A stop mechanism (23) of a helm device (16) includes a rotation member (80) which can be relatively rotated with respect to a steering shaft (22), rotatable disks (81), fixed disks (82) opposed to the rotatable disks (81), and an electromagnet (83) which presses these disks (81, 82) against one another. An inversion control pin (110) is provided in the steering shaft (22). Slits (120) are formed in a cylindrical portion (80a). Both ends of the inversion control pin (110) are inserted into the slits (120). The slits (120) are shaped to be elongated in a circumferential direction of the cylindrical portion (80a). A first pin receiving stopper wall (121) is formed on one end of the slits (120). A second pin receiving stopper wall (122) is formed on the other end of the slits (120). The inversion control pin (110) can move within the range of inversion allowance angle (¸) between the pin receiving stopper walls (121, 122). |
