The first cable outer 13 and the inner 14 of FIG. 1 constitute a control cable device 17 of the present invention, which is linearly pulled by an operator (not shown) at the time of operation, but is not operated. Sometimes it is stored in a bent state.

In FIG. 5, the end portion 13 of the first cable outer 13
The transmission mechanism 20 is connected to b. The transmission mechanism 20 includes a connecting fitting 21 fixed to the end portion 13b,
The second cable inner 22 and the second cable outer 23
Consists of. The second cable inner 22 is connected to the connecting fitting 21 and is guided by the second cable outer 23. The second cable inner 22 is connected to the throttle valve (not shown) of the carburetor in the engine 3 of FIG. The opening is adjusted.

Next, the starting device which is the main part of this invention will be described.

In FIG. 1, the small engine 3 has a recoil starter 3a shown by a broken line, and is started by a manual pulling operation of the recoil rope 30, as is well known. The recoil rope 30 is linearly arranged in the surfboard body 6 from the small engine 3 to the front end portion 6b of the surfboard body 6, and via a rotatable pulley 31 provided in the front end portion 6b. It is led out to the rear B outside the surfboard body 6. Further, the recoil rope 30 is arranged along the control cable device 17,
The control grip 5 side (front side C) is extended almost in parallel.

In FIG. 4, the extension end 3 of the recoil rope 30 is shown.
The bracket portion 32a of the recoil knob 32 is tied and attached to 0a. The recoil knob 32 is
It is slidably mounted on the first cable outer 13 of the control cable device 17. In this embodiment, the first cable outer 13 is inserted through the recoil knob 32.

A stopper 33 is provided slightly F in front of the recoil knob 32.
Are fastened and fixed to the first cable outer 13 by screws 33a. This stopper 33 is the first
This prevents the recoil knob 32 shown in the figure from sliding down to the front F.

Next, the operation of the above configuration will be described.

First, at the time of starting, the operator riding around the center of the surfboard body 6 leans forward while looking at the front F, and grasps the control grip 5 with one hand h as shown in FIG. The other hand (not shown) grasps the recoil knob 32 of FIG. 1, and the recoil knob 32 is pulled along the control cable device 17 toward the front side C. Thereby, the recoil rope 30 is led out from the recoil starter 3a, and as is well known, the small engine 3 is started and the surfboard 1 is started via the recoil starter 3a.

Simultaneously with the start of the operation, the operator operates the one hand h (second
(Fig.) With the palm of your hand, move the grip body 8b in Fig. 3 forward F
Press to. With this pressing operation, the accelerator grip 8,
The first cable outer 13 and the connecting fitting 21 of FIG.
Moves forward F. By this movement, the second cable inner 22 is pulled forward F, the opening degree of the throttle valve (not shown) is increased, and the rotational speeds of the engine 3 and the water jet propulsion device 2 shown in FIG. 1 are increased to increase the surfboard 1.
Is accelerated. When shifting from the starting operation to the accelerating operation, the operator glides while keeping the first cable inner 14 in a stretched state as shown in the drawing while keeping a slightly tilted posture (see FIG. 7).

On the other hand, at the time of starting after the engine stall, the operator grips the control grip 5 shown in FIG. 3 firmly, moves the inner surface 8e of the grip body 8b to the position indicated by the alternate long and short dash line, and with the throttle valve fully opened, the recoil knob is opened. 32 pulling operation. The subsequent operation is the same as the normal starting and accelerating operations, and detailed description thereof will be omitted.

In the above structure, in the present invention, the recoil rope 30 of FIG. 1 is led out to the rear B from the pulley 31 of the front end portion 6b of the surfboard body 6. For this reason, the operator pulls the recoil knob 32 toward the front F, so that the operator can move from the forward leaning posture at the time of starting to the posture (see FIG. 7) at the time of gliding.

Further, the recoil rope 30 is extended to the control grip 5 side. For this reason, the operator must use one hand h
(Fig. 2) Grasp the control grip 5 firmly to fully open the throttle valve, pull the coil knob 32 to the front C with the other hand, and then loosen the grip of the accelerator grip 8 in Fig. 2 to open the throttle. The degree can be adjusted immediately. Therefore, the operation at the time of starting after the engine stall is also possible.

Further, in this invention, the recoil rope 30 of FIG. 1 is extended to the front C along the control cable device 17, and the recoil knob 32 is slidably attached to the control cable device 17. Therefore, the pulling direction of the recoil knob 32 is regulated in the front C direction, and thus is regulated in the longitudinal direction of the surfboard 1 which is long. Therefore, the pulling operation of the recoil knob 32 in which the reaction force fluctuates can be performed even on the floating surfboard 1.

By the way, in the above embodiment, the control cable device 17 is composed of the first cable inner 14 and the outer 13. However, in this invention, the control cable device 17 may be of a hydraulic type as shown in FIG. 7, for example.

[Effect of device]

As described above, according to this invention, the operator can move from the starting posture to the sliding posture, and the pulling direction of the recoil knob is restricted to the front-back direction of the surfboard. Therefore, starting becomes easier. Moreover, since the control grip and the recoil knob can be operated simultaneously, the operation at the time of starting after the engine stall is also possible.
