[Prior Art] In the above-described pull-out type fishing rod, a resin paint projection is formed on the outer peripheral surface of the tail end of the small-diameter body to be crimped to the inner peripheral surface of the front end of the large-diameter body. To form the joint. By forming the projections to allow moisture to move between the projections, there are advantages as described below. For example, the outer peripheral surface of the dovetail end of the small-diameter element body is formed into a flat surface, and is formed in a state in which the outer peripheral surface is integrally pressed against the inner peripheral surface of the dammed tip end of the large-diameter cymbal body. As a result, when the water permeates into the portions that are pressed against each other, the crimped portion becomes tighter, and the tightened state in which the small-diameter body cannot be returned from the extracted state to the original stored state is exhibited. On the other hand, if a projection is formed, even if moisture penetrates, the moisture will move away from the projection and disappear, and the fastening state will not be exhibited. [Patent Document 1] Japanese Laid-Open Patent Publication No. Hei 6-205626 (paragraph No. [0018], [0019] FIG. 1 and FIG. 3) [Description of the Invention] -4-201010600 [Problems to be Solved by the Invention] This effect is achieved, but the protrusions are made of a coating of the same material. If the protrusion is too hard, the flexibility is lacking. In this way, it is necessary to appropriately set the height of the circumferential surface of the object side to be pressed against the target side surface with an appropriate pressure, which requires precise dimensional management and a large manufacturing burden. . On the other hand, if the protrusion I is made of a material having flexibility, precise dimensional management is not required, and although the negative load is reduced as described above, it is found that the crimping force is lowered during long-term use, and durability is obtained. There will be problems in the aspect. SUMMARY OF THE INVENTION An object of the present invention is to provide a draw-type fishing rod capable of avoiding a fastening phenomenon in advance and having a joint portion having a small production load and excellent durability. [Means for Solving the Problem] Φ [_' Manufactured] The characteristic structure of the first aspect of the invention is a joint portion for maintaining a state in which a small-diameter body is extracted with respect to a large-diameter body, and the joint portion is shaped A hard protrusion protruding toward the target side circumferential surface from the inner circumferential surface of the large-diameter body or the outer circumferential surface of the small-diameter body, and being softer than the hard protrusion a soft protrusion formed of a material of the material; and a protrusion height of the hard protrusion protruding toward the target side circumferential surface is formed to be the same height or lower than a protrusion height of the soft protrusion that protrudes toward the target side circumferential surface The height; its effect is as follows -5 - 201010600. [Operation] By forming a soft protrusion and a hard protrusion as protrusions, it is not necessary to form a hard protrusion, and the protrusion height of the protrusion should be closely managed. On the other hand, there is no problem that the durability is deteriorated as compared with the case where only soft protrusions are formed. When the soft protrusion is pressed against the target side peripheral surface and is deflected by the elastic deformation force, the hard protrusion is brought into contact with the target side peripheral surface, so that the soft protrusion can be softly crimped, and It allows the hard protrusions to exert a supporting force and ensures a firm crimping state. [Effects] As a result, by forming the protrusions, the fastening phenomenon due to the adhesion of water can be prevented in advance, and when the small-diameter body is maintained in the extracted state, the soft protrusion can be stably transferred to the extracted state. Moreover, the durability can be improved by stably maintaining the extracted state by the hard protrusion. According to a second aspect of the invention, a cross-sectional area of the soft protrusion that is in contact with the target side peripheral surface is formed to be larger than a cross-sectional area of the hard protrusion that is in contact with the target side peripheral surface; Its effect is as follows. [Operation] In other words, the cross-sectional area of the protrusion is relatively large, so it can be -6-201010600 so that the shear stress or surface pressure acting on the soft protrusion is small. Even if it is formed as a soft protrusion, durability can be ensured. . On the other hand, the hard protrusion has a small cross-sectional area, and the coating itself has a high mechanical strength, so that the crimping force is not excessively high and a moderate holding force can be maintained. According to a third aspect of the invention, the soft protrusion is formed by a rubber-based paint, and the hard protrusion is formed of a rubber-free paint. The effects are as follows. [Effects] Since the rubber-based paint is used as the soft protrusion, when the soft protrusion is in contact with the peripheral surface of the target side, it is less likely to slide and can maintain the contact state. The soft protrusion and the hard protrusion are projections using the paint as a raw material. A mask having a hole portion is placed at the position where the protrusion is formed, and a protrusion can be formed by a spray coating method, which can be easily produced. [Embodiment] Here, a configuration of a joint portion of a fishing rod used in a squid, etc., will be described. As shown in Fig. 1, an expansion portion 1A is formed at the end of the small diameter body 1 and the outer diameter of the expansion portion 1A is press-fitted to the inner circumferential surface 2A of the front end of the large diameter body 2 (At the stage of the ruthenium material, the degree of coating is estimated to be