Patent number: 7401748Abstract: An object of the present invention is to make it possible to easily attach a sound producing mechanism to a spool of a spinning reel and to compactly dispose the spool. An annular attachment member to which a hitting member of a sound producing mechanism is attached is detachably/reattachably mounted and fixed in an attachment recess that is formed to be annularly concaved in an inner peripheral portion of a bobbin trunk. Here, the annular attachment member is completely mounted in the attachment recess that is formed to be annularly concaved. Accordingly, it is possible to easily attach the attachment member to the attachment recess, and it is also possible to uniformly maintain the weight balance of a spool in the peripheral direction. In addition, here, the attachment member is mounted in the attachment recess. Thus, the attachment member is not likely to protrude backward from a rear end portion of the bobbin trunk, compared to the conventional configuration.Type: GrantFiled: November 16, 2007Date of Patent: July 22, 2008Assignee: Shimano Inc.Inventors: Keigo Kitajima, Hirokazu Hiraoka, Shingo Matsuo

The tip of the pawl member is arranged to be contactable with the concave/convex portions, and the concave/convex portions repeatedly contact with the pawl member to produce sounds when the spool is rotated. In a sounding mechanism of a spinning reel, the spool can rotate smoothly, while clear, crisp sounds can be obtained.Type: GrantFiled: September 30, 2004Date of Patent: February 13, 2007Assignee: Shimano Inc.Inventor: Takeshi Ikuta
