  The pair of left and right roll paper support arms in Patent Document 1 is such that the upper part of each arm is slidably supported with respect to the fixed base, and each roll is extended in the left-right direction so that the roll paper support part is made of the roll paper. After inserting the air core on both sides, holding the roll paper with one hand, the other hand supports the roll paper in a slidable manner by narrowing the facing distance between the support parts. There is a serious problem that it cannot be executed with one-handed operation and is extremely inconvenient.

  In addition, on the left and right sides or one side of the roll paper holder in the above-described conventional example, a space for inserting the air core of the roll paper into the support arm and a space for removing the empty core tube from the support arm are necessary. There is also a fundamental problem that the roll paper holder of Patent Document 1 cannot be installed in a narrow place where a void cannot be taken, for example, in a wall recess.

  Furthermore, the left and right roll paper support arms in Patent Document 1 are slender as described above, and because the upper part of the arm far from the roll paper suspension part is slidably supported by a cantilever, so that it is mechanically weak, In particular, the longer the gap between the left and right arms is shortened, the shorter the support part is, the basic principle is that excessive stress is applied to the support part during roll paper replacement or during use due to the lever principle, resulting in damage. There is a serious problem.

  Next, the left and right support arms in Patent Documents 2 and 3 are also elongated, and the upper part is pivotally supported by the fixed base so that the left and right support arms can be tilted left and right with one hand against its own weight. While holding up the roll paper with the other finger while spreading upward, insert the opposite support part at the bottom of each arm into the air core of the roll paper with the other finger one by one, and then by the weight of this roll paper and the left and right arms The interval between the support portions is narrowed so that the roll paper can be rotatably supported.

  However, this roll paper support operation cannot be performed with one hand as described above, and it is very inconvenient. On the left and right sides or one side of the roll paper holder, the support portion under the arm is inserted into the air core of the roll paper. Since there is a need for a space for removing the empty core tube from the space and the support arm, it is fundamental that this conventional roll paper holder cannot be installed in a narrow space where this space cannot be taken, for example, in a wall recess. There are many serious problems.

  The roll paper holders of Patent Documents 2 and 3 are cantilevered so that the upper part of each elongated support arm far from the roll paper suspension support portion can be pivoted by a hinge. However, there is a big problem that the swing part is easy to swing like a swing with the hinge part as a fulcrum, and there is a risk that the support part may come out of the roll paper core or the core tube and fall the roll paper, and it is far away from the roll paper support part. In addition, the pivotal part of the long and narrow arm is subject to excessive stress during roll paper replacement or use due to the principle of lever, and the pivotal part is damaged and becomes unusable. There are some problems.

  Furthermore, apart from the above-mentioned patent documents, as a conventional roll paper holder made by simply bending a round bar material, a long and narrow round bar material such as a stainless steel bar is bent into a horizontally long U shape as shown in FIG. A roll paper holder main body 15 is formed, and its upper bar 16 is attached and fixed to a toilet wall surface or the like by a fixture 17, and is supported on an elongated holder lower bar 18 to be rotatable through the entire width of the air core 7A of the roll paper 7 or the core tube 7B. In some cases, a roll paper holder in which the roll paper 5 is prevented from coming off by the upward protrusion 19 at the tip of the holder has also appeared in Japan.

  Although this conventional roll paper holder is a simple roll paper holder with no moving parts, the holder lower rod 18 is supported by being suspended from the holder lower rod 18 through the entire width of the air core 7A of the roll paper or the core tube 7B. 18 is a roll paper set space for inserting the air core 7A of the roll paper 7 or the core tube 7B and a space for removing the empty core tube from the support arm, the sum of the total width of the roll paper and the diameter of the upward projection 19 Since a space larger than the size is required on the right side of the protrusion 19, this conventional roll paper holder cannot be installed in a narrow space where this space cannot be taken, for example, in a wall recess or near the side wall. There are many serious problems.

