However, the armature shaft provided in the window lift motor configured as described above has a problem in that the manufacturing cost increases due to the increase in the number of parts due to additional assembly of a separate washer or rubber damper in front of the shaft in order to perfectly compensate for clearance.

In addition, a separate washer or rubber damper must be additionally assembled in front of the shaft, thereby complicating the process step.

Therefore, the present invention has been invented to solve the above problems, and since the full length can be directly adjusted through the rolling method around the armature shaft front outer side, it is possible to make the clearance correction airtight, thereby reducing the manufacturing cost. The aim is to provide an armature shaft for motor play compensation.

The overall length of the armature can be adjusted by rolling around the front of the armature shaft, simplifying the process step by eliminating the need for additional washers or rubber dampers.

The present invention for achieving the above object, the armature shaft disposed along the longitudinal direction of the motor housing, the armature wound on the outer peripheral surface of the armature shaft, and is attached to the inner peripheral surface of the motor housing in a state spaced apart from the armature A magnet, a commutator fixed to an outer circumferential surface of the armature shaft to supply electricity of a battery delivered through a brush to a winding wound on the armature, a gear case opposed to the motor housing and coupled through a fastening means, and the armature In the armature shaft provided in the window lift motor comprising a worm formed on the outer circumferential surface of the shaft and a worm wheel for transmitting the rotational force of the armature shaft transmitted through the worm to the output shaft, the front circumference of the armature shaft, The flax at the same time as the compression by the lower motion It characterized by a rolling portion configured to be formed by rotation of the shaft.

The present invention will be further clarified through the following preferred embodiments described with reference to the accompanying drawings. Hereinafter, the present invention will be described in detail to enable those skilled in the art to easily understand and reproduce the present invention.

As shown in Figs. 1 to 3, the armature shaft for motor play correction according to the present invention thus comprises an armature shaft 11 arranged along the longitudinal direction of the motor housing 1, and the armature shaft 11 An armature 111 wound around an outer circumferential surface, a magnet 12 attached to an inner circumferential surface of the motor housing 1 while being spaced apart from the armature 111, and fixed to an outer circumferential surface of the armature shaft 11 through a brush. A commutator 112 for supplying electricity of the battery to the winding wound on the armature 111, a gear case 2 opposed to the motor housing 1, and coupled through a fastening means 21, and the It includes a worm 113 formed on the outer circumferential surface of the armature shaft, and a worm wheel 114 for transmitting the rotational force of the armature shaft 11 transmitted through the worm 113 to the output shaft 22.

The armature shaft 11 is rotated when the motor rotates forward or reverse by driving the motor.

That is, as the worm 113 engaged with the worm wheel 114 formed on the outer circumferential surface of the armature shaft 11 is rotated, the side window provided in the vehicle can move.

In addition, the front circumference of the armature shaft is characterized in that it consists of a rolling portion (3) formed by the rotation of the armature shaft 11 simultaneously with the compression by the up, down movement of the rolling machine (4).

In particular, the rolling part 3 is provided with a stepped jaw 31 provided on both sides and a circular rod 32 formed between the stepped jaw 31.

That is, as the rolling part 3 is formed by the compression of the rolling machine 4 simultaneously with the rotation of the armature shaft 11, the full length of the armature shaft 11 can be directly adjusted.

Therefore, it is possible to prevent vibrations and the like caused by the rotation of the armature shaft 11 and to ensure perfect clearance correction.
