Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a spinning reel, and more particularly to a forward / reverse rotation mechanism for rotating bodies.

[0002]

2. Description of the Related Art Generally, a rotating body can rotate forward and backward,
Moreover, spinning reels having a reverse rotation prevention function are widely known. With such spinning reels,
It is equipped with its own one-way clutch mechanism, and this one-way clutch mechanism switches between the forward and reverse rotatable state of the rotating body and the reverse rotation blocking state (utility model registration number No. 3005456, utility model registration number). No. 300644
issue).

[0003]

However, in the conventional one-way clutch mechanism used in the spinning reel, the rotating member is inserted inside the clutch and the rotating member rotates. There is a problem in that a gap corresponding to the amount of rotation is formed inside the clutch, and dust enters, causing malfunction. In addition, the one-way clutch mechanism uses a unique one-way clutch, which causes a problem of high cost.

The present invention has been made in view of the above problems, and an object of the present invention is to provide a spinning reel which can reduce the cost by using a ready-made one-way clutch. .

[0005]

The present invention provides a spinning reel comprising a main body, a tube shaft rotatably provided on the main body, and a rotating body fixed to the tube shaft. A possible anti-lever cam shaft, an operating member that is provided on the anti-lever cam shaft and that rotates the anti-lever cam shaft, a boss portion formed on the anti-lever cam shaft, and a boss provided on the main body. And a slider with which the boss is engaged, a one-way clutch that is provided on the pipe shaft and regulates the rotation direction of the pipe shaft, and a switch member for the one-way clutch that is formed on the slider. ON-OFF
And an actuating part for switching; the slider is
The slider is movably provided in a direction orthogonal to the axial direction of the tube shaft; and the slider is rotatably provided around a rotation center of the tube shaft.

[0006]

When the rotating body is switched between the forward / reverse rotation state and the reverse rotation prevention state, the operation member is operated to rotate the anti-lever cam shaft, and the slider is moved in the axial direction of the tube shaft through the boss portion. Move in the direction orthogonal to or rotate around the axis of rotation of the tube axis. As a result, the position where the inclined surface formed on the slider presses the switch member of the one-way clutch changes, and the one-way clutch is switched on and off.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described below with reference to the accompanying drawings. FIG. 1 is a sectional view of a spinning reel according to the present invention. In the figure, reference numeral 1 is a main body, a pipe shaft 2 is rotatably provided in the main body 1, and a spool shaft 3 is provided in the pipe shaft 2 so as to be movable in the axial direction. A spool 4 is fixed to the tip of the spool shaft 3. A rotating body 5 is fixed to the tube shaft 2, and the rotating body 5 is configured to rotate with the rotation of the tube shaft 2. Further, an anti-lever cam shaft 6 is rotatably provided on the main body 1, and an anti-lever 7 is fixed to one end of the anti-lever cam shaft 6 with a screw 8. Further, a boss portion 6a is eccentrically formed on the other end of the anti-lever cam shaft 6.

FIG. 2 is a view taken along the line II-II in FIG. Slider holders 1a, 1a are formed on both sides of the main body 1,
A slider 9 is provided on the slider holders 1a and 1a so as to be movable in the vertical direction in the figure. A guide groove 9a is formed in the slider 9, and the boss portion 6a is movably inserted while being guided by the guide groove 9a.

Further, in FIG. 1, on the outer circumference of the tube shaft 2,
A one-way clutch 10 that restricts the rotation direction of the tube shaft 2 is provided, and the one-way clutch 10 is fixed to the main body 1 (see FIG. 4). The switch member 10a of the one-way clutch 10 has an inclined surface 9 formed on the slider 9.
b and 9b are in contact with each other, and when the slider 9 moves in the vertical direction in the figure, the switch member 10a moves in the horizontal direction in the figure. The one-way clutch 10 used in the present invention is disclosed in JP-A-3-746.
The clutch member disclosed in No. 41, which is generally commercially available, is used.

The operation of the spinning reel thus constructed will be described below. FIG. 2 shows a state in which the tube shaft 2 can rotate only in the direction of the arrow (normal direction).
In order to make the normal and reverse rotation possible from this state, first, by rotating the anti-lever 7 and rotating the anti-lever cam shaft 6, the boss portion 6a is eccentrically rotated. Therefore, the boss portion 6a moves along the guide groove 9a of the slider 9, and the slider 9 moves downward in FIG. 2 in accordance with the eccentric rotation of the boss portion 6a (FIG. 3). Here, in FIG.
When the slider 9 moves downward, the inclined surface 9 of the slider 9
The switch member 10a moves to the left in FIG. 1 along b.
The one-way clutch 10 is switched, and the one-way clutch 10 allows the tube shaft 2 to rotate in the forward and reverse directions.

In order to change the state in which the forward / reverse rotation is possible to the reverse rotation prevention state, the slider 9 is moved upward in FIG. Reverse movement of the tube shaft 2 is restricted by moving the switch member 10a of the clutch 10 to the right in FIG.

FIG. 5 is a side sectional view of another embodiment of the spinning reel according to the present invention, and FIG. 6 is a view taken along the line VI-VI in FIG. The same members as those in the above-described embodiment are denoted by the same reference numerals, and detailed description thereof will be omitted.

In this embodiment, in FIG. 6, a ring-shaped slider 21 is rotatably provided on the slider holding portions 1a, 1a, and the inclined portion 21 is provided at an appropriate position of the slider 21.
a and 21a are formed, and a projection 21b is formed continuously with the inclined portion 21a. Further, the slider 21 has a guide groove 21c formed therein.
The boss portion 6a of the anti-lever cam shaft 6 is inserted in the.

When the anti-lever cam shaft 6 is rotated, the slider 21 rotates clockwise in FIG. 6, and the protrusion 21b presses the switch member 10a by the rotation of the slider 21 so that the slider 21 can be rotated forward and backward. (Fig. 7).

When changing from the forward / reverse rotatable state to the reverse inhibition state, the slider 21 is rotated counterclockwise in FIG. 7 by rotating the anti-lever cam shaft 6 in the opposite direction to the above. Reverse movement of the tube shaft 2 is restricted by moving the switch member 10a of the one-way clutch 10 to the state shown in FIG.

[0016]

As described above, the present invention has a structure in which a ready-made one-way clutch can be used. Therefore, it is effective for foreign matter such as dust to enter into the gap corresponding to the rotation amount generated inside the clutch. Can be prevented. Further, although the spinning reel uses a one-way clutch, it can be manufactured at low cost and the cost can be reduced. Further, since the ON / OFF of the one-way clutch is simply switched, the mechanism can be simplified and the assembly and disassembly can be easily performed.
