PROBLEM TO BE SOLVED: To provide a gear with a magnet having a structure capable of preventing falling of a sensor magnet from the gear, preventing the sensor magnet from being brought into contact with a magnetic sensor by vibration, preventing a manufacturing device such as a heating head from being brought into contact with the sensor magnet in fixing the sensor magnet, and easily fastening the sensor magnet to the gear.SOLUTION: A gear with a magnet is the gear having the circular shape when observed from an axial direction and having external teeth on an outer periphery, and includes a magnet inserting portion, a plate for closing at least a part of the magnet inserting portion, fixing means for fixing the plate disposed on the gear, and fixed means disposed on the plate and engaged with the fixing means. The magnet is supported between the magnet inserting portion and the plate.SELECTED DRAWING: Figure 4

    【課題】センサ磁石が歯車から脱落することを防ぐことができ、振動によりセンサ磁石が磁気センサに接触することを防ぐと共に、センサ磁石の固定時に加熱ヘッド等の製造装置がセンサ磁石に接触することを防ぎ、かつ、センサ磁石を歯車に固着することが容易な構造の磁石付き歯車を提供すること。【解決手段】本発明の磁石付き歯車は、軸方向から見て円形であり、外周に外歯が形成された歯車であって、磁石挿入部と、磁石と、前記磁石挿入部の少なくとも一部を閉塞するプレートと、前記歯車に設けられた前記プレートを固定するための固定手段と、前記プレートに設けられ、前記固定手段と係合する被固定手段とを備え、前記磁石は前記磁石挿入部と前記プレートとの間に支持されていることを特徴とする。【選択図】図4
