PROBLEM TO BE SOLVED: To securely fix a filter to a body to unfailingly capture foreign objects and achieve improvement of the assemblability in an in-tank valve.SOLUTION: A driving unit 18 forming an in-tank valve 10 includes a housing 30 having a valve mechanism 34 therein. First communication holes 40 which allow a second passage 44 and a tank 12 to communicate with each other are formed on an outer peripheral surface of the housing 30. A cylindrical collar 58 and a filter 36 are provided at the outer periphery side of the first communication holes 40. The filter 36 is made of a metal material and securely fixed to an inner peripheral surface of the collar 58 by welding. The collar 58 is securely fixed to the outer peripheral surface of the housing 30 by welding.SELECTED DRAWING: Figure 3 【課題】インタンクバルブにおいて、ボディに対してフィルタを強固に固定して異物を確実に捕捉すると共に組付性の向上を図る。【解決手段】インタンクバルブ１０を構成する駆動ユニット１８は、内部に弁機構３４を有したハウジング３０を備え、前記ハウジング３０の外周面には第２流路４４とタンク１２内とを連通する複数の第１連通孔４０が形成されると共に、前記第１連通孔４０の外周側には、円筒状のカラー５８と共にフィルタ３６が設けられる。フィルタ３６は、金属製材料から形成されカラー５８の内周面に溶接によって強固に固定されると共に、前記カラー５８が、前記ハウジング３０の外周面に対して溶接によって強固に固定される。【選択図】図３
