Abstract: PURPOSE: A bottom type governor for and oil hydraulic elevator is provided to easily inspect a governor by installing the governor at the bottom of a hoistway for safe work and to save cost. CONSTITUTION: As a governor rope(18) is connected with an elevator(110) and when the elevator descends, the governor rope moves downward to rotate a governor(10) and a tension pulley(20) respectively. When the governor reaches a predetermined speed, an electrical switch inside the governor is operated by centrifugal force and, by constricting the governor, an alarm stop device inside the elevator is operated to stop the elevator. A tension pulley rotates upwardly with the turning moment caused by weight while a tension pulley weight(22) tries to rotate downwardly. Correspondingly, the governor rope receives tensile force all the time. Likewise, the governor rotates according to the up and down motion of the elevator without sliding between the governor and the tension pulley installed at the bottom of a hoistway(100).
