外表面14aに陽極となる当接部58を当接させる。当接部58と区画部53とでシリンダ部材11を押圧して、ノズル部55から陽極酸化処理液Lを吐出させるとともに当接部58とノズル部55との間に電流を流す。【選択図】図3
