Abstract
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.
