It is a translucent colored cover. FIG. 5 is a view as viewed from B in FIG. In the figure, 14 is a set screw. FIG. 6 is a sectional view taken along the line CC of FIG.
It is the principal part sectional drawing seen from more.

Prior art swivel flasher devices 4L, 4R
As shown in FIG. 3, is mounted on, for example, the left and right rear end corners of the upper swing body 2 of the upper swing hydraulic excavator. When the upper swing body 2 turns, the flasher valves 6 and 7 (shown in FIG. 4) are provided. It flashes and emits a turn warning to surrounding workers.

[0004]

In the prior art swivel flasher device, a flasher valve is set up at the back of a bowl-shaped seat plate that is open obliquely rearward (specifically, at the back of the concave surface of the seat plate). It was mounted so that the direction center line was horizontal. Therefore, as shown in FIGS. 4 and 6, the protruding length t of the stem body of the flasher valve protruding toward the rear surface of the seat plate is considerably long. Therefore, since a depth dimension corresponding to the protruding length t is required, a considerably large-capacity mounting space S (shown in FIG. 4) is provided inside the conventional rotary flasher device. If the space S is large, not only the weight effect of the counterweight cannot be sufficiently exerted, but also the rear end turning radius R of the upper turning body (see FIG. 3).
This is inconvenient for a request to make the size as small as possible. An object of the present invention is to provide a mounting structure of a flasher valve that can solve the above problems.

[0005]

According to the present invention, a flasher valve is provided such that a vertical line of a vertical direction of the flasher valve is directed upward and downward with respect to a seat plate for supporting a flasher valve for flashing light emission for turning alarm. Was configured.

DESCRIPTION OF THE PREFERRED EMBODIMENTS Embodiments of the present invention will be described below in detail with reference to the drawings. FIG. 1 shows the turning flasher device 4 ′ of the present invention.
It is principal part sectional drawing of L. In the figure, 6 'and 7'
Is a flasher valve, 8 'is a stem body of each of the flasher valves 6' and 7 ', 15 is a bowl-shaped seat plate, 16 is a harness connected to the flasher valves 6' and 7 ', 17 is a counterweight, S 'Is sheet 1
5 is a space inside the revolving flasher device 4'L on the back surface side. FIG. 2 is a cross-sectional view of a main part taken along line DD in FIG. In the drawing, reference numeral 18 denotes a stem body of the flasher valve 6 '(the same applies to the flasher valve 7'), 19 denotes a grommet member, and 0-0 'denotes a vertical center line of the flasher valve 6'.

Next, the mounting structure of the flasher valve 6 'of the present invention will be described with reference to FIGS. The flasher valve 6 'is attached to the seat plate 15 for supporting the flasher valve 6' so that the vertical center line 0-0 'of the flasher valve 6' is directed in the vertical direction.

Next, the operation of the flasher valve 6 'of the present invention will be described. Since the vertical center line 0-0 'of the flasher valve 6' is attached to the seat plate 15 via the grommet member 19 so as to point in the vertical direction, the seat plate 1
Nothing protrudes on the back side of 5. Therefore, the space S ′ on the back surface side of the sheet plate 15 can be formed with a small capacity, and the counterweight 17 can be protruded left and right (the portion denoted by reference numeral a in FIG. 1 protrudes toward the space S ′). . Thereby, the weight effect of the counterweight 17 can be exhibited, and the counterweight 17 can be used.
The rear end turning radius can be slightly reduced.

[0009]

According to the prior art swivel flasher device, a flasher valve is attached to the back of a bowl-shaped sheet plate that is open obliquely rearward so that the center line in the vertical direction is horizontal. Therefore, the protruding length of the stem body of the flasher valve protruding toward the rear surface of the seat plate is considerably long. Therefore, the space on the back side of the sheet plate is large,
Not only can the weight effect of the counterweight not be sufficiently exerted, but also it is inconvenient for a request to reduce the turning radius of the rear end of the upper structure. However, in the present invention, the vertical line of the flasher valve is oriented in the vertical direction,
Since the flasher valve is mounted on the seat plate, there is no protrusion on the back side of the seat plate. Therefore, the space on the back surface side of the sheet plate can be made small, and the counterweight can be formed to protrude toward the space side.
As a result, the weight effect of the counterweight can be exhibited, and the turning radius of the rear end of the counterweight can be slightly reduced, so that the effect is large.
