2. Description of the Related Art FIG. 3 shows a conventional overall structure of an outboard motor, and FIGS. 4 and 5 show a conventional example of a handle mounting structure for the outboard motor. In these figures,
The outboard motor body 1 is an upper unit 2 that houses an engine and the like.
And a lower unit 4 accommodating a drive shaft (not shown) for transmitting the driving force of the engine to the lower screw 3 to rotationally drive the screw 3. The outboard motor body 1 is supported by a steering bracket 5, the steering bracket 5 is pivotally supported by a swivel bracket 6 via a pilot pin (not shown), and the swivel bracket 6 is supported by a clamp bracket 7. And is connected to the stern 8.

A handle 10 for adjusting the accelerator opening and for turning the outboard motor body 1 is fixed to one end of the steering bracket 5. The handle 10 is connected in such a manner that its base end 11 is sandwiched between one end surface of the steering bracket 5 and the end surface of the cover member 12.

That is, an end surface 5A formed in a substantially vertical direction is formed on one end surface of the steering bracket 5, and an end surface 12A that can contact the end surface 5A is formed on the cover member 12. The steering wheel 10 is connected to the steering bracket 5 via the bolt 13 and the nut 14 in a state where the both end surfaces 5A and 12A are in contact with each other. Further, the cover member 12 has a concave space 1 in which the base end 11 of the handle 10 can be accommodated.
2B is formed.

The connection by the bolt 13 and the nut 14 is performed by tightening the bolt 13 on the cover member 12 in advance and inserting the bolt 13 into the screw hole 5B formed in the end surface 5A, and then from the steering bracket 5 side. This is done by screwing 14 onto the bolt 13.

[0006]

However, in the above-mentioned conventional handle mounting structure, when the nut 14 is screwed, it is necessary to work in an extremely narrow space, and the connection of the handle 10 is relatively difficult. There was a problem that it was difficult.

Further, in the above-mentioned conventional structure, the structure of the casting mold for molding the steering bracket 5 is complicated, and a slide mold is required, which causes a problem of high manufacturing cost. However, there is a problem in that the boundary line that is a joint surface between the steering bracket 5 and the cover member 10 is exposed on the upper surface, and the appearance is deteriorated.

[0008]

SUMMARY OF THE INVENTION The present invention has been devised in view of the problems in the above-mentioned conventional example, and an object thereof is to facilitate the work of attaching the handle and to simplify the structure of each part of the connecting portion of the handle. It is an object of the present invention to provide a handle mounting structure for an outboard motor that reduces manufacturing costs and does not impair the appearance.

[0009]

In order to achieve the above object, the present invention provides a handle mounting structure for an outboard motor, wherein a handle is mounted between a steering bracket supporting a main body of the outboard motor and a cover member. The member is provided so as to be attachable to the lower surface side of the steering bracket, and a space capable of accommodating the base end of the handle is formed between the cover member and the steering bracket, and the base end of the handle is accommodated in this space. The steering bracket and the cover member are connected to each other via a fastener that extends in the vertical direction.

[0010]

The steering bracket is attached to the steering bracket by inserting the cover member after inserting the base end of the handle from the lower surface side of the steering bracket and inserting the fastening attachment from the lower surface side of the cover member to connect the cover member to the steering bracket. The handle is attached such that the base of the handle is housed in the space formed between the handle and the cover member.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described below with reference to the drawings. In the following description, the same reference numerals will be used for the same or equivalent components as in the conventional example, and the description will be omitted or simplified.

FIG. 1 is an external perspective view showing the present embodiment, and FIG. 2 is an exploded perspective view thereof. In these figures, a part of the steering bracket 5 is substantially U-shaped.
A notch 20 formed in a letter shape is formed, and a notch 21 corresponding to the notch 20 is formed in the cover member 12, and these notches 20, 21 cause
A space 22 that can accommodate the base 11 of the handle 10 is formed.

The facing surfaces of the steering bracket 5 and the cover member 12 excluding the notches 20 and 21 are formed flat so that they can come into contact with each other, and both members can be closely connected to each other. In addition, the cutouts 20 and 2
A passage 22 is formed at a relative position of the steering bracket 5 and the cover member 12 on one side of the steering wheel 5.
It is formed so that the flange portion 25 of the spacer 24 attached to the can be accommodated and the throttle wire 26 and the like held in the handle 10 can be guided.

A hole 28 is formed in the passage 22 of the cover member 12. A wing screw 30 inserted through a coil spring 29 can be screwed into the hole 28, and the tightening force of the wing screw 30 is applied to the flange portion 25 of the spacer 24, whereby the handle 10 Adjustments are made to absorb backlash.

Further, the cover member 12 has the cutout portion 21.
Holes 32 are formed in four places around the
Bolts 33 as tightening attachments that can be inserted from the lower surface side of the cover member 12 can be inserted into the inside of the cover member 2, and the tips of these bolts 33 reach screw holes (not shown) formed in the steering bracket 5. Is becoming Reference numeral 35 in the drawing is a spacer mounted between one side of the base end 11 of the handle 10 and a bearing portion 36 formed on the cover member 12.

In the above structure, when the handle 10 is attached, the spacer 2 is attached to the base 11 of the handle 10.
After setting 4 and 35 respectively, they may be integrally housed in the lower surface side position of the steering bracket 5, and then the cover member 12 may be further mounted from below and tightened via the bolt 33. At this time, the play of the handle 10 is absorbed by tightening the thumbscrew 30.

Therefore, according to such an embodiment, the mounting direction of the handle 10 is the vertical direction, that is, the direction from the lower surface side of the steering bracket 5 to the upper surface side, and the bolt 33 is also from the lower surface side of the cover member 12. Since the structure can be inserted, there is an effect that the nut tightening work in a narrow space as in the past can be wiped out, and the mounting work can be performed extremely easily and quickly.

Since the shape of the handle mounting portion is simpler than that of the conventional structure, the shape of the manufacturing die does not become complicated, and the manufacturing die itself can be manufactured at low cost. As a result, it is possible to greatly reduce the cost of the entire product.

Further, since the present embodiment is mounted in the vertical direction, the steering bracket 5 and the cover member 12 are
Since the boundary line between and appears on the side surface and does not appear on the upper surface, the appearance can be improved compared to the conventional example.

Further, when disassembling work, it is sufficient to loosen the bolts 33, and the reassembly is simple as described above. Therefore, maintenance work and inspection after the assembly such as the replacement work of the throttle wire 26 are easier and moreover, The effect is that it can be done quickly.

Although the four bolts 33 have been illustrated and described as the tightening tool, the number of the bolts used is not limited, and one end of the bolt is screwed into the steering bracket 5 using a stud bolt. Alternatively, the cover member 12 may be connected in such a manner that a nut is screwed onto the other end of the bolt. In this case, the steering bracket 5
When adjusting the positions of the cover member 12 and the cover member 12, there is an advantage that the workability can be further improved because the studs have a guide function.

[0022]

The present invention is constructed as described above, and
Since it works, according to this, when mounting the handle,
Since the space formed between the lower surface side of the steering bracket and the upper surface side of the cover member is used and the fasteners extending in the vertical direction are used, the handle mounting operation can be facilitated and There is an effect that the structure of each part of the handle connecting portion can be simplified to reduce the manufacturing cost, and a handle mounting structure for an outboard motor that does not impair the appearance can be provided.
