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. Accordingly, it is possible to compactly dispose the spool.對於紡車式捲線器的捲筒,可容易進行發聲機構的安裝,並且可以輕小地配置捲筒。安裝有發聲機構(90)的打擊構件(92)之環狀的安裝構件(20),是可裝卸地裝設固定在呈環狀凹陷形成於捲線胴部(4a)的內周部之安裝凹部(19)內。在此,環狀的安裝構件(20)因為是完全地裝設於呈環狀凹陷形成的安裝凹部(19)內,朝安裝構件(20)的安裝凹部(19)的組裝容易,並且捲筒(4)周方向的重量平衡可以均一地維持。且,在此,安裝構件(20)因為是裝設並安裝凹部(19)內,所以與習知的結構相比,因為安裝構件(20)不易從捲線胴部(4a)的後端部突出後方,所以捲筒(4)可以輕小地配置。4‧‧‧捲筒4a‧‧‧捲線胴部4b‧‧‧裙部4c‧‧‧前凸緣部4d‧‧‧內凸緣部4e‧‧‧外凸緣部4f‧‧‧後凸緣部4g‧‧‧筒狀部9‧‧‧凸緣固定構件9a‧‧‧公螺紋部15‧‧‧捲筒軸16‧‧‧筒狀部16a‧‧‧母螺紋部17‧‧‧圓板部18a‧‧‧支撐部18b‧‧‧支撐部19‧‧‧安裝凹部19a‧‧‧被卡止部20‧‧‧安裝構件20a‧‧‧卡止部45‧‧‧第1軸承46‧‧‧第2軸承60‧‧‧牽引機構61‧‧‧牽引調整旋鈕62‧‧‧制動部63‧‧‧旋鈕構件64‧‧‧按壓構件65‧‧‧旋鈕配件73‧‧‧密封構件75‧‧‧止拔彈簧90‧‧‧發聲機構91‧‧‧發聲構件91a‧‧‧凹凸部92‧‧‧打擊構件92a‧‧‧爪部93‧‧‧推迫構件94‧‧‧螺絲構件98‧‧‧環狀構件99‧‧‧板狀構件
