Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings.

Figure 3 is an exploded perspective view of a vehicle auxiliary handle having a bearing mounting structure according to a preferred embodiment of the present invention, Figure 4 is a cross-sectional view of FIG.

As shown in the drawing, the auxiliary handle of the present invention is hinged in an annular shape so that the auxiliary handle is fastened to the steering handle, and the other end has a predetermined depth in the upper surface of the through hole 116 and the extended portion formed to extend the screw. A connection bracket 110 having a recessed seating part 112 and a protrusion 114 formed on at least one seating part 112 thereof; It has a screw thread 124 on the inner surface of the hollow portion to be screwed with the bolt 102 is inserted from the downward through the through hole 116, and is coupled to the protrusion 114 to be fixed to the protrusion 114 A fixing rod 120 having a locking groove 122 formed at a lower surface thereof and having a protrusion 126 having a predetermined diameter at an upper end thereof; A bearing 130 having a press-fitting hole in the center thereof so that the protrusion 126 of the fixing rod 120 is fitted; Lower handle 140 having a concave portion 144 has a locking jaw 142 is formed so that the bearing 130 is seated, when the lower handle 140 is combined with the lower handle 140 is pressed downward to be in close contact with the upper surface of the bearing 130 Protrusion 152 is formed is composed of a handle consisting of an upper handle 150 to prevent the bearing 130 from flowing.

The protrusion 114 is configured to prevent the fixing rod 120 is rotated together in accordance with the rotation of the bolt 102 when screwing.

The concave portion 144 is configured to a suitable diameter so that the bearing 130 is seated on the locking jaw 142, the pressing protrusion 152 is the concave portion 144 in the state in which the bearing 130 is seated It is inserted into the bearing 130 is in close contact with the upper surface is configured.

Referring to the effect of the present invention configured as described above are as follows.

First, the annular portion is mounted on the steering wheel (not shown), and then the bolt 102 is inserted into the fixing rod 120 by inserting the bolt 102 from the bottom of the through hole 116 formed in the extension portion of the connection bracket 110. . At this time, the one or more protrusions 114 formed on the seating part 112 are embedded in the locking grooves 122 formed on the bottom surface of the fixing rod 120 so that the fixing rod 120 is fixed even though the bolt 102 is rotated. Because it maintains the state it is possible to fasten the fixing rod 120 and the bolt 102 easily.
