The present invention has a governor housing (98) connected to the outside of a motor partition wall (13) for sticking the motor axis (13-1) of a motor (M); comprises a brake pad (80) adhering to the motor axis (13-1) in the governor housing (98), and a shut-off valve brake pad (8) interlocking with a shut-off valve (9); and comprises a rotation detecting sensor (70) installed on the exterior side wall of the motor partition wall (13) to detect rotation via the existence of a magnetic force and conducting the function of encoding, and a governor device (90) including a magnet (83) installed radially on an axis joining protrusion (82) to recognize a rotational position and a rotating number via the rotation detecting sensor (70) and a governor lever (92) adhering to a governor axis (93). The brake pad (80) has, on a surface opposite a surface where the governor device (90) is installed, a pad panel (81) contacting with the shut-off valve brake pad (8) when a brake operates. |