  Further, in the conventional roll paper holder as shown in FIG. 20 described above, the roll paper air core 7A or the core tube 7B is attached to the holder lower bar 18 through the upward protrusion 19 for preventing the protrusion from protruding at the tip of the holder lower bar 18. Since the roll paper having the air core 7A or the core tube 7B having a diameter equal to or smaller than the sum of the diameter of the lower bar 18 and the height of the upward protrusion 19 is passed through the lower bar 18, the roll paper is set. There is an essential and big problem that it cannot be used.

  This invention strengthens the pivotal support portion of the fixed shaft and the roll paper support shaft by the fitting pivotal support structure between the cylindrical parts, so it is smart and robust, and can be installed in the wall recess or in one corner of the wall surface, The object is to obtain a roll paper holder made of a bar or tube that can be used with one hand (the tube is also considered as a bar because the tube is a hollow bar).

  The above-described object of the present invention is to construct a roll paper holder that rotatably supports the roll paper by inserting a support shaft on both sides of the roll paper air core. After the twisted elastic body is inserted and inserted into the cylindrical part standing upright at one end of the roll paper support shaft, the fixed shaft and the support shaft are fitted to each other, and the support shafts are made to face each other. In this state, each of the fixing portions in the vicinity of both ends of the elastic body is fixed to the fixed shaft cylinder portion and the support shaft cylinder portion, so that the opposing state of the support shafts can be maintained elastically.

  However, the cylindrical portions (or the fixed shaft cylindrical portion) are fitted into the fixed shaft cylindrical portion (or the supporting shaft cylindrical portion) so as to be rotatable to the end stepped portion thereof. The dimensions may be restricted by the end edge step portion, and the fitting outer peripheral surfaces of the cylindrical portions may be substantially flush with each other.

  Further, a support shaft cylinder portion (or fixed shaft tube portion) having a locking hole is rotatably fitted in the fixed shaft tube portion (or support shaft tube portion), and the fixed shaft (or support shaft is supported in the locking hole). The locking member is loosely inserted and fixed from the side surface of the shaft), thereby strengthening the retaining of the tubular portions in the fitted state, and with the rotation of the support shaft with respect to the fixed shaft, You may make it possible to restrict | limit the rotation angle of a spindle by making a side edge contact | abut to a locking member.

  The outer peripheral surface of the support tube portion (or fixed shaft tube portion) is a non-cylindrical outer surface that is inscribed in at least three cylindrical inner peripheral surfaces of the fixed shaft tube portion (or support shaft tube portion). Alternatively, the inner peripheral surface of the fixed shaft tube portion may be a cylindrical inner surface that circumscribes at least three non-cylindrical outer peripheral surfaces of the fixed shaft tube portion (or the support shaft tube portion), and is bent to one end of the support shaft. A support shaft in which an existing portion is formed and a cylindrical portion is formed on the upper portion may be used. Further, as the torsional restoring elastic body, a torsional restoring elastic body in which a flexible restoring resin is formed into a columnar shape, or expansion and contraction. A coil spring having a small property may be used.

  According to the present invention, there is no robust pivot part that can sufficiently withstand disturbances such as unnecessary external force by reinforcing the pivot part of the fixed shaft and the roll paper spindle by the fitting pivot structure of the cylindrical parts. Since it has been obtained, the fixed shaft and the roll paper support shaft are each made of a thin and smart bar, which is robust. Even if it is used in a random manner, it does not break down and can be used stably over a long period of time.

  Further, the roll paper holder of the present invention is provided by the twisting force in the front-rear circumferential direction of each support tube cylinder part due to the roll paper insertion external force applied to the pair of support shafts from the front side or the empty core tube removal external force. After the elastic body is twisted in the circumferential direction against the torsional restoring elasticity and the restoring elasticity is accumulated, the elasticity associated with the release of each external force when the roll paper is completely inserted or when the empty core tube is completely removed Since the pair of support shafts can be elastically returned to each other with the stored twisted restoring elasticity of the body, the roll paper support setting work or the empty core tube removal work for the pair of left and right support shafts, Each roll paper or core tube can be executed simply by advancing and retreating with respect to each of the above-mentioned supporting shafts, and can be easily handled with one hand.

