Abstract

The present invention relates to a driving device of an electric folding type side view mirror for a vehicle, comprising: an upper case ( 30 ) in which a motor seating part is formed; an electric motor ( 40 ), installed inside the upper case ( 30 ), for generating rotation power; a worm gear ( 11 ) installed at a rotational axis ( 14 ) of the electric motor ( 40 ); a worm wheel gear ( 12 ), connected to the worm gear ( 11 ), for transferring the rotation power; a lower case ( 20 ) formed with fixing means ( 21, 22 ); a cap spring ( 14 ) fixed to the lower case ( 20 ) by the fixing means ( 21, 22 ) and a cap ( 13 ), mounted at a top of the cap spring ( 14 ), for receiving a lower end of the rotational axis ( 14 ).

First claim

The invention claimed is:

1. A driving device of an electric folding type side view mirror for a vehicle, comprising:
an upper case in which a motor seating part is formed;
an electric motor, installed inside the upper case, for generating rotation power;
a worm gear installed at a rotational axis of the electric motor;
a worm wheel gear, connected to the worm gear, for transferring the rotation power; and
a lower case formed with a fixing means;
a cap spring fixed to the lower case by the fixing means;

the fixing means for fixing the cap spring in the lower case is formed with a boss, the boss having a saw-toothed outer peripheral surface onto which the cap spring is seated; and
a cap is mounted at a top of the cap spring for receiving a lower end of the rotational axis.

2. The driving device of an electric folding type side view mirror for a vehicle according to claim 1 , wherein
the lower end of the rotational axis of the electric motor extends beyond the upper case such that it can apply a pressing action to the cap and the cap spring.

3. The driving device of an electric folding type side view mirror for a vehicle according to claim 1 , wherein
a center section of the top surface of the cap is formed with a hole for receiving the lower end of the rotational axis of the electric motor.

4. The driving device of an electric folding type side view mirror for a vehicle according to claim 1 , wherein
a plurality of bending sections for fixing the cap spring are disposed at the cap while forming a circle.

5. A driving device of an electric folding type side view mirror for a vehicle, comprising:
an upper case in which a motor seating part is formed;
an electric motor, installed inside the upper case, for generating rotation power;
a worm gear installed at a rotational axis of the electric motor;

a worm wheel gear, connected to the worm gear, for transferring the rotation power; and
a lower case formed with a fixing means;
a cap spring fixed to the lower case by the fixing means;

the fixing means for fixing the cap spring in the lower case is formed with a rib, the rib being formed by two lines in order to insert the cap spring into the rib; and
a cap is mounted at a top of the cap spring for receiving a lower end of the rotational axis.
