The surface treatment of rubbing the outer surface of the rubber roller with a liquid absorbing member or the like is performed, and then a primer is applied to coat the fluororesin. On the other hand, in this step, when the rubber layer is rubbed, rubber powder is generated and adheres to the journal portion of the rubber roller, so it is necessary to cover the journal portion in advance.

FIG. 6 shows a part of a conventional surface treatment apparatus used in this step. That is, this apparatus includes a pair of cylindrical mask bodies 1 and 2 and a gear 3 fitted on these mask bodies, and a key 4 is mounted on the mask bodies 1 and 2. On the other hand, a rubber roller 5 requiring surface treatment
Has journal portions 6, 6 at both ends, and these journal portions 6 are provided with key grooves 7 or milling cut surfaces.

In order to mount the rubber roller 5 on the surface treatment apparatus having the above configuration, the key groove 7 of the journal 6 is
The operator positions the key groove 7 and the key 4 so as to face each of the keys 4. Next, the operator inserts one of the journal portions 6 into the mask body 2, and
Is moved to fit the other journal portion 6, whereby the journal portions 6, 6 are covered with the mask bodies 1, 2, and integrated with the mask body to complete the mounting operation.

Thereafter, the gear 3 is driven via a drive mechanism (not shown) to rotate the rubber roller 5 together with the mask bodies 1 and 2. The jig is traversed between the mask bodies 1 and 2 while the liquid absorbing member is pressed against the peripheral surface of the rubber roller 5 by the jig, and the surface of the rubber roller 5 is rubbed.

(Problem to be Solved by the Invention) However, for each rubber roller 5, the operator needs to
And the journal 6 by the operator.
When the rubber roller is inserted into the mask body 2, it takes time and effort to attach the rubber roller, so that the work efficiency in the surface treatment step is low, and it has been difficult to mass-produce the rubber roller.

The present invention has been made to solve such a problem, and an object of the present invention is to provide a rubber roller surface treatment apparatus to which a rubber roller can be easily attached.
