Description

DETAILED DESCRIPTION OF THE INVENTION The present invention provides a double-bearing reel, more specifically, a spool is rotatably supported between a pair of side frames via a spool shaft, and power generated by rotational operation of a handle is transferred via a drag mechanism. The present invention relates to a double bearing reel which transmits power to the spool and rotates the spool.

Conventionally, as this type of reel, between a pair of side frames,
a drag disk that supports the spool shaft rotatably and displaceably in the axial direction, supports the spool rotatably on the spool shaft, and is disposed at an axial end of the spool shaft and faces seven lunges of the spool; is supported so as to be relatively movable in the axial direction, a drag washer is interposed between the disk and the flange, and a contact plate facing the washer RIC is held on at least one of the flange and the disk. , one of the drag disker or the spool is moved in the axial direction by the displacement of the spool shaft in the axial direction, the contact plate is pressed against the drag washer, and the power from the rotational operation of the handle is transferred from the spool shaft to the drag mechanism. A reel has been proposed in which the free rotation resistance of the spool is adjusted by adjusting the drag force transmitted to the spool via a contact plate and pressed against a drag washer.

However, the contact surfaces between the drag washer and the contact plate in this reel are straight flat surfaces perpendicular to the axis of the spool shaft, and both contact surfaces are in full contact with each other. Therefore, if the amount of displacement of the spool shaft in the axial direction is increased to strengthen the drag force,
Due to this drag force, the flanges of the drag disk and spool are bent in the direction of separation, or one of the pair of side frames is distorted relative to the other, and the outer peripheral portion of the contact surface between the drag washer and the contact plate is distorted. separated and no longer made full contact, and only the center side of the contact surface was in contact. If there is a new partial contact when the drag force is strong, the wear on the center side will be more severe than the wear on the outer circumferential side, which will reduce the friction area and also reduce the maximum drag force with respect to the pressure welding force. be. Furthermore, since the amount of displacement of the spool shaft in the axial direction is small and the contact surfaces are in full contact even when the drag force is weak, there is also the problem that the adjustment range of the drag force is narrow.

The present invention has been made in view of the above-mentioned problems, and an object of the present invention is to provide a double-bearing reel that can reduce uneven wear of the contact surface in a drag mechanism and widen the adjustment range of drag force. Accordingly, the present invention supports a spool shaft between a pair of side frames so as to be rotatable and displaceable in the axial direction,
The spool is rotatably supported on the spool shaft, and
one of the spool and a drag disk facing seven flange of the spool is supported on the spool shaft so as to be relatively movable in the axial direction, and a drag washer is interposed between the disk and the seven flange; A double-bearing reel that holds a contact plate facing the sonosha on at least one of the flange and the disk, the radially outer side of the opposing surface of the drag washer and the contact plate being radially inner, It is characterized by narrowing the distance between the opposing surfaces.

It is also possible to provide an annular lumen in the central part of a) so that the radially inner parts of the contact plates (11), (12) can be received in these lumens. Further, the contact plate may be provided on both the drag disk (8) and the first flange (62), or may be provided on only one of them. In this case, it is preferable to hold the washer (9) on a member that does not hold the contact plate.

In addition, by moving the spool (6) in the axial direction to press the drag washer (9) against the drag disk (8),
Move the drag disk (8) to
9) may be pressed against the first flange (62) of the spool (6). In this case, movement of the spool (6) in the axial direction is prevented.

Moreover, although the drag lever (30) is supported on the second side 7L/-m (2), it may be supported on the first side frame (1).

Further, although the drag lever (80) is used as a means for displacing the spool shaft (5) in the axial direction, the displacing means is not particularly limited.

As described above, in the present invention, the radially outer side of the opposing surface of the drag washer and the contact plate held on at least one of the drag disk or the first flange of the spool,
The distance between the opposing surfaces is narrowed in the radial direction (so,
Compared to the conventional product in which the distance between the opposing surfaces of the drag washer and the contact plate is the same, the drag force can be adjusted over a wider range, and the drag action can be performed smoothly. Said 7
Since the contact plate can be brought into full contact with the drag washer by the deflection of the lunge, the drag force relative to the pressure contact force can be increased, and uneven wear of the drag washer and the contact plate can be reduced.
