Description

  The present invention relates to an operating device for a marine propulsion device having a rotary operating lever.

  Conventionally, as an operation device for remotely operating a throttle device or a shift device of a propulsion device in a small boat, there is one disclosed in Patent Document 1, for example. The operation device shown in Patent Document 1 is composed of two rotary operation levers and an operation device main body that rotatably supports these operation levers. Installed on. The operating lever is provided on both sides in the left-right direction of the operating device main body so as to be positioned on the same axis.

The operating device main body includes a driven member interlocked with the operating lever and a housing that accommodates the driven member. The rotating shaft of the operating lever is positioned at a position higher than the outer surface of the operating panel. A part of the member is attached to the operation panel in a state of being positioned below the operation panel.
In the conventional operation device configured as described above, the rotation shaft of the operation lever is positioned at a position spaced apart from the outer surface of the operation panel. Therefore, when the driver operates the operation lever. I need to raise my arms high.

  In order to solve such a problem, it is conceivable to adopt a configuration in which the operating device main body is disposed at a deeper position below the operating panel, and only the operating lever protrudes from the operating panel. In order to adopt this configuration, a hole for passing the operation lever through the operation panel is formed so that the operation lever can be rotated.

  An operation panel for a propulsion device in a general type ship is often installed in a place where splashes from rainwater and waves hit, and water such as splashes from rainwater and waves may be applied. In such a case, water permeates into the lower part of the operation panel from the lever insertion hole, and wets the lower part of the operation device main body and other parts provided in the operation panel. In order to prevent this water from entering, for example, a waterproof structure shown in FIG. 9 may be adopted.

  FIG. 9 is a perspective view showing an operating device of a conventional small marine vessel propulsion device. In FIG. 9, reference numeral 1 denotes a rotary operating lever, and 2 denotes an upper plate of the operating device main body 3. FIG. 9 is drawn with the lower part of the operating device main body omitted. Four operating levers 1 are provided, and each of the operating levers 1 is rotatably provided on the operating device main body 3. The upper plate 2 is attached to be overlapped on an operation panel (not shown), and has a slit (not shown) through which the operation lever 1 is passed.

In the opening portion of the slit, a long and narrow rubber plate 4 for sealing is provided to cover the slit from above. The central portion of the sealing rubber plate 4 in the width direction of the slit is cut in a stripe shape in the longitudinal direction of the slit. In other words, the sealing rubber plate 4 is provided with two lips 4a and 4a that are formed in an elongated shape and come into contact with each other. The operating lever 1 passes through the sealing rubber plate 4 in a state where the cut portion (the lip 4a) of the sealing rubber plate 4 is pushed and spread in the lateral direction. That is, the sealing rubber plate 4 prevents water from entering by the lip 4a coming into contact with the operating lever 1 by its own elasticity in the portion where the operating lever 1 is inserted, and in the other portion the lip The front end portions of 4a and 4a are in contact with each other to prevent water from entering.
JP-A-10-198451 (page 3-5, FIG. 11)

  However, the rubber plate 4 for sealing shown in FIG. 9 cannot bring the lips 4a into contact with each other at the front portion and the rear portion in the direction in which the operation lever 1 rotates. There was a problem of intrusion. In addition, the sealing rubber plate 4 may be deteriorated or worn when used for a long period of time. In such a case, a gap is formed between the lips 4a so that water can enter from there. Become. In order to prevent the ingress of water in this type of operating device, it must be avoided that the manufacturing cost increases due to a highly accurate waterproof structure.
