Description

[Detailed Description of the Invention] [Industrial field of application] The present invention relates to a fishing rod that supports the outer side of a small-diameter rod tube by means of two locations inside and outside the large-diameter rod tube.

[Prior art]

In the conventional seaming structure of fishing rods, 1) as shown in FIG. 11, the large-diameter rod pipe 8 and the small-diameter rod pipe 9 are respectively engaged with the slanting tapered engaging projections 9a and the engaging receiving portions 8a. 2) As shown in FIG. 12 and FIG. 13, in the use state of the fishing rod on both sides of the large-diameter rod pipe 8 in parallel with the longitudinal direction, preferably the engagement receiving portion 8b having a vertical surface oriented in the up-down direction and the thin portion. The engaging projection 9b having four polygonal surfaces parallel to the longitudinal direction of the diameter rod tube 9 engages at any position in the longitudinal direction.
As disclosed in Japanese Patent No. 3905, there is one in which a fixing ring is screwed onto the outer circumference of the front side of a large-diameter rod tube, and a retaining ring is fixed to the fixing ring toward the inner circumference.

[Problems to be solved by the invention]

In 1) above, the lengths of the engaging projection and the engaging receiving portion are structurally long, and if the length is short, the engagement state becomes unstable.

In 2), it can be engaged at any position in the longitudinal direction, but when the outer circumference of the small diameter rod tube is a gentle taper, the small diameter rod tube is projected short and the front inner diameter of the large diameter rod tube at the time of joining. There is a gap between the outer side of the small diameter rod pipe and the outside of the small diameter rod pipe, and the small diameter rod pipe may rattle and may make an abnormal noise.

3) With this structure, the fixing ring must be tightened and loosened at all times when the small diameter rod tube is advanced and retracted, and there is a drawback that the engaging operation is troublesome, and the strong pressure that completely kills the elasticity of the retaining ring is small. If the outer circumference of the diameter rod tube is not pressed, it will become loose, and if the outer shape of the small diameter rod tube changes, the engagement force will be insufficient unless the retaining ring is changed, and if the elastic force of the retaining ring decreases over time, the engagement force will decrease. There are shortcomings such as shortage.

In view of the above-mentioned drawbacks, the present invention reliably supports and supports a small-diameter rod tube at the two points of the support body and the engagement of the engagement protrusion and the engagement receiving portion without adjusting the size of the support body at the time of joining. It is to propose a fishing rod to be used.

[Means for solving problems]

The present invention provides a structure for solving the above-mentioned problems, in a fishing rod in which a plurality of fishing rods are spliced, an engagement receiving portion formed on the inner side near one end of a large diameter rod pipe, and a small diameter rod pipe end portion. The joint is joined by engagement with an engaging protrusion formed on the outer side, and bulges inside the large-diameter rod tube, and the engaging protrusion is removed closer to the one end than the engagement receiving portion. The gist is that a thick portion having an inner diameter larger than the outer diameter of the thin rod tube is formed, and a support body that elastically supports the outer side of the thin rod tube is provided in the thick portion. .
