[Problems to be solved by the device]

 However, in the case of a draw-out fishing rod, when each rod pipe is drawn out, it is not necessarily constructed such that the rod rod is drawn out successively from the medium diameter rod pipe of a small diameter, and then the rod pipe is spliced out. However, there was a problem that it was difficult to prepare for fishing smoothly and quickly. Further, in the case of using the annular component as described above, if a large number of middle rod pipes are housed in the original rod pipe, the clearance between the rod pipes is small, which is practically impossible in terms of dimensions, and the structure is complicated. However, there are drawbacks such as an increase in size, an inability to adhere and fix annular parts, and poor durability. In addition, in the above proposal, it is difficult to fit the annular projection into the clearance between the rod tubes, it is difficult to fit the rod tube into the cylindrical projection with a large surface area, and with the mountain-shaped projection, the closing dimension becomes longer when the angle is acute, When the angle is obtuse, there is a drawback that the rod tube cannot be fully locked.

[0004] Accordingly, an object of the present invention is to provide a swing-out fishing rod that facilitates the pulling and joining operation of each rod tube. Further, in addition to the above object, it is another object of the present invention to provide a swing-out fishing rod that can be easily and reliably locked in the housed state even if the clearance between the rod tubes is small.

The tube is locked by a force that does not come off due to the action of gravity, and each locking force is configured to be stronger than the middle rod tube located outside. Further, in claim 2, the two or more middle rod pipes are locked by means of a rod end part provided at a rod end of the original rod pipe and a base portion of the middle rod pipe, in addition to the base portions of the adjacent rod pipes. Deformation of the cross-sectional shape by forming a protrusion on at least a part of the circumference of at least one of the inner side and the outer side adjacent to each other, and press-fitting the protrusion on the other. It is configured to be locked by.

According to the first aspect of the present invention, in the stored state, first, the tip rod tube can be pulled out by grasping the tip portion, or can be pulled out by its own weight. The locking force of each locked middle rod pipe is stronger as the outer middle rod pipe is positioned, and even if there is an unlocked middle rod pipe, the larger middle rod rod is heavier. It is possible to set so that the smallest middle rod pipe following the tip rod can be pulled out by simply pulling the tip rod, and the small diameter medium rod pipes inside can be successively pulled out and joined. According to the second aspect of the present invention, the same action as described above is achieved, but since the projecting portion formed on a part of the circumference is pressed to the other side to deform and lock the cross-sectional shape, the clearance between the rod tubes is cleared. Even if it is small, it can be locked easily and securely.
