  However, in the fishing rod with a bottom plug disclosed in Patent Document 1, the contact surface on the fishing rod side and the contact surface on the bottom plug side face each other in front of each other (the contact surfaces are in contact with the longitudinal axis of the fishing rod). Therefore, since the contact surface is difficult to be wide, it is not possible to sufficiently prevent rotation by the contact surface. For this reason, the butt plug may be loosened.

  The present invention has been made paying attention to the above circumstances, and the object of the present invention is a fishing rod in which a butt plug is screwed, which can secure a sufficient anti-rotation by the contact surface, and the butt plug is loosened. An object of the present invention is to provide a fishing rod that can prevent the above.

  In order to solve the above-mentioned problem, the invention according to claim 1 is a fishing rod having a butt plug that is detachably screwed, and when the butt plug is screwed to the fishing rod, the fishing rod and the butt plug are mutually connected. A contact surface is provided for contact, and the contact surface is inclined with respect to a surface orthogonal to the longitudinal axis of the fishing rod.

  According to the first aspect of the present invention, the contact surface between the fishing rod and the butt plug is inclined with respect to the surface orthogonal to the longitudinal axis of the fishing rod, so the contact between the fishing rod and the butt plug by the contact surface. The portion (contact area) increases (compared to the case of Patent Document 1 in which the contact surface of the fishing rod and the bottom plug is parallel to the surface perpendicular to the longitudinal axis of the fishing rod), and the bottom plug screwed to the fishing rod rotates. It becomes difficult (ensures sufficient detent by the contact surface). Accordingly, loosening of the butt plug is prevented.

  The invention according to claim 2 is characterized in that, in the invention according to claim 1, the contact surfaces of the fishing rod and the bottom plug are both arranged around the longitudinal axis of the fishing rod.

  According to the second aspect of the present invention, the same effect as that of the first aspect of the present invention can be obtained, and the rotation around the contact surface accompanying the rotation of the bottom plug about the longitudinal axis of the fishing rod. Stop can be realized effectively.

  Further, the invention according to claim 3 is the invention according to claim 1 or claim 2, wherein at least one of the fishing rod and the bottom plug is provided with unevenness for rotation prevention. Features.

  According to the third aspect of the invention, the same effect as that of the first or second aspect of the invention can be obtained, and the unevenness of the contact surface strongly hits the contact surface on the other side to The stopper can be effectively prevented from rotating.

  According to a fourth aspect of the invention, there is provided the invention according to any one of the first to third aspects, wherein at least one of the fishing rod and the fitting surface of the bottom plug is a bottom plug on the fishing rod. It is formed of a material that bends when screwed.

  According to the invention described in claim 4, the same effect as that of the invention described in any one of claims 1 to 3 can be obtained, and at least one of the bottom plugs can be screwed together. Since the contact surface is distorted and pressed against the other contact surface (to be pressed against each other), it is possible to effectively prevent the bottom plug from rotating.

  Hereinafter, embodiments of a fishing rod according to the present invention will be specifically described with reference to the accompanying drawings.

  1 to 4 show a first embodiment of the present invention. As shown in FIG. 1, the fishing rod 1 of the present embodiment includes a rod 2, a handle 5 provided at the base of the rod 2, and a bottom plug 10 screwed onto the base of the handle 5. The rod 2 is provided with a plurality of fishing line guides 3 at a predetermined interval along the longitudinal axis O. The handle 5 has a reel mounting portion 4 to which a reel (not shown) is detachably mounted. Note that the base portion of the flange 2 is inserted into the reel mounting portion 4 and the handle 5 and fixed thereto.

  As described above, the butt plug 10 is detachably screwed to the rear end portion of the handle 5, and the butt plug 10 is detached from the handle 5 so as to be placed in the space in the hole at the rear end portion of the handle 5. (Weight) can be stored.

  In the present embodiment, the handle 5 forms the rear end of a fishing rod and is made of a natural material such as wood or balsa or a flexible material such as rubber, synthetic resin (for example, polyurethane, ethylene vinyl acetate, nylon, ABS). ). As shown in FIGS. 2 to 4, the handle 5 is formed with a screw hole 21 having a screw portion extending from the rear end portion thereof along the longitudinal axis O of the fishing rod 1, and this screw hole 21. The bottom plug 10 is detachably screwed. The screw hole 21 may be formed of a material that does not have flexibility.