  Furthermore, the roll paper holder of the present invention requires the execution space for the roll paper set described above and the execution space for removal of the empty core tube, as described above, only on the front side of the roll paper holder. Since it is not necessary at all on either side or one side of the holder, when installing the roll paper holder, it can be installed inside the wall recess or at one corner of the wall, and is not subject to any restrictions due to side walls. There is also an excellent effect.

  In addition to the above, the roll paper support shaft, which is the only movable part in the roll paper holder according to the present invention, can be made as short as necessary in the present invention, and is sufficiently resistant to disturbances such as unnecessary external force by the lever principle. There is also an excellent effect of obtaining.

  As in the third and fourth aspects of the present invention, the support shaft tube portion (or the fixed shaft tube portion) is rotated into the fixed shaft tube portion (or the support shaft tube portion) to the end edge step portion thereof. If it is possible to fit, the fitting dimension of the support cylinder portion with respect to the fixed shaft cylinder portion can be automatically regulated by the end edge step portion, so that a large amount of equal quality products can be easily provided, and Since the fitting outer peripheral surfaces can be made substantially flush with each other, the effect of providing a roll paper holder that is even smarter and unique can be added.

  As in the fifth and sixth aspects of the present invention, the support cylinder (or the fixed cylinder) having the locking hole can be rotated into the fixed cylinder (or the spindle). Is inserted into the locking hole, and the locking member is loosely inserted from the side surface of the fixed shaft (or support shaft) into the locking hole. In addition, the cylinders can be more securely prevented from coming off from each other, and the pivot angle of the support shaft can be adjusted by contacting the side edge of the lock hole and the lock member as the support shaft rotates with respect to the fixed shaft. Since it can be limited, damage due to excessive twisting of the twist-restoring elastic body and so-called elastic settling can be prevented, so that it is possible to add an effect of preventing the occurrence of an opposing error of the roll paper spindle.

  As in the inventions of the seventh aspect to the tenth aspect of the present invention, the outer peripheral surface of the support cylinder portion (or the fixed shaft cylinder portion) is the same as the cylindrical inner peripheral surface of the fixed shaft cylinder portion (or the support cylinder portion). The non-cylindrical outer peripheral surface inscribed in at least three locations, or the inner peripheral surface of the spindle cylindrical portion (or fixed shaft cylindrical portion) at least three locations on the non-cylindrical outer peripheral surface of the fixed shaft cylindrical portion (or spindle cylindrical portion) When the circumscribed cylindrical inner peripheral surface is used, the degree of freedom of selection of the outer peripheral surface shape and the inner peripheral surface shape of the support shaft cylindrical portion or the fixed shaft cylindrical portion is improved, and the effect that it becomes easier to implement can be added.

  As in the invention of claim 11 in the present invention, if a support shaft in which a curved extension portion is formed at one end of the support shaft and a cylindrical portion is formed on the upper end of the support shaft is used, Since there is a curved extension without corners, it was gentle to fingers even when touched, and it was possible to add an effect that it was easy to handle.

  Further, the torsional restoring elastic body obtained by forming the flexible restoring resin in each of the inventions of the twelfth and thirteenth aspects of the present invention into a columnar shape and the torsional restoring elastic body by a coil spring having low stretchability are respectively made of materials. By selecting the thickness and length, the stretchability can be reduced practically without losing the torsional restoring elastic force, so each fixed part near both ends of the fixed shaft cylinder part and the support shaft in the above-mentioned fitted state respectively. By fixing to the tube portion, the opposing state of the support shafts can be elastically maintained, and the twisted restoring elastic body itself is in a pivoted support state without interfering with the opposing return action of the support shafts. The effect that the cylindrical portions can be prevented from coming off can be added.

