PROBLEM TO BE SOLVED: To provide a compact governor capable of setting overspeed being an operation standard of the governor to a different value.SOLUTION: A sheave (101) of a governor (100) of the embodiment comprises a first sheave half body (101a) and a second sheave half body (101b) arranged in a rotation axial line direction of the sheave, and a drive mechanism moves the first and second sheave half bodies relatively in the rotation axial line direction, for changing a gap between the first and second sheave half bodies. By changing the size of the gap, winding radius (R) of a governor rope to the sheave, is changed, and thereby, a ratio of rotation speed of the sheave with respect to movement speed of the governor rope, can be changed.

    【課題】調速機動作基準となる過速度を異なる値に設定しうる調速機をコンパクトに形成する。【解決手段】本発明の実施形態の調速機(100)の綱車(101)は、綱車の回転軸線方向に並んだ第1の綱車半体(101a)及び第2の綱車半体(101b)を有しており、駆動機構により回転軸線方向に第1及び第2の綱車半体を相対移動させて、第1及び第2の綱車半体の間の隙間を変化させることができる。隙間の大きさを変化させることにより、綱車への調速ロープの巻き掛け半径(R)を変化させ、これにより、調速ロープの移動速度に対する綱車の回転速度の比率を変更可能とする。【選択図】図3
