Abstract: A component for an electronic apparatus has an insulating member that has a plurality of through holes in parallel in which the lead wires are inserted and a shield cover in which an insulating member insertion hole where the insulating member is inserted is formed that cut offs an electrical noise. The insulating member is formed in an integrated shape where parts of adjoining cylindrical parts in which the through holes are formed overlapping mutually when seen along an axial direction of the through hole. The insulating member insertion hole becomes a single hole formed identical to an outer shape of the insulating member when seen along the axial direction of the through hole.

Abstract: An injector having an injector body, in which a housing opening and a communication hale are provided, includes a supporting member fixed to an actuator, which includes a lead-wire supporting portion that supports ends of lead wires and a plate portion formed integrally with the lead-wire supporting portion. A thickness of the plate portion is smaller than that of the lead-wire supporting portion, and multiple trench portions are provided on a surface of the plate portion so that the plate portion can be easily bent. While the supporting member passes through the housing opening, the lead wires straight move. After an end portion of the supporting member contacts the communication hole, external force is applied to the end portion to bend the plate portion, and thereby the lead wires are bent while moving in the communication hole.
