A fishing line locking portion capable of locking one end of a fishing line is provided at the tip end side of a conventional fishing rod. This conventional fishing line locking portion is a thin tubular bendable thread-like member made of synthetic fiber such as nylon fiber (a portion called “snake mouth”). When fishing, the fishing line is locked to the fishing line locking portion. Then, the fishing line locking portion also rotates together with the fluctuation and rotation of the fishing line to suppress the entanglement.
[0003]
[Problems to be solved by the invention]
When fishing, a so-called root may be caused in which a fishhook is caught on an obstacle such as a rocky bottom of the water. If the fishing line is pulled up so as to collect the fishhook when the root is engaged, an excessive load may be applied to the rod and the rod may be damaged.
Such a breakage of the rod may occur similarly when a large fish is caught on the fishhook.
[0004]
An object of the present invention is to provide a fishing rod capable of preventing damage to the rod body when an excessive load is applied.
[0005]
[Means for Solving the Problems]

And a locking portion that can lock the auxiliary yarn. And the latching | locking part has the latch release means which cancels | releases the latching to the latching | locking part of an auxiliary thread, when the load more than a setting value is added to the auxiliary thread | yarn.
[0006]
In this fishing rod, fishing is carried out by locking the fishing line to the tip of the auxiliary line connected to the auxiliary line connecting part and locking the auxiliary line to the engaging part. If a fishhook at the tip of the fishing line causes a root or an unexpected large fish catches and a load exceeding the set value is applied to the auxiliary thread via the fishing line, the unlocking means assists the locking part. Release the thread lock. Since the user can recognize that an excessive load is applied by releasing the auxiliary thread to the locking portion, the user can release the fishing rod from the load from the fishing line and suppress damage to the fishing rod.
[0007]
This set value is a value set for each fishing rod, and specifically, is a load force value smaller than the flexural strength that the fishing rod can withstand. The bending strength varies depending on the type of the fishing rod. For example, when the bending strength of the fishing rod is about 3 kgw, the set value is about 2.5 to 2.8 kgw.
A fishing rod according to a second aspect of the present invention is the fishing rod according to the first aspect, wherein the auxiliary thread connecting portion is formed at a tip side end portion of the rod body. In addition, the locking portion can be locked by winding the auxiliary thread and increasing the diameter sequentially from the main body portion toward the tip side direction, and a substantially cylindrical main body portion fixed to the end portion on the tip side of the housing.

Here, the main body portion of the locking portion has elasticity that expands when a load of a set value or more is applied to the auxiliary thread, and the locking release means is a spherical body storage portion.
[0010]
When fishing with this fishing rod, one end of the auxiliary thread is connected to the auxiliary thread connecting portion of the butt plug, and the other end of the auxiliary yarn is inserted into the through hole of the locking portion while being inserted through the insertion passage of the rod. The auxiliary thread sphere is locked to the sphere storage portion of the locking portion. And a fishing line is connected with the other end of this auxiliary thread which penetrated the through hole. Here, the auxiliary yarn preferably has a length longer than the axial length of the housing.
[0011]
The sphere storage portion of the locking portion holds the sphere of the auxiliary yarn when a load equal to or less than the set value is applied to the fishing line, and prevents the auxiliary yarn from slipping out toward the tip side. If the fishhook at the tip of the fishing line is rooted, and the load larger than the set value is applied from the fishing line through the auxiliary thread to the diameter-expanding piece toward the tip side, the locking part expands due to its own elasticity. The through-hole expands to release the lock to the sphere in the sphere storage portion. By releasing the lock, the user can recognize that an excessive load is applied, so that the user can release the fishing rod from the load from the fishing line and suppress damage to the fishing rod. In addition, after releasing the locking of the auxiliary yarn, the locking portion returns to the original shape by the elastic force.
