An opening a that connects the space 13A to the outer space is formed on the wall surface of the wall surface located on the spool 4 side, and a cover thin plate 20 that covers the opening a is provided.

Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a spinning reel in which a pair of support arms for supporting a bail are formed on a rotary frame that is rotated to wind a thread on a spool.

[0002]

[Prior art]

 For spinning reels, the rotating frame has been made lighter so that the handle operation is lightened so that the thread can be taken up lightly. As such, there is provided a space for accommodating other components or a space mainly for reducing the weight within the thickness of the support arm (for example, Japanese Utility Model Laid-Open No. 54-182394).

[0003]

[Problems to be solved by the device]

 This will certainly reduce the weight, but in order to make the weight more effective, the wall that forms the space should be made as thin as possible so that the space within the wall is large. Is desirable. However, there is a limit to reducing the wall thickness, and especially when the support arm is die-cast, if the wall thickness is too thin, the molten metal flow in that part was poor and satisfactory molding could not be achieved. . An object of the present invention is to provide a material that can be easily molded by making a device for forming a wall thickness and can achieve weight reduction by thinning.

[0004]

[Means for Solving the Problems]

 A feature of the present invention is that a pair of support arms for supporting a bail are formed on a rotating frame that is rotated to wind a thread on a spool, and a space penetrating between opposing wall surfaces of at least one of the support arms. And a cover thin plate that covers the opening of this space is attached, and the action and effect are as follows.

[0005]

[Action]

 As a means of reducing the wall thickness, it is possible to reduce the wall weight by removing the wall thickness portion and penetrating it into the space instead of forming the thin portion integrally with other portions. However, it is possible to reduce the weight, but at the same time, by removing the thick wall portion, the strength is weaker than that with the wall, so that the cover thin plate covers the opening of the penetration part. By attaching the cover thin plate, the cover thin plate exerts a reinforcing effect, and since the cover thin plate is a component independent of the support arm, it can be easily thinned.

[0006]

[Effect of device]

 Therefore, it is possible to obtain the same effect as in the state where the wall thickness is made thin, and thereby, it is possible to achieve the weight reduction, and the supporting arm can be easily manufactured without lowering the strength.

【Example】

 As shown in Fig. 1, a spool shaft 3 is cantilevered in front of a reel body 2 having a leg portion 1 for attaching to a rod, and a spool 4 is attached to the spool shaft 3 to form a reel. Inside the main body 2, the cylinder shaft 5 is loosely fitted to the spool shaft 3, the rotary frame 6 is integrally rotatably attached to the cylinder shaft 5, the input pinion 7 is formed, and the input pinion 7 is driven. By engaging the gear 8 and operating the handle 9, the rotary frame 6 is rotationally driven via the drive gear 8, the input pin-on 7, and the cylinder shaft 5. On the other hand, a spiral shaft 10 is installed in parallel with the spool shaft 3, and a transmission gear 11 is provided at one end of the spiral shaft 10 to drive the screw shaft 10 by engaging the input pin-on 7 and the transmission gear 11 with each other. An oscillating mechanism A that moves the rotating frame 4 back and forth with the rotation of the rotating frame 6 is formed to form a spinning reel.

The structure of the reel unit will be described. As shown in FIG. 1, a lightening space B is formed in the rear surface of the leg portion 1 so as to be recessed forward, and a bearing that pivotally supports the shaft end of the spiral shaft 10 on the rear wall 2A of the reel body 2. The mounting through-hole 2B for the is formed. A lid 12 for closing the space B and the through hole 2B is provided to cover the space. The lid 12 is provided with a function as a name plate clearly specifying the specifications and the like.

The support arms 13, 13 of the rotating frame 6 will be described. As shown in FIG. 1, an arm cam 15 having a yarn guide roller 14 is attached to one supporting arm 13, and a swing arm 16 is attached to the other supporting arm 13, and the arm cam 15 and the swing arm 16 are attached. A veil 17 is laid across. As shown in FIG. 2 and FIG. 4, both support arms 13 and 13 are die cast using aluminum material, and at the same time, spaces 13A and 13A are formed in the support arms 13 and 13 and the arm cam 15 is attached. The space 13A of the support arm 13 accommodates a biasing mechanism 18 for maintaining the switched state while allowing the yarn winding state of the bail 17 and the posture corresponding to the yarn unwinding. In the space 13A of the support arm 13 to which the arm cam 15 is attached, the wall surface portion located on the side opposite to the side where the spool 4 is present is opened, and a decorative cover body 19 is provided at this open portion to close it. An opening a is formed in a wall surface portion of the spool 4 on the side facing the decorative cover body 19, so that the wall surface on the side of the spool 4 and the wall surface facing the spool 4 are in a penetrating state in the space 13A. An aluminum cover thin plate 20 for covering the opening a on the space side is provided, and dovetail-shaped guide portions 13a, 13a are formed near the left and right ends inside the wall surface on which the opening a is formed. The opening a can be closed by inserting the cover thin plate 20 along the guide portions 13a, 13a. To fix the cover thin plate 20 in the closed state, a resin intermediate cover 21 is interposed, and a metal cover 22 is further covered from the outside to fix the base arm of the support arm 13 with a screw. Fix it. A balance weight 23 is provided on the inner surface of the intermediate cover 21 to improve the rotation balance of the rotary frame 6. Further, another balance weight 23 is attached to the base end portion of the support arm 13. On the other hand, as shown in FIG. 3, a space 13A is formed inside the support arm 13 that pivotally supports the swing arm 16, and also in this space 13A, the wall surface portion located on the side opposite to the side where the spool 4 is present. In the open state, a decorative cover body 24 is provided to close the open portion, and an opening a is formed in the wall surface portion on the spool 4 existing side facing the decorative cover body 24 to form a spool 4 in the space 13A. The wall surface on the existing side and the wall surface opposite thereto are in a penetrating state. However, in this support arm 13, there is no cover such as the cover thin plate 20, and the space 13A is open toward the spool 4.

[Other Embodiments] It is sufficient for any one of the support arms 13 to form the opening a on the wall surface of the support arm 13 facing the spool side. The cover thin plate 20 may be attached to the openings a of both the support arms 13, 13. The opening a may be formed in the side wall of the support arm 13.

It should be noted that reference numerals are added to the claims of the utility model for convenience of comparison with the drawings, but the invention is not limited to the configurations of the accompanying drawings by the entry.
