Description

[Detailed description of the device]

[0001]

[Industrial applications]

 According to the present invention, a rotary frame having a bail arm and a spool that reciprocates in the axial direction of the rotary frame in association with the rotation of the rotary frame are provided. The present invention relates to a spinning reel equipped with a thread drop prevention device for preventing the thread from coming off.

[0002]

[Prior art]

 In this type of spinning reel, the yarn wound around the yarn accommodating portion of the spool may be relaxed by its elastic restoring force to expand the winding diameter. Then, the loosened thread protrudes from the thread accommodating portion, goes over the rear end wall, enters the axis of the rotary frame, and winds around the support shaft located at the axis, or around other parts. , In the end, it sometimes caused thread breakage. In particular, when the winding speed of the yarn becomes slow, or when the reel is made compact and the wall thickness (front-back length) of the spool rear end wall is made small, the yarn easily comes out of the yarn accommodating portion. In view of this, there is a conventional device disclosed in Japanese Utility Model Laid-Open No. 63-55870 as a device provided with a preventive device that acts on a yarn passing over the rear end wall of the spool to prevent the yarn from falling. Is like this: In other words, a support shaft of the rotating frame that supports the bail arm is installed along the longitudinal direction of this support arm (spool movement direction), and a roller is loosely fitted to this support shaft to support this roller. It was configured to be rotatable around its axis and slidable in the axial direction of the support shaft. On the other hand, an annular groove is formed on the rear end wall of the spool, and the roller is engaged with the annular groove, so that the roller is moved around the spool as the rotary frame rotates and the roller is supported around the spindle. While rotating, the roller is reciprocally moved integrally with the spool in the axial direction to prevent the thread, which is pulled out from the thread accommodating section by the roller, from entering the axial center side.

[0003]

In the case of such a conventional structure, the roller moving in the axial direction together with the spool engages with an annular groove or the like formed in the rear end wall of the spool to rotate around the spool axial center. Since it is located on the outside of the spool so that it can be rotated to the right, it is susceptible to the environment of the fishing site, and especially when throwing fishing on the coast, sea breeze, sea sand, etc. attach to the roller part. In some cases, the rotation movement of the roller may not be smooth. On the other hand, for example, as disclosed in Japanese Utility Model Laid-Open No. 60-106466, a tubular portion is extended forward from a flange portion which is locked to a supporting arm of a rotary frame and which prevents a yarn drop. A disk portion as a bottom surface was formed at the front end of the disk, and a base end boss portion externally fitted to the spool shaft was formed at the center position of the disk surface. Since the base end boss portion that rotates relative to the spool shaft is located inside the spool, it is isolated from the sea breeze and is unlikely to be affected by them. However, the two parts of the flange are notched, and the notches are engaged with the support arm to rotate the thread drop prevention device integrally with the rotating frame. If the space between the inner surface of the part and the outer surface of the support arm is too small, foreign matter such as sea sand and salt will be caught in the space, and the relative sliding movement of the thread drop prevention device with respect to the support arm will be smooth. On the other hand, if the gap is set too large, the support arm will impact the inner surface of the notch by that amount when the rotation of the rotary frame is started. During long-term use, the internal surface of the notch will sag due to collision, so it was necessary to take measures such as increasing the internal pressure of the internal surface. An object of the present invention is to provide a device in which the conventional drawbacks can be solved by rationalizing the portion of the thread drop prevention device that is integrally rotated with the rotary frame and relatively slid in the axial direction. There is a point to do.

[0004]

[Means for Solving the Problems]

 According to a characteristic configuration of the first invention, the thread drop prevention device is supported so as to be rotatable about the shaft axis with respect to the spool shaft and to move in the axial direction in cooperation with the spool shaft. At the same time, the driven member formed on the yarn drop prevention tool is brought into contact with a member that rotates integrally with the rotation frame at the internal position of the spool, and the rotation frame and the thread fall prevention tool rotate together. It is configured as follows, and its effects are as follows.

[0005]

[Action]

 In other words, the driven member formed on the thread drop prevention device contacts the member that rotates integrally with the rotary frame, receives the driving force of the rotary frame, and rotates the thread drop prevention device integrally with the rotary frame. When the fall prevention tool moves in cooperation with the spool shaft, the driven member slides relative to the member that rotates integrally with the rotary frame. Then, the driven member and the member that rotates integrally with the rotating frame maintain the state of being positioned inside the spool, and perform integrated rotation and relative sliding.

[0006]

[Effect of device]

 Therefore, it is not necessary to consider the adhesion of sea sand, seawater, etc. between the driven member and the member that rotates integrally with the rotating frame, and there is a large gap between the driven member and the member that rotates integrally with the rotating frame. No gap is required, and the impact force that the driven member receives from the member that rotates integrally with the rotating frame is small, and defects such as sagging can be suppressed.

[0007]

[Means for Solving the Problems]

 A characteristic configuration of the second invention is that the driven member cooperates with the spool shaft to be slidable in an axial direction thereof, and a base end portion loosely fitted around the axial center so as to be relatively rotatable, It is extended so as to engage with an engaging groove formed in a member that rotates integrally with the rotating frame, and the operation and effect thereof are as follows.

[0008]

[Action]

 In other words, the driven member engages with the engaging groove of the member that rotates integrally with the rotating frame, receives the driving force of the rotating frame, rotates the yarn drop prevention device integrally with the rotating frame, and prevents the yarn drop. When the tool moves in cooperation with the spool shaft, the driven member slides relative to the member that rotates integrally with the rotating frame. The driven member and the member that rotates integrally with the rotating frame maintain the state of being positioned inside the spool, and perform integral rotation and relative sliding.

[0009]

[Effect of device]

 As a result, the driven member can be engaged without forming a large gap in the engaging groove of the member that rotates integrally with the rotating frame, and it is possible to suppress the occurrence of sagging or the like on the inner surface of the engaging groove.

[0010]
