PROBLEM TO BE SOLVED: To prevent the damage of an engine by providing a connecting part whose longitudinal length is changeable according to the force added to a bracket when the engine is collided with an object. SOLUTION: A clutch assembly is formed of an upper channel as first link, a clutch channel as second link, a clutch shim as barrier means, and a mechanical fastener as connecting means. The clutch channel is connected to a mount bracket 70 by a pivot, and connected to the upper channel through the clutch shim in such a manner as to be slidable. When an engine is collided with an obstruction, the clutch friction between the upper channel and the clutch shim is overcome with it. Then, the clutch channel extends the upper member of a mounting part 13 forward through a linear slot, so that the bracket 70 is rotatable on a bow arm 9 mounted on the deck channel 5 to absorb most of the impact. |
