Description

[Detailed description of the invention] This invention enables the above-mentioned trip odometer to be operated by operating a reset knob protruding from the outside of the housing, which is housed inside the instrument housing of a motorcycle or other device that is exposed to the outside environment. The present invention relates to an operating device for returning to zero alignment, and particularly relates to the structure of a take-out portion when a reset knob is exposed on the outside of the front side of the instrument housing.

Generally, this type of trip totalizer is housed in an instrument housing, and the plurality of character wheels configured on the trip totalizer are operated by rotating or pressing a trip knob protruding from the outside of the instrument housing via a reset shaft. , is configured to reset.

By the way, the outlet of the trip knob configured in the above-mentioned trip totalizer is usually installed on the side of the instrument housing, and if it is installed on the side, even if rainwater, which is an external factor, falls on the instrument housing and the reset knob, water droplets will not be removed. Since water easily flows down and water can be discharged well, the airtight member interposed between the outlet of the housing and the reset knob can be achieved by relatively simple construction means.

However, due to operability issues, there are cases where it is necessary to install the trip knob outlet on the front side of the instrument housing. In this case, if rainwater falls on the front side of the instrument housing, water droplets tend to adhere to the housing, and as a result, rainwater seeps through the outlet of the reset knob formed in the housing and flows into the housing, damaging the instrument mechanism. As a countermeasure to this problem, the means for constructing the airtight member interposed between the outlet formed on the front side of the instrument housing and the trip knob has become complicated and expensive.

This idea focuses on the above problem, and
Preferred embodiments will be described in detail below with reference to the accompanying drawings.

1 and 2 show an embodiment of this invention. Reference numeral 1 denotes an instrument housing incorporating a trip totalizer mechanism (not shown). It is formed.

Also, on the front side of the front board 2 is the mounting hole 3.
An annular protrusion 4 is provided protrudingly along the entire circumference. A reset shaft 5 constitutes a part of the trip totalizer, one end of which is connected to the zero return mechanism in the instrument, and the other end connected to the mounting port 3 of the board 2.
A reset knob 6 is fixed to the other end.

Further, reference numeral 7 denotes a hollow airtight member made of an elastic material such as rubber, and the lower end of this airtight member 7 engages and is attached to the inner peripheral surface and back side peripheral edge of the mounting opening 3 of the board 2. Once the engaging portion 8 is formed,
A covering portion 9 is formed to cover the upper surface and outer circumferential surface of the annular protrusion 4 protruding from the substrate 2, and is further closely connected to the outer circumferential surface of the reset knob 6 by the inner circumferential surface of the hollow airtight member 7. A tightening portion 10 to be brought into contact is formed. In this case, an annular rib may be formed on the inner circumferential wall of the airtight member 7 to ensure effective close contact.

Also, a flange 11 is provided on the outer periphery of the lower end of the reset knob 6.
is formed inwardly of the flange 11 so as to cover the upper end of the hollow airtight member 7.

As in the above configuration, the mounting port 3 is formed on the front board 2 of the instrument housing 1, and the annular protrusion 4 is protruded from the entire periphery of the mounting port 3 on the front surface side of the front board 2.
An engaging portion 8 formed at the lower end of a hollow airtight member 7 made of an elastic material is engaged and fixed to the inner circumferential surface of the mounting opening 3 of the board 2 and the circumferential edge of the back side thereof, and
By covering the upper surface and outer peripheral surface of the annular protrusion 4 protruding from the board 2 with the covering part 9 formed on the airtight member 7, the airtight member 7 can be easily attached to the front board 2 of the instrument housing 1. Can be fixed.

Furthermore, by providing an annular protrusion 4 continuously above the mounting opening 3 opened on the front board 2 of the instrument housing 1, that is, on the surface side, rainwater can fall onto the front board 2 of the instrument housing 1. However, the rising portion of the annular protrusion 4 of the board 2 acts as a waterproof wall and can prevent water droplets from entering the inside of the instrument.
In order to do this more effectively, the covering part 9 of the airtight member 7 made of an elastic material is closely disposed on the upper surface of the annular protrusion 4 and its outer peripheral surface.
The waterproof effect can be improved more reliably.

Also, press the reset knob 6 at the upper end of the hollow airtight member 7.
By covering the reset knob 6 with a flange 11 protruding from the outer periphery of the lower end, rainwater can directly flow between the reset knob 6 and the airtight member 7.
Even if it rains heavily, water droplets adhering to the flange part 11 will flow down to the outside, and rainwater can be reliably prevented from entering from the joint between the airtight member 7 and the reset knob 6.
