## Abstract

A steering handle device includes a housing to be mounted on a hull, a tube member and a steering shaft. The tube member is rotatable in a forward/backward direction around the tilt shaft relative to the housing. The steering shaft is inserted to the tube member. A steering arm is attached to the steering shaft. The steering arm includes an extending portion extending to an outer side of the housing. A joint member is provided on the extending portion. The joint member includes a connection portion to connect to the steering cable and a support portion to support the connection portion. When the steering shaft is in the neutral position in the rotation direction, the connection portion is located in a position corresponding to the tilt shaft as viewing the housing from the lateral direction.

## Claims

### Claim 1

A steering handle device for a vessel, comprising:
a housing including a space therein;
a tube member inserted to the space of the housing and supported by a tilt shaft having a first axis rotatably back and forth with respect to the housing;
a steering shaft including a handlebar in an upper portion, having a second axis extending in a length direction, inserted into the tube member, and being rotatable about the second axis with respect to the tube member;
a steering arm provided on the steering shaft and including an extending portion extending toward an outer side of the housing; and
a joint member provided on the steering arm, including a connection portion to which a joint mechanism of a steering cable is connected, and including a support portion which support, when the steering shaft is in a neutral position in a direction rotation, the connection portion in a position corresponding to the tilt shaft as viewed from a lateral direction of the housing.

### Claim 2 (depends on 1)

The steering handle device according to claim 1, wherein
a part of the connection portion is a rotationally symmetric shape of a spherical surface, and
the connection portion is placed in a range in which the tilt shaft is extended in a direction along the first axis in a state where the steering shaft is in a neutral position in the rotation direction.

### Claim 3 (depends on 2)

The steering handle device according to claim 2, further comprising:
an offset wall formed of a side wall of the housing between the second axis and the tilt shaft as viewed from a lateral direction of the housing, which shifts a position of the tilt shaft in a forward/backward direction with respect to the second axis.

### Claim 4 (depends on 1)

The steering handle device according to claim 1, wherein
the housing includes a flange portion on a lower portion thereof, which is fixed to a mount surface on an outer side of a hull in a state where the housing, the tube member, the steering shaft, the steering arm, and the joint member are each positioned on an outer side of the hull.