  The bottom plug 10 is formed of a flexible material such as rubber or synthetic resin (for example, polyurethane, ethylene vinyl acetate, nylon, ABS), and protrudes forward from the cap-shaped plug body 35 and the plug body 35. And a screw rod 32. The stopper body 35 is provided with a peripheral wall portion 36 projecting forward along the periphery of the stopper body 35 so as to make one round, and the inner side surrounded by the peripheral wall portion 36 is a concave portion 39. The inner side of the concave portion 39 defined by the peripheral wall portion 37 has a bank-like shape having an inclined surface 30 (forms a contact surface described later) rising from the inner back of the concave portion 39 toward the upper end (ridge line portion 37) of the peripheral wall portion 37. Is formed. In other words, the inclined surface (degree contact surface) 30 is attached to the fishing rod 1 so as to face away from the longitudinal axis O toward the front end of the fishing rod 1 with respect to the longitudinal axis O, and the longitudinal axis O of the fishing rod 1. It is inclined to the front end side of the fishing rod 1 with respect to a plane orthogonal to (a predetermined angle θ with respect to the longitudinal axis O). In addition, the above-described screw rod 32 having a screw portion on the outer peripheral portion projects from the center of the concave portion 39 toward the front. The screw rod 32 may be formed of a material that does not have flexibility.

  The inclined surface 30 on the inner side of the peripheral wall portion 37 forms a contact surface that contacts the rear end (the contact surface 20 described later) of the handle 5 on the fishing rod 1 side, and surrounds the longitudinal axis O of the fishing rod 1. Arranged in an arc shape (arranged around the longitudinal axis O of the fishing rod 1). In addition, on the contact surface 30, an uneven portion 33 for preventing rotation from the upper end of the peripheral wall (ridge line portion) 37 toward the inner back side of the concave portion 39 so as to make one round along the inner side of the peripheral wall portion 37. Concave and alternating) are formed. The concavo-convex portion 33 has flexibility according to the material forming the bottom plug 10.

  On the other hand, on the outer peripheral surface of the rear end of the handle 5 on the fishing rod 1, there is an inclined surface 20 that rises from the screw hole 21 side (longitudinal axis O side) to the outer peripheral side of the handle 5 from the rear to the front. Is formed. The inclined surface 20 forms a contact surface that contacts the contact surface 30 of the bottom plug 10, and is separated from the longitudinal axis O toward the front end portion of the fishing rod 1 in the same manner as the inclined surface 30 of the bottom plug 10. Inclined to the front end side of the fishing rod 1 with respect to a plane orthogonal to the longitudinal axis O of the fishing rod 1 (which forms a predetermined angle θ with respect to the longitudinal axis O) and the longitudinal axis O of the fishing rod 1 Are arranged in an arc shape (arranged around the longitudinal axis O of the fishing rod 1). In addition, the contact surface 20 is formed with a non-rotating uneven portion 23 (protrusions and recesses are alternately connected) so as to make one turn along the outer periphery thereof. This uneven portion 23 also has flexibility according to the material forming the handle 5.

  Therefore, in the configuration as described above, the bottom plug 10 is attached to the fishing rod 1 by inserting the screw rod 32 of the bottom plug 10 into the screw hole 21 at the rear end of the handle 5 and the contact surface of the rear end of the handle 5. This is achieved by rotating the plug main body 35 until the screw 20 and the contact surface 30 inside the peripheral wall portion 37 of the bottom plug 10 come into contact with each other and screwing the screw rod 32 into the screw hole 21. At this time, the stopper main body 35 rotates while the concave and convex portions 23 and 33 come into contact with each other when the contact surfaces 20 and 30 thereof approach each other, but at least the concave and convex portion 33 of the butt plug 10 has flexibility. Therefore (both the uneven portions 23 and 33 may have flexibility), the flexible uneven portion 33 is deformed and gradually engages deeply while avoiding the uneven portion 23. Then, when the contact surfaces 20 and 30 come into contact with each other, the stopper main body 35 is prevented from rotating, whereby the tail stopper 10 is attached to the handle 5.

