JP 2003-235410 A (paragraph number [0018] and FIG. 1 and FIG. 2)

Together with the drive nut and the locking nut, it is screwed into the same male threaded portion carved in the seat base.
If this happens, if the drive nut comes into contact with the hand and the drive nut is loosened, it is possible that the hand will also touch the locking nut that is placed in contact with the drive nut, and both rotate in the same direction. Thus, it can be considered that the drive nut is separated from the reel leg.
For this reason, an event may occur in which the reels rattle during fishing, and the comfort is remarkably impaired.

  An object of the present invention is to provide a reel seat structure that can effectively prevent loosening of a drive nut and that can perform comfortable fishing in a structure including a locking nut.

〔Constitution〕
According to a first aspect of the present invention, there is provided a drive male screw portion into which the drive nut is screwed to a seat base on which the movable hood is mounted, and a locking male screw portion to which the locking nut is screwed. The screw groove of the drive male screw part and the screw groove of the loosening-preventing male screw part are formed in spiral grooves that are opposite to each other in the left-right direction.

[Action]
The screw groove of the drive male screw part and the screw groove of the loosening-preventing male screw part are formed as spiral grooves in opposite directions. As a result, when the drive nut tries to rotate toward the loosening side, it rotates along the spiral groove and moves to the side of the locking nut. Trying to move around in the same direction.
However, if the locking nut rotates in the same direction as the drive nut, the locking nut will move in the direction closer to the drive nut, and the drive nut and the locking nut will push strongly against each other. The nut is prevented from rotating.

〔effect〕
Therefore, it is possible to provide a locking nut with a higher locking effect compared to the conventional one only by modifying the screw groove for screwing the drive nut and the locking nut to advance in opposite directions. It came.

  A characteristic configuration of the invention according to claim 2 is that, in the invention according to claim 1, the outer diameter of the thread of the locking male screw portion is smaller than the screw bottom diameter of the driving male screw portion. The operational effects are as follows.

[Function and effect]
With this configuration, even if the screw groove direction of the screw thread of the locking male screw part and the screw groove direction of the driving male screw part are set in opposite directions, the drive nut is driven in the state of passing through the male screw part. It can be screwed into the male threaded portion, and can be made to correspond to a configuration in which the drive nut must be disposed on the side close to the movable hood.

  The characteristic configuration of the invention according to claim 3 is that the invention according to claim 1 or 2 is the fishing rod provided with the reel seat according to claim 1 or 2, and the function and effect thereof are as follows.

[Function and effect]
Since the reel leg holding ability of the movable hood could be increased, it was possible to provide a fishing rod that can concentrate on the fishing operation without paying attention to the reel coming off.

  The fishing rod A used for a boat rod etc. is demonstrated. As shown in FIG. 1, a fishing rod A is configured with a front grip 2, a reel seat 3, a rear grip 4, and a bottom plug 5 on the hand side of the rod material 1.

The configuration of the reel sheet 3 will be described. As shown in FIGS. 1 and 2, the reel sheet 3 includes a sheet base 3 </ b> A fixed to the bag material 1, a fixed hood 3 </ b> B integrally formed at one end of the sheet base 3 </ b> A in the hook axis direction, and a fixed hood 3 </ b> B. It is composed of a movable hood 3C provided in an opposing state.
A reel mounting surface 3a on which the reel leg B is mounted is formed between the fixed hood 3B and the movable hood 3C in the seat base 3A.

  As shown in FIGS. 1 and 2, the movable hood 3 </ b> C has a protrusion that engages with an engagement groove (not shown), and is slidable along the engagement groove in the axial direction. A drive nut 6 for slidingly driving the movable hood 3C is provided on the tip side of the movable hood 3C, a locking nut 7 is provided on the tip side of the drive nut 6, and a nut mechanism N is constituted by both nuts 6 and 7. It is.

  The attachment structure of the drive nut 6 and the locking nut 7 will be described. As shown in FIGS. 1 and 2, the cylindrical portion extends from the movable hood 3C mounting portion of the seat base 3A toward the side opposite to the side where the fixed hood 3B exists, and is driven to the outer peripheral surface of the cylindrical portion. A male screw portion 3b is formed. A drive nut 6 that drives the movable hood 3C is screwed into the drive male screw portion 3b.

As shown in FIGS. 1 and 2, a screw portion having a smaller diameter than the drive male screw portion 3b is formed on the side of the drive male screw portion 3b opposite to the fixed hood presence side, and the screw portion having the small diameter is loosened. A locking male screw portion 3c is formed, and a locking nut 7 is screwed onto the locking male screw portion 3c.
The relationship between the drive male screw portion 3b and the locking male screw portion 3c is, for example, as shown in FIG. 2B, if the driving male screw portion 3b is a right screw, the locking male screw portion 3c is a left screw. As described above, the screw groove of the drive male screw portion 3b and the screw groove of the locking male screw portion 3c are formed in spiral grooves that are opposite to each other in the left-right direction.

As described above, since the screw groove of the drive male screw portion 3b and the screw groove of the locking male screw portion 3c are formed in spiral grooves that are opposite to each other in the left-right direction, the drive screwed into the drive male screw portion 3b is driven. When the locking nut 7 that is screwed into the locking male screw portion 3c is provided in contact with the nut 6, the driving nut 6 is loosened and is pressed against the locking nut 7 to come into contact with the locking nut 7. Even if it is intended to rotate the contact 7, the locking nut 7 that tries to rotate in the same direction as the rotation of the drive nut 6 moves to the drive nut 6 side due to the rotation. Will be increased.
Eventually, a force that prevents the drive nut 6 from loosening is applied by the loosening prevention nut 7.

As shown in FIG. 2, the relationship between the size of the drive male screw portion 3b and the locking male screw portion 3c provided on the seat base 3A is that the bottom diameter D of the screw groove formed in the drive male screw portion 3b is It is formed to have a diameter larger than the outer diameter d of the screw thread of the locking male screw portion 3c.
With such a configuration, when the drive nut 6 is screwed into the drive male screw portion 3b, the lock-off male screw portion 3c can be passed without being caught by the lock-off male screw portion 3c.

As shown in FIG. 2, the drive male screw portion 3b and the locking male screw portion 3c may be composed of the same type of screw, but as shown in FIG. 3, the drive male screw portion 3b is a square screw, The loosening-preventing male screw portion 3c may adopt an arbitrary screw form such as a triangular screw.
With such a configuration, the drive male screw portion 3b that receives the load directly from the reel legs can adopt a square screw type with high thread strength, and the looseness-preventing male screw portion 3c that only exhibits a locking function. Adopted the triangular screw type.
