Abstract: <P>PROBLEM TO BE SOLVED: To provide a clip member for a fuel feed device capable of reducing work manhours, achieving high strength to force acting in an axial direction of an injector, and reducing move of the injector without causing the clip member to be enlarged.  <P>SOLUTION: End parts of side plate parts 41 and 42 on the side of a second arm part 50 are formed as support surfaces 41a and 42a to support the injector. Since the plate thickness direction of the side plate parts 41 and 42 is roughly perpendicular to the axis of the injector, the plate thickness direction of the side plate parts 41 and 42 is roughly perpendicular to force acting from the injector to the support surfaces 41a and 42a. Even in the case of improving strength of the side plate parts 41 and 42 to the force acting from the injector to the support surfaces 41a and 42a, therefore, length of the side plate parts 41 and 42 in the axial direction of the injector can be extended without increasing plate thickness of the side plate parts 41 and 42. The clip member 30 is thus prevented from being enlarged in accordance with increase in the plate thickness.  <P>COPYRIGHT: (C)2004,JPO