  The contact surface 20 of the handle 5 and the contact surface 30 of the butt plug 10 have an inclination that rises forward of the fishing rod with respect to the longitudinal axis O of the fishing rod 1, and are inclined and opposed in a common direction. However, since the contact surfaces 20 and 30 are in contact with each other while deforming, the inclination angles θ of the contact surfaces 20 and 30 are the same, or the contact surface 30 on the bottom plug 10 side is the same. It is preferable that the inclination angle of the direction is shallower than the contact surface 20 on the handle 5 side.

  As described above, according to the present embodiment, the contact surfaces 20 and 30 of the fishing rod 1 and the bottom plug 10 are inclined with respect to the surface perpendicular to the longitudinal axis O of the fishing rod 1. , 30 increases the contact portion (contact area) between the fishing rod 1 and the bottom plug 10 (compared to the case of Patent Document 1 in which the contact surface of the fishing rod and the bottom plug is parallel to the plane perpendicular to the longitudinal axis of the fishing rod). The bottom plug 10 screwed on the fishing rod 1 is difficult to turn (a sufficient rotation stop by the contact surfaces 20, 30 can be secured). Therefore, loosening of the bottom plug 10 is prevented, and dust does not easily enter. Moreover, when the unevenness is engaged, it is difficult to loosen even if water enters.

  In this embodiment, when the screw rod 32 of the bottom plug 10 is screwed into the screw hole 21 of the fishing rod 1, the screw rod 32 moves about the longitudinal axis O while moving in the direction of the longitudinal axis O together with the bottom plug 10. In addition, since the contact surfaces 20 and 30 of the fishing rod 1 and the bottom plug 1 are both arranged around the longitudinal axis O of the fishing rod 1 and abut against each other, they are centered on the longitudinal axis O of the fishing rod 1. It is possible to effectively prevent the rotation of the contact surfaces 20 and 30 with the rotation of the bottom plug 10. Moreover, in this embodiment, since the unevenness | corrugation parts 23 and 33 for rotation prevention are provided in the contact surface 2 and 30 of the fishing rod 1 and the bottom plug 10, the unevenness | corrugation of the contact surface 20 and 30 is the degree of the other party. It is possible to effectively prevent rotation of the bottom plug 10 by strongly hitting the contact surface. Furthermore, in this embodiment, since the contact surface 30 of the bottom plug 10 is formed of a material that bends when the bottom plug is screwed to the fishing rod (the handle 5 side may also be formed as such), When the stopper 10 is screwed, it is pressed against the contact surface 20 in a state where the contact surface 30 is distorted (to be pressed against each other), and thus the rotation of the bottom plug 10 can be effectively prevented.

  5 to 7 show a second embodiment of the present invention. As shown in the figure, the fishing rod 1A of the present embodiment is in the form of a swing rod in which a plurality of rods 2 are sequentially stored, and a tail plug 10A is provided on the screw portion 51 on the outer periphery of the rear end of the main rod 2a. It is screwed and attached to fit.

  An inclined surface 50 is provided at the rear end of the main shaft 2a as a contact surface every time it falls from the outside to the inside. The inclined surface (the contact surface) 50 is cut at the rear edge. A notch-shaped recess 53 is provided.

  The cap-shaped plug body 63 of the bottom plug 10A is made of metal, and a contact member 70 made of a flexible material such as rubber or synthetic resin is attached to the inner bottom portion. The contact member 70 includes an inclined contact surface 75 that comes into contact with the inclined surface (angle contact surface) 5 at the rear end of the main rod 2a, a fitting portion 71 that fits inside the main rod 2a, And an engaging protrusion 72 that engages with the recess 53 of the flange 2a.

  Further, both contact surfaces 50 and 75 are directed toward the rear end portion of the fishing rod 1 with respect to the longitudinal axis O and away from the longitudinal axis O, and with respect to the surface perpendicular to the longitudinal axis O of the fishing rod 1. Are inclined toward the rear end side of the fishing rod (a predetermined angle θ with respect to the longitudinal axis O) and are arranged around the longitudinal axis O of the fishing rod 1.

  In such a configuration, when the end plug 10A is screwed to the outer periphery of the rear end portion of the main rod 2a, the contact surface 75 of the contact member 70 is placed on the inclined surface (the contact surface) 50 of the rear end portion of the main shaft 2a. Abutting while deforming, the engaging projection 72 is engaged with the recess 53 of the main shaft 2a while being deformed to prevent the bottom plug 10A from loosening.
