DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an improvement in a fishing rod capable of holding a middle rod without change with time in a stored state of a swing-out fishing rod.

[0002]

2. Description of the Related Art In a conventional fishing rod which does not prevent the middle rod from coming off, when the middle rod is housed in the former rod and is lightly locked and held, when the fishing rod is moved with the former rod. When the middle rod slides out and breaks the tip of the front rod, or when moving the fishing spot by holding the tip of the middle rod or transporting the fishing rod, the former rod falls off and is attached to the former rod or its base end. There is a risk that the butt plug may be damaged, and in order to prevent the falling off, the rear end of the storage rod tube is constantly pressed by an elastic member provided at the rear end of the main rod, for example, in Japanese Patent Application Laid-Open No. 7-255332. A configuration such as force holding is shown. However,
Since the above configuration is held by the urging force due to the elastic deformation of the elastic member, if the fishing rod is not used for a long time and the storage state is long, the deformation state may remain, or if abrasion occurs due to the storage and withdrawal operation, There is a possibility that the holding force is reduced or an operation failure occurs.

[0003]

The problem to be solved is that if the stored state is maintained for a long period of time while being constantly urged by the elastic deformation of the elastic member, the elastic member undergoes a temporal change and the holding force is changed. However, there is a drawback that the locking force is reduced or malfunction occurs due to abrasion if the pressure is reduced or is constantly urged.

SUMMARY OF THE INVENTION In view of the above-mentioned drawbacks, an object of the present invention is to provide a fishing rod which can be reliably held in a housed state, and in which the urging force is not always applied to reduce a decrease in holding force due to aging or abrasion and a malfunction. It is to be.

[0005]

SUMMARY OF THE INVENTION In order to solve the above-mentioned problems, the present invention according to claim 1 is a fishing rod used by splicing a rod pipe in a swing-out manner, wherein the rod pipe is housed in the rod pipe. An elastic projection is provided on one of the rod pipes, and a fitting concave part is formed on the other of the rod pipe, the fitting concave part being fitted to the projection when stored, and relatively restricting axial movement of the rod pipe. The mating recess is formed to be larger than the size of the projection at the time of fitting with the projection.
