摘要： PROBLEM TO BE SOLVED: To mold electrical wiring in a timing belt cover without making the timing belt cover large-sized by molding metallic wire material of circular cross section as the electrical wiring inside the timing belt cover made of resin. SOLUTION: A timing cover 11 has a connection part, and metallic wire material 13 of circular cross section is molded as electrical wiring. The metallic wire material 13, the electric wiring, is molded between a first connector part 12a and a second connector part 12b in the timing belt cover 11. The sectional diameter of a wiring part that is not rolled is smaller than the width of an end part and larger than the thickness of the end part, so that the timing belt cover 11 does not become large-sized even in case of molding the electrical wiring in the timing belt cover 11. The metallic wire material 13 has circular cross section so as to be high in freedom of bending directionality. The metallic wire material can therefore be molded in an optional direction in the timing belt cover 11 so as to be able to supply a necessary current.

摘要： PURPOSE: To make stress to be applied to a resin to the minimum extent or zero when a housing is resin-caulked, to prevent creep from being generated, and to decrease the number of parts and assembling man-hours, by covering at least the outer peripheral surface of a flange part of a fuel distributing pipe with a metallic plate. CONSTITUTION: A flange part 10a of a resin-made fuel distributing pipe 10 is provided with a metallic plate 11 on the outer peripheral surface, and a housing 12 is caulked and fixed to the resin-made flange part 10a. This metallic plate 11 is constituted of respective two divided parts and each of which is formed into a U shape in section. Therefore, stress to be applied to a resin can be made to the minimum extent or zero, and creep can be prevented from being generated on a resin. It is not necessary for the housing 12 to be fixed to the flange part 10a of the resin-made fuel distributing pipe 10 by means of a fastening member such as a bolt, assembly can be easily performed by only fitting work, and therefore, the number of parts and the assembling man- hours can be decreased.

摘要： PURPOSE: To achieve simplification of mounting of a fuel injection valve to a distributing pipe by completing connection to a fuel injection valve side through a process of connecting the distributing pipe to a housing for housing the fuel injection valve after integrating a lead wire with a solenoid in the distributing pipe. CONSTITUTION: A first passage 14 extending in the longitudinal direction is formed in a main body part 12, and the first passage 14 is communicated with a second passage 15 formed in a suspending part 13. A solenoid 16 is wound on the suspending part 13 and inserted into an upper opening of an aluminum- made housing 17. A hole 19 communicated with an intake pipe 18 is formed under the housing 17. A fuel injection valve 20 is arranged in the housing 17, and the hole 19 of the fuel injection valve 20 is opened by excitation of the solenoid 16 with electrification to a pair of lead wires 21 embedded in a distributing pipe 11, and connected to both ends of a solenoid 16. Electric power is supplied to a pair of lead wires 21 by an input connector formed on the end of the main body part 12.