  Next, a description will be given of an example of the best mode for carrying out the present invention. A pair of left and right bars 1 as shown in FIG. The cylindrical tube portion 5 formed upright as shown in FIG. 2 in the cylindrical tube portion 3 formed as shown in FIG. 2 at the lower portion of the fixed shaft and at one end of a pair of short roll paper support shafts 4. After inserting the columnar torsional restoring elastic body 6 as shown in FIGS. 3 (a) and 3 (b) into the inside, the support cylinder part 5 is inserted into the fixed axis cylinder part 3 as shown in FIG. 4. By inserting deeply into the end edge step portion 5A of the cylindrical portion 5 coaxially with the elastic body 6 inside, the support shaft 4 is pivotally fitted to and supported by the pair of left and right fixed shafts 2 respectively.

  Next, with the pair of left and right support shafts facing each other as shown in FIG. 4, a horizontal hole 3 </ b> A of the fixed shaft cylinder portion 3 and a horizontal hole 5 </ b> B of the support shaft cylinder portion 5 as shown in FIGS. 2 and 4. From the vicinity of the tip end of a stop pin P (or a male screw, usually referred to as an immobilizer) passed through a horizontal hole 6B provided in each of the upper and lower fixing portions 6A of the elastic body 6 as shown in FIG. By caulking or press-fitting (or screwing) into the horizontal holes 3A and 5B on the opposite side of 3.5, the upper and lower fixed parts 6A of the elastic body 6 are respectively connected to the cylinders 3 and 5 in the cylinder parts 3 and 5, respectively. The roll paper support shaft 4 can be pivotally supported with respect to the fixed shaft 2 so as to be able to rotate.

  Therefore, the vicinity of the center of the elastic body 6 remains free, and the fitting pivots as shown in FIGS. 5 and 6 are fitted to the fixed shafts 2 at the bottom of the pair of left and right bars fixed as shown in FIG. The opposed state of the supported roll paper spindles can be maintained elastically by the twisting and restoring elasticity of the elastic body 6 as shown in the above drawings, and the roll paper can be provided by means described later between the pair of left and right opposed spindles 4. By inserting the 7 air cores 7A or the core tube 7B as shown in FIG. 7, a roll paper holder according to the present invention that can rotatably support the roll paper 7 on each spindle 4 as shown in FIG.

  However, in FIG. 1, the member denoted by reference numeral 8 is a known paper cutting board having a front edge 8A, and when this paper cutting board 8 is used, it projects on the rear lower surface of the paper cutting board 8. By passing the pivot support holes 8C provided in the pair of left and right protrusions 8B through the pair of left and right bars 1 as shown in FIG. 1, the pivots are pivotally supported in an obliquely upward and downward direction as shown by arrows in FIG. Use.

  2 and 8, the member denoted by reference numeral 9 is a member formed by making the upper side orthogonal to the cylinder axis in the approximately 2/3 circumference range portion of the spindle cylinder 5 on the spindle 4 side. It is a hole.

  Next, a specific example of attaching the roll paper holder according to the present invention to a mounting surface a such as a toilet wall surface will be described. As shown in FIG. After passing through the pivotal support hole 8C, with the inner ends of the bars 1 facing each other, the in-groove protrusion 10A that presses the positioning notch 1A formed on the peripheral surface of the bar 1 at the facing portion. 1 and the front and rear fixed cylinders 10 divided into the front and rear parts as shown in FIG. 1, after the rear fixed cylinder 10 is put on the opposing approaching part of the bar 1 as shown in FIG. As shown in FIG. 6, a set screw N is passed through the horizontal hole 10B of the rear fixed cylinder 10 and the horizontal hole 1B of the bar 1 as shown in FIG. The left and right bars 1 are screwed to 10C and fixed to the fixed cylinder 10 with screws as shown in FIGS.

  A front side recess 11A of a cylindrical spacer 11 as shown in FIG. 1 is inserted into the rear projection 10D of the fixed cylinder 10, and the spacer 11 and the center hole of the mounting seat 12 disposed behind the spacer 11 are inserted. After screwing and fixing to the rear screw hole 10C of the fixed cylinder 10 through a long set screw N as shown in FIG. 1 as shown in FIG. 9, the mounting seat 12 is attached to a mounting surface a such as a toilet wall as shown in FIG. The fixing seat 13 fixed with a set screw N such as a conical screw is attached.

