The support wall 9 is a plate-shaped member having a flat surface in the radial direction orthogonal to the spool shaft C2, and has a tube portion through which the carrier main body 81 of the carrier 8 passes through the center. Have A bearing 93 is provided between this cylinder part and the carrier main body 81, and the support wall 9 fixed to the bobbin trunk part 32 of the carrier 8 and the spool 3 can rotate relatively. It is supposed to be done. Here, the support wall 9 corresponds to a part of the spool 3 from being integrally provided with the string winding trunk portion 32 of the spool 3.

On the base end surface of the support wall 9 on the spool 3 side, a pair of rotation stop convex portions 91 projecting toward the spool 3 side so as to engage with a pair of rotation stop recesses 74 to be described later. (2nd engagement uneven part) is provided. The rotation stop convex part 91 forms the flat convex surface of the direction orthogonal to the radial direction of the spool rotation shaft 31 toward the spool rotation shaft 31 side, and interposes the spool rotation shaft 31 in the said radial direction. It is installed in two places facing each other.

The ring gear 73 is provided on the same shaft as the spool rotation shaft 31 and has an inner gear 731 which engages three planetary gears 72A, 72B, and 72C on the ring inner circumferential surface. The planetary gears 72A, 72B, and 72C each rotate around the inner gear 731 while rotating by the rotation of the sun gear 71.

The ring gear 73 is fitted to the inner circumferential surface of the locking cylinder 34 of the spool 3 in an unrotable state. The ring gear 73 has a rotation stop recess 74 (first engagement concave-convex portion) formed by notching a part of the circumferential direction at the outer circumferential portion facing the support wall 9. The rotation stop recess 74 forms a notch surface in a direction orthogonal to the radial direction of the ring gear 73 in a state facing the outer circumferential side, and faces the radial direction of the ring gear 73 at the outer circumferential edge. It is installed in two places.

The engagement concave-convex portions (rotation stop convex 91, rotation stop concave 74) which protrude or concave in each of the ring gear 73 and the support wall 9 in the direction of the spool rotation axis 31 in this way. ) And engaging each other restricts the rotation of the ring gear 73 relative to the support wall 9, the flange portion 33 of the spool 3 and the bobbin trunk 32.

Thus, in this 2nd Embodiment, in each simple structure which protrudes in the direction of the spool rotation axis 31, or concave, the concave-convex part which formed the concave ring gear 73 and the spool 3 in the direction is formed, The rotation of the ring gear 73 relative to the spool 3 can be regulated by this.

In addition, by engaging both engagement concave-convex portions (rotation stop convex portion 91, rotation stop concave portion 74) with each other, it is possible to prevent deformation due to complicated processing or indentation on the inner circumferential surface of the spool 3. And the deterioration of the quality can be suppressed.

As mentioned above, although embodiment of this invention was described, these embodiment is shown as an example and is not intending limiting the range of invention. The embodiment can be implemented in various other forms, and various omissions, substitutions, and changes can be made without departing from the gist of the invention. Embodiments and modifications thereof include, for example, those that can be easily assumed by those skilled in the art, substantially the same ones, and equivalent ranges.

For example, in the said embodiment, although the 1st engagement uneven part and the 2nd engagement uneven part were provided in two places in the circumferential direction around the motor rotation shaft 41 or the spool rotation shaft 31, respectively, 2 It does not restrict | limit to being a location, It may be three or more places or one place.

In addition, in this embodiment, although the ring gear side is a concave part and the member side normally forms the convex part, the concave-convex may be reversed, respectively. In other words, even when the ring gear side is a convex portion and the ordinary member side is a concave portion, the rotation of the ring gear can be restricted with respect to the normal member.
