ABSTRACT:
BACKGROUND OF THE INVENTION
The present invention relates to an operation cable mounting structure of an outboard motor.
Generally, in an outboard motor, a throttling operation or gear shifting operation is performed through a remote control manner, and cables or the like, such as throttle cable and shift cable extending from a remote control unit provided to an operation seat of a hull, for example, and other cables such as electrical equipment cable, are guided into the outboard motor through a port member or section having a cable insertion port or hole formed to a front portion of an engine cover covering an engine of the outboard motor.
The engine cover of the outboard motor is usually composed of a plurality of sections including an upper cover section and a lower cover section, the lower cover section being further composed of a bilateral pair of cover elements and a front cover element.
As mentioned above, since the engine cover is usually divided into a plurality of sections, in some arrangements, the port member is formed so as to straddle the plural cover sections such as one side cover element and the front cover element. In such arrangements, however, one port member half is provided with the cable insertion port, but the other one port member half is not provided with the cable insertion port, and accordingly, no cable is inserted through other one port section half. For this reason, in a conventional arrangement, the location of the cable insertion port is limited in its arranging position, and in a certain case, it is necessary to separately form insertion port for the electrical equipment cables.
SUMMARY OF THE INVENTION
The present invention has been conceived to consider such defects encountered in the prior art mentioned above and to provide an operation cable mounting structure of an outboard motor eliminating the limitation of the location or layout of the cable insertion port and capable of mounting a plurality of cables in an assembled state.
This and other objects of the present invention can be achieved by providing an operation cable mounting structure of an outboard motor in which an engine is covered by an engine cover composed of a plurality of cover elements and formed with a port member having an cable insertion port through which operation cables are guided inside an outboard motor, the operation cable mounting structure comprising:
a port member being arranged so as to straddle a plurality of the cover elements of the engine cover and composed of a first port member half provided to one of the cover elements and a second port member half provided to another one of the cover elements, the first and second port member halves having openings opposed to each other so that when the first and second port member halves are mated and joined together, the port member having a cable insertion port as a unit member having an opening;
a grommet closing the opening of the cable insertion port;
a partition wall section disposed in one of the first and second port member halves so as to divide the opening of the cable insertion port; and
a boss member provided for the partition wall section which is secured to the one of cover elements through a bracket.
In a preferred embodiment, there is further provided a cable holder secured to the bass member by means of fastener for holding the cables. The cables are separately arranged by means of the partition wall section.
The grommet is formed with a plurality of cable insertion holes through which the cables are separately inserted and also formed with a slit extending from one of the cable insertion holes towards an outer peripheral edge of the grommet.
According to the operation cable mounting structure of the present invention of the structure mentioned above, it becomes possible to eliminate the limitation of the location or layout of the cable insertion port and to mount a plurality of cables in properly shared state. Furthermore, many other advantageous functions and effects are obtainable such as disclosed in the last portion of the present specification.
The nature and further characteristic features of the present invention will be made more clear from the following descriptions with reference to the accompanying drawings.