  That is, the rear surface of the attachment portion 13A formed by bending the upper portion of the fixed seat 13 forward as shown in FIGS. 1 and 9 is hooked to the edge of the upper inner surface recess 12A of the mounting seat 12 as shown in FIG. 9A and 9B, the rear surface of the attachment portion 13A formed by bending the lower portion of the fixed seat 13 forward with a set screw N called a normal imobis screwed into the vertical screw hole 12B in the lower portion of the mounting seat 12 after engagement. The roll paper holder according to the present invention having the roll paper support shaft 4 pivotally supported on the fixed shaft 2 at the lower part of the pair of left and right bars 1 by pressing as shown in FIG. For example, it can be attached at a forward inclination angle of about 5 °.

  However, the rear fixed cylinder 10, the spacer 11, and the mounting seat 12 may be integrally formed, and the portion corresponding to the mounting seat may be directly fixed to the mounting surface “a” with a conical screw or the like. The roll paper holder according to the present invention can be attached to the attachment surface a, the wall surface recess or the like at a predetermined attachment angle by the bar attachment means.

  Next, a specific method of making the fixed shaft 2 and the roll paper support shaft 4 used in the present invention and a specific example of the torsional restoring elastic body 6 will be described in detail. First, the pair of left and right fixed shafts 2 are made of, for example, stainless steel. A round hole with a depth of about 15 mm is formed from one end of a round straight rod 1 having a diameter of about 10 mm and a length of about 150 to 200 mm made of a high-quality metal such as a lathe in the axial direction with a lathe. After forming the cylindrical fixed shaft cylinder portion 3 as shown in FIG. 1, the central portion of the bar 1 is smoothly bent substantially at right angles as shown in the above figures by a high pressure press machine or the like to form a pair of left and right fixed shafts 2. In this case, the fixed shaft tube portion 3 may be formed after the bar 1 is bent as shown in the above drawings.

  On the other hand, in order to make the pair of left and right roll paper spindles 4, the axis line extends from one end of a round straight bar 1 having a diameter of about 10 mm and a length of about 50 to 70 mm, which is beautifully made of the same material as that of the fixed shaft 2. A round hole having a depth of about 15 mm is formed by a lathe in the direction to form a cylindrical spindle cylinder portion 5 as shown in FIG. 1, and then a portion corresponding to the vicinity of the outer end of each spindle 4 is subjected to high pressure pressing. A pair of left and right roll paper spindles 4 as shown in the above figures, in which a cylindrical portion 5 is erected and formed at one end by making it stand at a substantially right angle as shown in FIGS. Alternatively, the support cylinder portion 5 may be formed after raising the vicinity of one end of each support shaft 4.

  Next, the torsional restoring elastic body 6 used in the present invention is a soft plastic having a torsional restoring elasticity, such as polyester elastomer, and having a low elasticity, for example, a circle having a diameter of about 3 to 5 mm and a length of about 12 to 17 mm. A torsion-restoring elastic body formed by forming in a columnar shape is used. In the molding, as shown in FIGS. 3 (a) and 3 (b), block-shaped fixing portions 6A and horizontal holes 6B and elastic bodies near the upper and lower ends are used. It is formed into a cylindrical shape together with a longitudinally long hole (or a longitudinally long groove) 6C for releasing the drawing deformation as shown in FIGS. 3A and 3B when the central portion is twisted.

  The elastic body 6 has an expansion / contraction strength that cannot be easily expanded / contracted with the force of the fingers having the fixing portions 6A at both ends thereof, and each of the fixing portions 6A is strongly twisted in the circumferential direction by the force of the fingers. For example, as shown in FIGS. 3 (c) and 3 (d), the deformation of the diaphragm when the elastic body is twisted is allowed to escape into the longitudinally long hole (or longitudinally elongated groove) 6 </ b> C, and approximately 90 ° in the circumferential direction. 3A and FIG. 3B, the elastic body 6 has a torsional stress that can be twisted one by one, and if the finger is released from the fixing portion 6A after twisting, the elastic body 6 has a considerably strong self-torsion restoring elasticity. Make it return to the original cylindrical shape.