processed, and the ruthenium material is pressure-bonded by applying a state in which the protrusion 3 is described later. The small-diameter body 1 can be freely advanced and retracted to the large-diameter body 2, and in the extracted state, the inflation portion ία is crimped to the inner circumferential surface 2A of the front end circular opening of the 10201010600, and the extraction 竿 can be fixed in this state. A part of the expansion portion 1A covers the outer peripheral surface and is formed integrally with a plurality of projections 3' formed by coating. The front end of the projection 3 is pressed against the inner peripheral surface 2A of the front end circle. The joint portion 4 is formed by the expansion portion 1A including the projection 3 and the inner circumferential surface 2A of the front end circle of the crucible. At the leading end of the large-diameter cymbal body 2, the small-diameter cymbal body 1 is protruded toward the small-diameter side in the axial direction of the expansion portion ία. Next, a method of manufacturing the joint portion 4 will be described. (1) The honing process is performed on the rear end outer expansion portion ' of the enamel material formed in other steps, and the ruthenium material itself is in the following manner. The prepreg sheet in which the carbon fiber is used as the reinforcing fiber and immersed in the thermosetting resin is repeatedly wound around the mandrel to form a conical tubular body. The auxiliary mold made of the prepreg sheet is wound around the rear end of the tubular body, and the expansion is performed. Department, as a material. The formed niobium material was honed by a coreless machine. For the expansion part, honing is performed by other coreless shaft machining. (2) The enamel material 6 which completes the honing step is subjected to primer coating by a die coating coater. (3) The honing process is performed again after the primer coating, and the surface after the coating is polished. (4) Next, as shown in Fig. 2(a), a table-mask tape 7 made of paper (resin) is applied to the expansion portion to cover the swell portion ία. The first mask tape 7 is formed with a plurality of through holes 7A. The through hole 7A is a manufacturing-formed surface forming surface for forming an opening of the hard fishing material to be described later among the projections 3, and the projection forming shaft is inserted into the base 1A, and the projection -8-201010600 3 A, Therefore, the aperture is small. A plurality of through-holes 7 A ' along the circumferential direction are provided in two columns covering the axial direction. (5) In the state in which the first mask tape 7 is attached, as shown in Fig. 2(b), the spray gun 5 is used for the blow coating. The coating used here is a coating which is usually used. A representative material is a coating material of propylene or polyurethane, which has a good compactness and exhibits a predetermined hardness in a state of being hardened after application. The state in which the coating material is cured after the blow coating is provided with a hardness of 2H or more in the pencil core hardness. Although it is blown and sprayed, it can also be coated with (die if). (6) After the blow coating is performed, the first mask tape 7 is peeled off. As shown in Fig. 2(C), a plurality of hard protrusions 3A can be formed in the expanded portion 1A of the small-diameter body 1. (7) Next, as shown in Fig. 2(c), the second mask tape 8 is attached to the formation portion of the hard protrusion 3A. The second mask tape 8 is formed with a through hole 8A having a larger diameter than the through hole 7A formed in the first mask tape 7. The through hole 8A is disposed at three positions in the axial direction so as to sandwich the hard protrusion 3A. The second mask tape 8 is paper (resin) or the like. (8) If not shown in Fig. 2(c), the second mask tape 8 is attached in the same manner as shown in Fig. 2(b), and the spray gun 5 is used for the blowing process. The coating used here is a rubber-based paint, and a soft polyester-type polyurethane resin paint is used. This paint is sold in Japan. The product name "seven yy 7 Bu 8" manufactured by CASHEW. Other materials may be used as long as they are of the same nature. This coating is very soft and elastic. -9- 201010600 After the blowing process is performed by the spray gun 5 and then the second mask tape 8 is removed, as shown in Fig. 1, the soft protrusion 3B with the hard protrusion 3A interposed therebetween is formed. The hard projection 3A and the soft projection 3B have a large cross-sectional area of the soft projection 3B, and the height protruding from the circumferential surface is also higher than the soft projection 3B. (9) After the main coating is performed, the finishing processing is performed by the cleaning process, and the protrusions 3 are subjected to the finishing processing for forming the fitting diameter to a predetermined size to form the cartridges 1, 2. [Other Embodiments] (1) Although the protrusions 3 are formed using the mask tapes 7, 8 and the blow-coating method, the protrusions 3 may be formed individually, and are fixed to a small diameter by an adhesive or the like. The expansion portion 1A of the body 1. (2) Although the protrusion 3 is provided in the protruding portion 1A of the small-diameter body 1, it may be provided on the inner peripheral surface 2A of the large-diameter body 2, or its φ may be set in the expansion portion 1A and the inner circumference. Face 2A both sides. (3) Although the soft protrusion 3B is made larger than the hard protrusion 3A, the sectional area thereof may be made the same. A plurality of soft protrusions 3B or a plurality of hard protrusions 3A may be provided, and the cross-sectional areas of the respective protrusions 3A and 3B may be set to be different. (4) Although the height of the soft protrusion 3B protruding from the surface of the inflation portion 1A is made higher than that of the hard protrusion 3A from the surface of the inflation portion ία, the same protrusion height can be formed. -10- 201010600 [Simple description of the drawing] ‘The first drawing is a longitudinal sectional side view showing the joint portion.
