An electric noise suppressor for a direct current motor comprises a grommet, a choke coil and an electrical terminal. The grommet has an accommodating portion for accommodating the choke coil, an engaging portion for being engaged with a brush holding board of the motor, and a holding portion for holding the terminal. A pair of supporting portions for supporting a pigtail connector are formed to symmetrically protrude from an upper peripheral portion of the accommodating portion. Therefore, the terminal and the pigtail connector are disposed outside the accommodating portion of the grommet, thereby enabling inductance of the choke coil to increase. Further, the pigtail connector, the choke coil and the terminal are restricted from moving and chattering. As a result, the electrical noise suppressor requires less mounting space and is highly reliable.

In a lead wire guiding structure applied to a motor actuator, a case member holding lead wires, electric connecting portions and the like has a through hole from which the lead wires protrude, and a notch. Further, a cover for covering the case member has a guide wall. The guide wall forms an opening along with the notch of the case member, and simultaneously bends the lead wires protruding from the through hole so that the lead wires are received in the notch of the cover. Accordingly, the lead wires can protrude outside through the opening in a required direction.
