The invention provides a double bearing fishing reel having a depth water display portion and an actuating mechanism prone to process switch operation of the actuating mechanism. The double bearing fishing reel includes a handle, a fishing reel main body, a winding reel for winding, a depth water display portion, a winding reel sound mechanism and a sound operation button. The fishing reel main body includes a first side cover having a projection portion projecting toward side part and covering outside of the first side broad. The depth water display portion is accommodated in the projection and linked to rotation of the winding reel to display depth water where a fishhook assembly in electronic way. The winding reel sound mechanism, which is linked to the rotation of the winding reel to sound, is a mechanism switching between a sounding state and a non-sounding state. The sound operating button is configured at position nearing a fishing rod mounting base with respect to the projection portion and is mounted on the first side cover in a way of moving along direction departed or adjacent to the projection portion to switch the winding reel sound mechanism between the sounding state and the non-sounding state.本發明之課題在於，針對具有具有水深顯示部與動作機構之雙軸承捲線器，容易進行動作機構的切換操作。用以解決課題之手段為，雙軸承捲線器是具備有：手把；捲線器本體1；捲筒12；水深顯示部13；捲筒發聲機構14；及發聲旋鈕16。捲線器本體具有第1側蓋6，該第1側蓋，於側方具有部分突出之鼓起部6a、用以覆蓋第1側板的外側。水深顯示部是被收納於鼓起部的內部，連動於捲筒的旋轉，可電性顯示釣組的水深。捲筒發聲機構可連動於捲筒的旋轉而發聲，可切換成可發聲狀態與不能發聲狀態之機構。發聲旋鈕是比起鼓起部，更配置於接近釣竿安裝部4，可朝與鼓起部接觸分離之方向自由移動地裝設於第1側蓋，將捲筒發聲機構切換成可發聲狀態與不能發聲狀態。
