The rotating stay 17 is attached to the mounting stay 15 by being screwed into the mounting stay 15.

A screw hole 17c is formed in the rotation stay 17 in a direction perpendicular to the insertion hole 17b, and the bolt 20 inserted into the insertion hole 19b of the protrusion 19a protruding from the lower surface of the radar mounting plate 19 is inserted into the screw hole 17c.
The radar mounting plate 19 is attached to the rotary stay 17 by being screwed into the rotary stay 17.

Therefore, if the bolt 16 is loosened, the mounting stay 15
can be rotated in the horizontal direction around the insertion hole 15a, and by loosening the bolt 18, the rotation stay 17 can be rotated in the vertical direction, and by further loosening the bolt 20, the radar mounting plate 19 can be rotated in the left-right direction. It is possible.

That is, the radar mounting plate 19 can freely rotate in three directions of X-Y-Z, and the bolts 16, 18, 20
It is fixed at that angle by tightening.

On the upper surface of the radar mounting plate 19, the intervals widen in a tapered manner as they reach the sides in a symmetrical manner.
In addition, a pair of guide tapered pieces 19 project outward in a tapered shape as the outer side reaches the upper end.
c is provided in a protruding manner, and the subframe 21 is attached to the side of the radar mounting plate 19 opposite to the guide tapered piece 19c.

A slide groove 21a is formed between the sub-frame 21 and the radar mounting plate 19, and side end portions 22a hanging down on the left and right sides of the terminal cover 22 are slidably inserted into the slide groove 21a. There is.

Further, two terminal plates 24 which are urged upward by springs 23 are housed in the sub-frame 21 so as to be slidable up and down, and normally the upper surface of the terminal plates 24 is covered with a terminal cover 22.

Further, this sub-frame 21 accommodates a cover stopper 26 adjacent to the housing portion of the terminal plate 24, which is biased upward by a spring 25 and has tapered surfaces on both front and rear surfaces.

This cover stopper 26 is pressed against the terminal cover 22 by the bias of the spring 25 when the terminal cover 22 is slid from above the terminal board 24 and is moved onto this, and keeps the terminal cover 22 in that position. It is something.

A stopper 27, which is biased upwardly by a spring 27c, is pivotally attached to the subframe 21 at a shaft 27d, and the stopper portion 27a projects upwardly from the upper surface of the subframe 21.
The operating piece 27b is exposed on the front surface of the subframe 21, and when the operating piece 27b is pushed down against the spring 27c, the stopper portion 27a is retracted from the upper surface of the subframe 21.

FIG. 8 shows a rear perspective view of a storage box 28 for a radar detector to be attached to the radar mounting plate 19, and inside it is a board 2 with circuit components attached.
9 is accommodated, and a diamond-cut luminous plate 30 is attached so that it shines with a flashing lamp when radar is detected.

In the bottom plate 31 of the storage box 28, a terminal 32 that contacts the terminal plate 24 is inserted into the downwardly protruding portion 31a, and the board 29 is attached to the terminal 32 with screws 33. , the power supply line and ground line of the circuit are connected to the terminal 32.

The terminal 32 is attached to the terminal plate 24 on the bottom plate 31.

Push the terminal cover on and slide it into the guide groove to remove it from above the terminal board.

At the same time, the terminal on the bottom of the storage box contacts the terminal board, and the radar detector circuit is automatically connected to the power source such as the motorcycle's generator or battery, so the radar detector is connected to the power source using the connector. Eliminates the hassle of connecting.

When the storage box is slid in the opposite direction to remove it from the radar mounting plate, the terminal cover is pushed by the other protrusion and slides onto the terminal board to cover it.

Therefore, poor contact due to dust adhering to the terminal board and shorts due to raindrops adhering to the terminal board can be prevented without requiring the trouble of attaching another cover over the terminal board.

Therefore, the radar detector's circuitry must always be reliably connected to a power source to operate properly.
