PURPOSE:To tilt down a propulsive unit through only the operation of a tilt stop lever by interlocking a tilt lock mechanism with a tilt stop lever in an outer-ship machine. CONSTITUTION:A swivel bracket 14 where a propulsive unit is fixed is supported by a shaft 10 to a cramp bracket 4. A hydraulic operator 26 is fixed between the swivel bracket 14 and the cramp bracket 4 through the pins 30, 34. An unidirectional valve 44 for allowing the flow of the operating oil at the rising of the piston is provided on the piston 36 in the cylinder 28. A bypass 48 conducting between an upper oil chamber 38 and a lower oil chamber is formed in the cylinder 28 while a tilt lock valve or an unidirectional valve 52 is provided in said oil path. When positioning the tilt lever 74 at the locking position shown by the solid line, said valve 52 will function as an unidirectional valve. |
