Description

  The present invention holds the small-diameter housing in an extended state drawn from the large-diameter housing by fitting the outer-side fitting surface of the small-diameter housing to the inner-side fitting surface of the large-diameter housing. At the same time, by fitting the outer-side fitting surface of the small-diameter housing to the inner-side fitting surface of the large-diameter housing, the small-diameter housing is brought into a contracted state accommodated in the large-diameter housing. It is related with the telescopic cage to hold.

Originally, as a measure for reducing the feeling of weight and the like as a fishing rod, it is desirable to reduce the diameter of a medium rod or a tip rod as a small-diameter rod. On the other hand, an optimum grip diameter is required for the grip portion of the marshal.
In order to satisfy both of these requirements, there is one that forms a suddenly enlarged portion where the diameter of the heel increases rapidly toward the heel side compared to other parts of the heel at the intermediate position in the heel axis direction of the heel. (See Patent Document 1).
With such a configuration, it is possible to make the diameter of the intermediate collar, such as the original, small while securing a sufficient grip diameter as a grip section of the collar.

Japanese Patent Laying-Open No. 2004-173682 (paragraph number [0059] and FIG. 8)

By the way, as described above, in the case where the rapidly expanding portion is formed at an intermediate position in the heel axis direction of the base rod, the base side outer fitting surface on the base portion is extended from the inside of the base rod. The outer diameter of the heel-side outer fitting surface on the former is approximately the same as the inner diameter of the heel-side inner fitting surface of the former. Is set.
Then, the large-diameter intermediate portion located on the heel side from the rapidly expanding portion has a larger diameter than the heel side inner fitting surface and the heel side inner fitting surface, while the heel side inner fitting surface of the heel side and The outer diameter of the base outer side fitting surface, which has the same diameter as the inner side fitting surface, is considerably smaller than the inner diameter of the large diameter intermediate part. A large gap is formed between the peripheral surface and the upper flange-side outer fitting surface.
In such a relationship between the base and the base, when the base is switched from the base to the extended state, the base end of the base is suddenly released from the restrained state. In addition, the angler added a momentum that pulled out the former with the operating force against the holding force that the marshal holds the former, causing the former to cause a large misalignment state with respect to the former, The outer peripheral surface of the heel-side outer fitting portion on the base may impactly contact the inner surface of the large-diameter intermediate portion of the base heel.
In such a case, an impact sound is generated, and the impact force is transmitted to the hand of the angler holding the base, and the angler may feel uncomfortable.

  The purpose of the present invention is that even when the outer peripheral surface of the outer side fitting portion of the small-diameter casing is in contact with the inner surface of the large-diameter intermediate portion of the large-diameter casing during the extension operation of the small-diameter casing, The object is to provide a telescopic rod that can relieve the impact force, suppress the generation of impact sound, and eliminate the discomfort of the angler.
