  However, when the cylindrical portion of the drive gear and the shaft member are integrally fixed by a fixing member such as a pin, not only the number of parts is increased by the fixing member such as a pin or a screw, but also such a fixing member. It is necessary to add a processing step such as forming a radial hole for inserting a hole in both the cylindrical portion and the shaft member, and the manufacturing cost increases.

  In addition, it is necessary to align the radial holes formed in both the cylindrical portion of the drive gear and the shaft member, and it is necessary to insert a fixing member such as a pin or a screw from the direction intersecting the axis of the shaft member. And workability is extremely poor.

  Furthermore, since a rod-like fixing member such as a pin or a screw prevents rotation between the cylindrical portion of the drive gear and the shaft member, the load is concentrated on this fixing member, and this load is repeated at the same position. Since it acts, a fixing member is easy to break.

  The present invention has been made based on such circumstances, and it is possible to easily attach the drive gear and the shaft member, to prevent stress concentration, and to obtain sufficient fixing strength at a low cost. An object of the present invention is to provide a fishing reel.
