A transom plate 3 is fixedly attached to the stern plate 2 by a pole 3A, and a swivel bracket 3B is supported on the transom plate 3 so as to be rotatable around a substantially horizontal axis. The swivel bracket 3BK supports the drive unit 4 so as to be rotatable around a substantially vertical axis. An intermediate clutch 6 is interposed between the drive unit 4 and the engine-side drive shaft 5.

している。That is, when propelling the hull 1, the intermediate clutch 6 connects the drive unit 4 and the drive shaft 5, so that rotational force can be transmitted to the propeller 14. On the other hand, hull 1
When operating the inboard auxiliary equipment with engine power while the engine is stationary, the intermediate clutch 6Vc releases the connection between the drive unit 4 and the drive shaft 5, thereby eliminating the need for the transmission shaft disposed inside the drive unit 4. This prevents the lubricating oil temperature within the drive unit 4 from rising abnormally.

Conventionally, it has been installed as shown in FIG. That is, a mounting opening 17 is provided in the stern plate 2, a mounting seat 18 formed on the transom grate 3 is disposed within this mounting opening 17, and a mounting portion 19 of the clutch housing 15 is mounted on this mounting seat 18. It is installed by 19A. If the transmission torque of the intermediate clutch 6 increases under the above mounting structure pressure, it becomes necessary to increase the size of the intermediate clutch 6 and the diameter of the mounting opening 17 provided in the stern plate 2. However, providing a large opening in the stern plate 2 as described above is not appropriate because the strength of the stern plate 2, which receives the propulsive reaction force generated by the propeller 14, is completely reduced.

In the above-mentioned installation condition, the tip tube part 24 which protrudes from the mounting 7 flange 22 of the clutch housing 21 and includes the bearing part of the output shaft 7 is inserted into the transom plate 3 within the opening 17A provided in the stern plate 2. It is installed in the insertion cylinder portion 25 formed on the side through a 26-karat gold O-ring. 'Furthermore, a reinforcing rib 27 is provided on the intermediate outer peripheral portion of the clutch housing 21 and is connected to the mounting flange 22VC.

Since the mounting portion of the clutch housing 21, that is, the mounting flange 22 is located outside the opening 17A of the stern plate 2, the strength of the stern plate 20 can be increased without increasing the diameter of the opening 17A. Under conditions to ensure
It becomes possible to increase the size of the clutch housing 21 and increase the transmission torque of the intermediate clutch 20.

Since it is arranged outside the opening 17A of the stern plate 2, it becomes possible to provide the entirety of the relatively large reinforcing lip 27 connected to the mounting 7 flange 22 on the outer surface of the clutch housing 21, thereby increasing the strength of the clutch housing 21 itself. It becomes possible to increase the Further, since the bolts 23 that attach the clutch housing 21 to the stern plate 2 are screwed to the transom grate 3, the transom grate 3 is fixed to the stern plate 2 by only the bolts 3A. The fixing strength to the plate 2 is increased.

This has the effect that a large-sized intermediate clutch can be installed without providing a large opening in the stern plate.