  The basic structure of the present invention is as described above. However, as a more preferred embodiment, a support cylinder is formed from a screw hole 3B provided on the peripheral surface of the fixed shaft cylinder 3 as shown in FIGS. A locking member n such as a male screw, usually called “imobis”, is loosely inserted in the locking hole 9 provided in the portion 5 as shown in FIGS. 5 and 8A, and the locking member n in the loosely inserted state is painted. It locks immovably by well-known localization means such as a lock.

  In this way, the upper side 9A of the locking hole 9 can be brought into contact with the upper peripheral surface of the locking member n as shown in FIG. 8A, the front and rear side edges 9B of the locking holes 9 at the front and rear equal positions as shown in FIG. 8b and 8c, it comes into contact with the side surface of the locking member n and becomes immobile, so that the rotation angle of the support shaft 4 with respect to the fixed shaft 2 is set in the forward and reverse directions. Each can be limited to less than a right angle, for example.

  Therefore, in this case, since the twist angle in the circumferential direction of the twist restoring elastic body 6 can also be limited to less than a right angle as shown in the above drawings, the twist restoring elastic body 6 is damaged or reduced in elasticity by excessive twist. It is possible to further prevent fluctuations in the opposed return position of the support shaft 4 and occurrence of opposed errors due to so-called elastic settling.

  The specific embodiment of the roll paper holder according to the present invention is configured as described above. In using this, the roll paper 7 is first pivotally set to the pair of left and right roll paper spindles 4 in the opposed state. For this purpose, when the roll paper 7 is pushed inward as shown in FIG. 10 while the rear outer peripheral surface of the roll paper 7 is applied to the front surface of the opposed support shaft 4, the pair of left and right roll paper support shafts 4 are respectively Against the torsional restoring elasticity of the torsional restoring elastic body 6, it is pushed obliquely rearward as shown in the figure and pivots obliquely backwards as shown in FIG.

  As the pair of support shafts 5 rotate, the elastic body 6 is twisted by about 90 ° in the circumferential direction from the initial state of the cylinder shown in FIGS. 3A and 3B, as shown in FIG. The central portion of the elastic body 6 is squeezed into a small drum-shaped outline, and the diaphragm deformation is squeezed as shown in FIG. It becomes the state where the elasticity is stored.

  Thereafter, when the roll paper 7 is continuously pushed in, when the tip of each spindle 4 faces the side of the roll paper air core 7A or the core tube 7B as shown in FIGS. Therefore, the pair of left and right roll paper support shafts 4 is rotated inwardly around the cylindrical portion 5 by the torsional restoring elasticity stored in the elastic body 6, respectively. In the roll paper core 7A or the core tube 7B, the opposed state is restored as shown in FIGS. 7, 9, and 13, and the opposed state can be maintained by the torsional restoring elasticity of the elastic body 6. It is possible to ensure that the upper surface of the inner surface of the roll paper core 7A or the core tube 7B is placed on the upper surface as shown in FIGS. 7 and 9, and the roll paper 7 is rotatably supported by the left and right support shafts 4 as shown above. Yes, you can set the roll paper 7 to the roll paper holder It can be realized only by hand.

  After that, if the roll paper start end is pulled forward, the roll paper 7 can be fed out for a desired length while rotating around the left and right support shafts 4, so that the roll paper 7 that has been fed out can be shredded with fingers and used. When 8 is used, the roll paper 7 fed out can be cut and used by the front edge 8A of the paper cutting plate 8 brought into contact with the front outer peripheral surface of the roll paper 7 as shown in FIG.

