Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a motor, and more particularly, to a motor for an electric reel mounted on a reel body of an electric reel for rotating a spool in a line winding direction.

[0002]

2. Description of the Related Art A motor used for an electric reel, particularly a motor mounted in a spool, has a motor body having an opening at a base end and a cap member for closing the opening of the motor body. The motor body has a rotating shaft projecting from both ends, and one end of the rotating shaft projecting is rotatably supported by the cap member. The cap member is fixed to a motor holding unit provided on the reel body. One end of the rotating shaft further protrudes from the cap member, and the motor holding portion is formed in a bottomed cylindrical shape so that one end of the rotating shaft can be stored therein. A roller clutch (an example of a one-way clutch) for inhibiting rotation of the motor in the line feeding direction is mounted between the motor holding portion and one end of the rotating shaft.

[0003] The roller clutch has an outer ring non-rotatably mounted on the motor holding portion, and a plurality of rollers mounted between the outer ring and the rotating shaft. The plurality of rollers are arranged at intervals in the circumferential direction by the retainer.

[0004]

In the above-mentioned conventional configuration,
Since a roller clutch is provided at one end of the rotating shaft protruding from the motor to prevent rotation of the rotating shaft in the line feeding direction, the length of the rotating shaft of the motor becomes longer. As described above, when the rotating shaft that does not contribute to the output of the motor is long, the output of the motor is limited to a small value when the size of the reel is prioritized, and the width of the reel is widened when the output of the motor is prioritized. .

An object of the present invention is to reduce the length of a rotating shaft as much as possible in a motor of an electric reel in which rotation of the rotating shaft in a line feeding direction is prohibited.

[0006]

A motor for an electric reel according to a first aspect of the present invention is a motor mounted on a reel body of the electric reel for rotating a spool in a line winding direction. And The motor body has a bottomed cylindrical case member having an opening at the base end, a cap member fixed to the base end of the case member to close the opening, and a case member and a cap member which are arranged to protrude from the tip of the case member. It has a rotating shaft rotatably mounted. The one-way clutch is a clutch that is disposed between the case member or the cap member and the rotation shaft, and that allows the rotation shaft to rotate in the yarn winding direction and prohibits rotation in the yarn unwinding direction.

In this motor, rotation of the rotating shaft in the line payout direction is prohibited by a one-way clutch mounted between the case member or the cap member and the rotating shaft. Therefore, it is not necessary to project one end of the rotating shaft outward from the cap member in order to mount the one-way clutch as in the related art, and the length of the rotating shaft can be reduced. Therefore, when priority is given to the dimensions of the reel, the output of the motor can be increased, and when priority is given to the output of the motor, the lateral width of the reel can be reduced.

A motor for an electric reel according to a second aspect of the present invention is the motor according to the first aspect, wherein the cap member has a through hole in which a rotation shaft is disposed at the center, and the one-way clutch is
It is mounted between the inner peripheral surface of the through hole and the rotating shaft. In this case, since the one-way clutch is mounted in the through hole provided in the cap member, the one-way clutch can be easily mounted.

A motor for an electric reel according to a third aspect of the present invention is the motor according to the second aspect, wherein the one-way clutch is provided so as to be circumferentially spaced from an outer ring which is non-rotatably mounted in a through hole of the cap member. And a plurality of rollers formed so as to be curved outward and separated from each other, and a plurality of rollers that are rotatably mounted on the cam between the rotating shaft and the outer ring and that can bite into the outer ring. In this case, the motor has a simple structure by a roller type one-way clutch in which the inner ring is shared with the rotating shaft.

A motor for an electric reel according to a fourth aspect of the present invention is the motor according to the second aspect, wherein the one-way clutch comprises an outer ring non-rotatably mounted in a through hole of the cap member, and a rotating shaft rotatable on the inner peripheral side of the outer ring. Between the inner ring, the inner ring and the outer ring, and a plurality of cam parts which are formed on the inner peripheral surface of the outer ring or the outer peripheral surface of the inner ring so as to be circumferentially spaced and curved outward or inward. And a plurality of rollers which are rotatably mounted on the cam portion and can bite into the outer ring or the inner ring. In this case, since the diameter of the one-way clutch is increased by the amount of the inner ring, the capacity of the one-way clutch is increased.

A motor for an electric reel according to a fifth aspect of the present invention is the motor according to any one of the first to fourth aspects, wherein the one-way clutch has a holding member for holding the rollers at intervals in a circumferential direction. In this case, since the rollers are held by the holding member at intervals in the circumferential direction, the operation of the one-way clutch becomes smooth.

A motor for an electric reel according to a sixth aspect of the present invention is the motor according to any one of the first to fifth aspects, wherein the one-way clutch has an urging member for urging the roller in a direction to bite into the outer ring or the inner ring. In this case, since the roller is urged in the biting direction, when the motor attempts to rotate in the line feeding direction, the roller immediately bites into the outer ring or the inner ring, and the rotation is prohibited.

A motor for an electric reel according to a seventh aspect of the present invention is the motor according to any of the second to sixth aspects, wherein the rotating shaft is rotatably mounted on the cap member via a bearing. In this case, since the rotating shaft is supported by the bearing on the cap member on which the one-way clutch is mounted, vibration of the rotating shaft during driving of the motor is reduced.

According to an eighth aspect of the present invention, in the motor for the electric reel according to the seventh aspect, the bearing is disposed adjacent to the inside of the one-way clutch. In this case, since the bearing is arranged adjacent to the inside of the one-way clutch, it is possible to suppress an increase in the length of the rotating shaft even if the bearing is provided.
