A governor sheave in an elevator governor rotates in a first direction in association with the raising of a body being hoisted. A pawl holding mechanism maintains a state in which a pawl is engaged with a ratchet gear when the governor sheave rotates in the first direction from a stopped state due to a rope catch mechanism. The rope catch mechanism is coupled to the ratchet gear via a coupling pin. The ratchet gear is provided with a coupling pin hole. The coupling pin hole is an elongated arc-shaped hole. The pawl hold state due to the pawl holding mechanism is released by way of rotating thegovernor sheave in the first direction while the ratchet gear is stopped.
在电梯限速器中,限速器绳轮伴随着升降体的上升而向第1方向旋转。爪保持机构在限速器绳轮从通过绳索捕捉机构而停止的状态起向第1方向旋转时,保持爪咬入棘轮的状态。绳索捕捉机构借助连结销而与棘轮连结。在棘轮设置有连结销孔。连结销孔是圆弧状的长孔。爪保持机构对爪的保持状态是通过在棘轮停止的状态下使限速器绳轮向第1方向旋转而解除的。