  To remove the empty core tube 7B from the pair of left and right support shafts 4 after drawing out all the paper, the core tube 7B is pulled directly forward while the rear inner surface of the core tube 7B is applied to the rear surface with one hand. The pair of left and right roll paper spindles 4 respectively resist the restoring elasticity of the twisted restoring elastic body 6 at the outer edge of the core tube 7B, and rotate obliquely forward about the cylindrical portion 5 as shown in FIG. The elastic body 6 is twisted by about 90 ° in the circumferential direction as shown in FIGS. 3D and 8C by this rotational force, and the elastic body 6 is twisted to be in a state of storing the restoring elasticity.

  When the core tube 7B escapes from the pair of roll paper support shafts 4, the external force due to the core tube 7B applied to the support shaft 4 is lost. Since the roll paper support shaft 4 is opposed to the outside of the core tube 7B around the cylindrical portion 5, the roll paper support shaft 4 can cope with the next setting operation of the roll paper 7 and the removal operation of the core tube 7B of the roll paper 7 which has been used up. As with the roll paper setting operation, it could be realized with only one hand.

  As described above, the execution space for setting the roll paper 7 on the roll paper holder according to the present invention and the execution space for removing the used roll paper core tube 7B are only on the front side of the roll paper holder. Since it is necessary and is not required on either side or one side of the roll paper holder, it can be installed in the wall recess or in one corner of the wall surface when selecting the installation location of the roll paper holder according to the present invention. It is not subject to any restrictions.

  In addition, the roll paper 7 is set on the pair of left and right support shafts 4 as described above, or the empty core tube 7B is removed from the roll paper 7 or the core tube 7B with respect to each support shaft 4, respectively. It can be executed by simply moving forward and backward.

  The roll paper holder according to the present invention can be used not only in the horizontal installation as described above, but also in the vertical or oblique installation with respect to the mounting surface a as shown in FIG. The support shaft 4 may be made by die-casting a metal instead of being made of a bar, or by injection-molding a plastic molding material.

  Further, if the support shaft tube portion 5 (or the fixed shaft tube portion 3) is rotatably fitted in the fixed shaft tube portion (or the support shaft tube portion) to the end edge step portion thereof, the tube portions are pivotally supported. The fitting dimension of the support cylinder part with respect to the fixed axis cylinder part can be automatically regulated by the end edge step part, and the fitting outer peripheral surfaces of the cylinder parts can be substantially flush with each other.

  At one end of the support shaft 4, a narrow cylindrical portion 5C thinner than the support shaft is erected as shown in FIG. 17, and the thin cylindrical portion is fitted into the cylindrical portion 3 of the fixed shaft 2 as shown in FIG. The tube portions may be fitted and supported, and conversely, a thin tube portion is formed at one end of the fixed shaft, and this tube portion is fitted into the tube portion 5 of the support shaft 4 to each tube. The parts may be fitted and supported.

  Further, the outer peripheral surface of the support cylinder portion 5 (or the fixed shaft cylinder portion 3) is a non-cylindrical outer peripheral surface that is inscribed in at least three cylindrical inner peripheral surfaces of the fixed shaft cylinder portion 3 (or the support shaft cylinder portion 5). The inner peripheral surface of the support shaft cylinder portion 5 (or the fixed shaft tube portion 3) is made to be a cylindrical inner peripheral surface circumscribing at least three non-cylindrical outer peripheral surfaces of the fixed shaft tube portion 3 (or the support shaft tube portion 5). For example, the degree of freedom in selecting the outer peripheral surface shape and the inner peripheral surface shape of the support shaft tube portion 5 or the fixed shaft tube portion 3 is improved.

  If a support shaft 4 having a curved extension portion 4A as shown in FIG. 18 formed at one end of the support shaft 4 and a cylindrical portion 5 formed thereon is used, the roll paper 7 supported by the support shaft 4 has a side. Since the curved extension portion 4A that is kind to fingers is present, it can be handled safely and easily even if touched.

  Another embodiment of the twist restoring elastic body 6 used in the present invention is a plastic having twist restoring properties such as a polyacetal synthetic resin (POM resin), and has a block shape near both upper and lower ends as shown in FIG.
