Rotating shaft 13 for rotating the core S of the paper roll body P
has the following structure.

The shaft main body 14 has a large diameter part 15 that is slightly wider than the left end when viewed from the front, and a straight pipe part 17 is formed on the right side of the large diameter part 15 through a diameter-reduced taper step part 16. The brush portion 18 is installed.

For example, a plurality of cut portions 19 are formed on the left end surface of the large diameter portion 15 as a mechanism capable of driving the rotation shaft 13 for rotating the core S of the paper roll body P. For example, two protruding shafts 20 protruding from the drive connecting portion 8 are meshed and engaged with each other at 19 . On the other hand, the right end of the straight pipe section 17 is connected to the support shaft section 21.
is inserted through a hole in the right arm portion 4 and fixed by screwing, so that it moves integrally with the rotating shaft 13.

Generally, the left arm parts 3 and 4 are integrally formed on both left and right ends of the back plate part 2 fixed to the wall so as to protrude forward, but in the present invention, the structure is further improved. Therefore, the configuration of the right arm portion 4 has been devised.

The technical content is that, as shown in Fig. 1, an insertion slit 22 is intentionally formed at the right end of the back plate part 2, and the insertion slit 22 is removably inserted into the slit 22 from the right outside. Do what you get. The right arm portion 4 is
It has an inverted L-shape in plan view, and the right-angled insertion piece 23 is formed into a tapered shape that gradually becomes thinner toward the tip, and the joining surface of the insertion slit 22 is also formed into a matching tapered surface. ing.

Therefore, the insertion piece 23 can be easily removed from the insertion slit 22 of the back plate portion 2 by pulling outward to the right. Both of these 2
If the engaged state of 2 and 23 is strongly held using a known method, for example by coating or stretching a rubber or non-slip resistance material on the joint surface, it will not come off unnecessarily. .

Reference numeral 24 denotes a known cut plate which is supported on the front part of the upper end of the back plate part 2 so as to be freely foldable in the front-rear direction, and whose front end part is slightly curved downward.

For convenience of explanation, the paper roll body is denoted by P and its core body is denoted by S, but they are not shown in the drawings because they are extremely easy to understand.

(Function) In the above configuration, the support shaft portion 2 of the right arm portion 4
