On the upper surface of the central part of the bearing holder 5,
The lead wire cover described later is attached to the guide plate 3.
A recess 5a is provided along the inner surface of the top wall 3a of the bearing holder 5, and a frame 8 is rotatable at the bottom of the bearing holder 5 by a vertical shaft 7 and fixed by tightening a tightening lever 9. A motor case 12 of a cutter part 11 is rotatably supported on the frame 8 by a horizontal shaft 10, and fixedly supported by tightening the horizontal shaft 10.

Further, the frame 8 with respect to the bearing holder 5 and the motor case 12 with respect to the frame 8 are provided so as to be fixed at angles adjusted by stopper pins 13 and 14, respectively.

A switch case 15 is fitted and fixed to the front end of the guide plate 3 by screws 16, and a switch 17 built into the switch case 15 has an ON switch button 18 and an OFF switch button 19. In addition, the switch has a plug (not shown) attached to one end, the other end of the cord 20 is connected to a power socket, and one end is connected to a motor (not shown) housed in the motor case 12. The other ends of the cords 21 are connected to each other.

The lead wire cover 22 for storing and holding each of the cords 20, 20 is formed into a long length with a substantially upwardly U-shaped cross section using a U-shaped channel member or the like.

On the other hand, on the back of the switch case 15 and the opposing part of the guide holder 23 of the elevating means 4, grooves 24 and 25 having a substantially square shape from the front are provided so as to be able to fit into the end of the lead wire cover 22. The lead wire cover 22 is installed inside the guide plate 3 by fitting each end into the respective grooves 24 and 25, and the lead wire cover 22
The upper opening of is the top wall 3a of the guide plate 3.
Cord storage section 2 with a rectangular cross section
6 is arranged between the switch case 15 and the elevating means 4.

Further, one end of the guide plate 3 is fixed to the upper end surface of the guide holder 23 in a stacked state with bolts 41, etc.
The lead wire cover 2 is assembled by fitting the lead wire cover 5 into the guide plate 3 as described above and then fixing it with the screws 16.
For example, when fixing the guide plate 3 to the guide holder 23, one end of 2 is fitted into the groove 25 of the guide holder 23, and then, when the switch case 15 is fitted to the guide plate 3, the other end is fitted into the groove part 25 of the guide plate 3. Fits into the groove 24 of the case 15,
Next, the switch case 15 is attached to the guide plate 3.
It is constructed so that it can be assembled simultaneously with other members by fixing it with screws 16 . . . .

Also, when assembling the lead wire cover 22 as described above, both the cords 2 are placed in the storage portion 26 formed between the cover 22 and the guide plate 3.
0 and 21, one of the cords 20 is placed near the guide holder 23 of the lead wire cover 22,
Or a notch 27 in an appropriate place of the guide holder 23.
etc. and extend outward. Also, the other code 2
1, an opening 28 may be provided at a suitable location on the top wall 3a or the like of the guide plate 3 to extend outward and connect to the motor.

Further, the lifting means 4 in the illustrated example attaches the guide holder 23 to the column 2 with a key 29 and key grooves 30, 30.
The guide holder 23 is set against the column 2 by making it non-rotatable and slidably mounted by a, and by loosening and tightening the slit 31 vertically provided at the lower part of the peripheral wall of the guide holder 23 with the lever handle 32. A feed screw rod 36 is screwed into a screw hole 35 of a screw holder 34 which is slidably and fixedly fixed to the upper end of the column 2 using a spring pin 33 or the like, and the feed screw rod 36 is attached to the guide plate 3. The guide holder 23 and the guide plate 3 are formed such that the guide holder 23 and the guide plate 3 can be moved up and down by the handle 37 being fixed to the extending end of the handle 37. There is.

Further, the cutter section 11 has a motor case 12.
, a motor (not shown), a circular saw 38 rotated by the motor, a safety cover 39, an operating handle 40, and the like.

In addition, in FIG. 4, 42 indicates a table.

[Effect of idea]

As explained above, the lead wire cover attachment device for a radial arm saw according to the present invention is constructed so that the guide plate 3 supports the blade part 11 so as to be movable back and forth and adjustable in rotation in two axial directions. Between the guide holder 23 of the elevating means 4, which is located inside and has its base end fixed, and the switch case 15 attached to its distal end, a The lead wire cover 22 can be attached at the same time as other components by simply fitting each end into the grooves 24 and 25, and structurally, the lead wire cover 22 has a substantially upward U-shaped cross section. The switch case 15 and the guide holder 23 are simply formed with grooves 24 and 25 that fit the respective ends of the grooves 24 and 25, and the assembly is also extremely easy compared to conventional products. You can drastically reduce costs by
Further, since the upper opening of the lead wire cover 22 is closed by the top wall 3a of the guide plate 3, and the storage section 26 is configured in a closed type, the cords 20 and 21 can be stored and held securely. There is an effect.
