Since the autocast inside gear 42 is brought into contact and exited in a state where it is inserted, the autocast inside gear 42 is prevented from returning to its original position.

Since the level wind device according to the present invention has the above-described configuration, its operation will be explained below.

First, when the auto cast lever 1 is pressed downward, the joint 5 connected integrally with it rotates, and when the lever gear 40 is rotated in the same direction, the auto cast gear 26 meshing with the lever gear 40 resists its torsion spring 28. Since the autocast side gear 42 meshing with the autocast gear 26 is rotated in the direction of the arrow about the shaft 36, the autocast side gear 42 is pulled and moved in the direction of the arrow. Accordingly, the third link piece 70 connected to the protrusion 50 of the curved arm 48 of the autocast side gear 42 through the hole 72 is pulled and moved in the same arrow direction.

At this time, the cam portion 74 of the third link piece 70 that is engaged with the long groove 114 of the presser plate 104 is connected to the traverse cam shaft gear 94.
Since the traverse camshaft gear 94 is pushed up via the spring plate 108 of the presser plate 104 disposed below, the camshaft gear 94 and the drive gear 14 are disengaged, so the camshaft gear 94 is in a free state. becomes. At the same time, the third link piece 7 is inserted into the engagement/disengagement notch 86 of the traverse cam shaft bush 84.
As the third link piece 70 moves in the direction of the arrow while the conical part 82 of the spring plate 78 provided in the notch groove 76 of No. 0 is engaged, the traverse camshaft bushing 84 resists the elastic force of the coil spring 88. Rotate. However, when the third link piece 7 is pulled and moved a predetermined distance, the third link piece 7
Since the conical portion 82 of the spring plate 78 of 0 is disengaged, the traverse camshaft bushing 84 is rotated in the opposite direction by the elastic force of the coil spring 88 and returned to its original position.

The rotation of the traverse camshaft bushing 84 is caused by the traverse camshaft outer cylinder 100 which is fitted into the annular portion 96 of the bushing 84.
is transmitted, and this outer cylinder reciprocates together with the bushing 84. That is, when the third link piece 70 is moved in the direction of the arrow shown in FIG. Since it rotates in the direction of arrow A in FIG. 18 via the shaft bush 84, the level wind shaft support portion 134 also tilts in the direction of the arrow. Therefore, the level wind shafts 144, 146 supported by the pair of engagement pins 136 of the support portion are
6.136 is disengaged and opens in a V-shape with the base 24 as the core due to the elastic force of the leaf spring attached to the end.

It is cast smoothly through the process.

Next, the traverse cam shaft outer cylinder 100 rotates in the direction of arrow A' in the opposite direction to that described above by rotating the bushing 84 in the opposite direction to that described above, and returns to its original position, and then the handle 10 is rotated. When the drive gear 14 is rotated, the traverse cam shaft gear 9
4, and as the gear 94 rotates, the traverse cam shaft 98 also rotates, so the engaging pawl 142 of the level wind shaft guide member 128 engages with the cam groove 99 of the traverse cam shaft 98. Therefore, this guide member 128 reciprocates in the horizontal direction along the traverse cam shaft outer cylinder 100 while fitting into it, and in the meantime, the level wind shaft guide member 128 sequentially moves the level wind shafts 144 and 146 which were open in a fan shape. The fishing line 144, 146 is accommodated so as to be clamped by a telescopic engagement pin 136 protruding from the support part 134, and the fishing line 144, 146 can hold the fishing line in a parallel position to each other and let it out smoothly. Said shirt) 144, 146 is connected to a pair of telescopic engagement pins 13.

Also, attached FIG. 23 shows the state in which the outer cylinder 100 is pulled out of the engagement pin 136 by one of the level wind shafts 146 due to the first rotation of the traverse camshaft bushing 84, and attached FIG. 84 returns to its original position by the next rotation in the opposite direction, the level wind shaft guide member 128 slides horizontally on the outer cylinder 100 11
In J, the -level wind shafts 144 and 146 are shown housed between the engagement pins 136 of the support portion 134, respectively.

In the state shown in FIG. 22, the fishing line is smoothly let out while moving horizontally between the pair of level wind shafts 144, 146.

(Effects) The level wind device of the double bearing type fishing reel according to the present invention not only has a simple structure, but also has a level winding device that is fitted onto the outer cylinder of the traverse cam shaft rotatably supported between the reel side plates. The structure is such that a level wind shaft, which is separately provided on a base and can be opened and closed in a fan shape, is engaged and disengaged between a pair of telescopic engagement pins provided on the shaft support portion of the wind shaft guide member. Compared to the case where the engaging pin of the guide section engages and disengages from the notch of the mover, the engaging pin does not come off during thread unwinding, and the level wind shaft can be accommodated and detached between the engaging pins. Since this is carried out in accordance with the rotational movement of the traverse cam shaft outer cylinder, there is no need to provide a complicated guide section as in the conventional example.

Further, there are effects such as engagement and disengagement between the traverse cam shaft gear and the handle drive gear, and rotation of the traverse cam shaft outer cylinder can be carried out efficiently with extremely simple operations.
