Thus, the paint roller according to the present invention can easily paint the object such as the outer surface or the convex curved surface of the corner refracted in the "? &Quot; form, and the object to be painted can be easily There is an effect that you can select forward and backward (up and down) or left and right in the direction of rotation progression.

1 is an exploded perspective view showing a paint roller according to the present invention.
2 is an enlarged view of the joint roller.
FIGS. 3 and 4 show the arrangement of the first and second rollers when the first pin hole of the joint holder is aligned with the pin hole of the linkage so that the connection pin is fitted.
5 and 6 illustrate the arrangement of the first and second rollers when the second pin hole of the joint holder is aligned with the pin hole of the linkage so that the connection pin is fitted.

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

1 to 4, a paint roller according to the present invention is characterized in that the joint holder 10 is composed of a holder part 11 and a joint part 14, and is perpendicular to the cutout groove 12 of the holder part 11 And the first roller 30 and the second roller 30 are fixed to the first support portion 21 and the second support portion 22 of the support base 20, The first roller 30 and the second roller 40 are disposed at right angles to each other and the outer peripheral surface of the joint portion 14 in which the hollow portion 15 is formed is provided with a first pin hole The first pin hole 16 and the second pin hole 17 are arranged vertically to each other and the hollow portion 15 of the joint portion 14 is connected to the connecting pin 16 and the second pin hole 17, The first pin hole 16 of the joint portion 14 and the second pin hole 17 of the joint portion 14 are inserted into the pin hole 52 formed in the outer peripheral surface of the bending tip 51, And the connecting pin 40 is fitted in a state in which one of them is matched.

The joint holder 10 has a cutout groove 12 formed at the tip end of the holder 11 and a joint portion 14 integrally formed in the holder portion 11 so that the joint portion 14 is integrally formed with the holder portion And a hollow portion 15 is formed in the cylindrical joint portion 14. The first pin hole 16 and the second pin hole 16 are formed on the outer peripheral surface of the joint portion 14, A hole 17 is formed, and the first pin hole 16 and the second pin hole 17 are arranged perpendicular to each other.

The incision groove 12 has a locking projection 13 formed on the inner surface thereof and a locking projection 13 is formed in a V shape so as to conform to the shape of the support base 20.

Thereby, when the bent portion 23 of the support base 20 is fitted into the cutout groove 12 of the holder portion 11, it is not automatically released by the engagement protrusion 13.

The operation of the paint roller according to the present invention will now be described with reference to FIGS. 3 to 6. FIG.
