    &Lt; Driven driven body 353 &gt;

5 (a) to 5 (c) are explanatory diagrams of the driven member 353. More specifically, Fig. 5 (a) is a perspective view of the driven member 353, Fig. 5 (b) is a view of the driven member 353 from below, Sectional view along the up-and-down direction.

More specifically, the pitch of the interdental spaces in the trapezoidal serrations 357 is smaller (narrower) on the upper side than on the lower side.

5 (c), the inclination angle? In the trapezoidal serration 357 is, for example, 5 to 30 degrees, preferably 10 to 25 degrees, more preferably 15 degrees To 20 degrees.

    &Lt; Moving body 37 &gt;

Fig. 6 is an explanatory view of the moving body 37. Fig.

Next, the moving body 37 will be described with reference to Fig.

As described above, the moving body 37 is provided with the slide block 371, the slide gauge 373, and the connecting member 375.

The slide block 371 is a substantially rectangular parallelepiped member and has a through hole 372 through which the rotation shaft 352 passes. A thread groove (male thread) (not shown) engaging with a thread groove (male thread) 351 of the rotating shaft 352 is formed on the inner peripheral surface of the through hole 372.

The slide gauge 373 is an elongated member. The slide gauge 373 is disposed along the vertical direction.

Next, the operation of the rotating body 35 and the moving body 37 will be described with reference to Fig.

First, when the rotating shaft 352 of the rotating body 35 rotates, the slide block 371 provided on the rotating shaft 352 tries to rotate together with the rotating shaft 352. [ On the other hand, the slide block 371 is supported by the moving body support portion 317 of the main body 31 via the slide gauge 373. Therefore, the rotation of the slide block 371 together with the rotation axis 352 is suppressed.

In this state, when the rotary shaft 352 rotates, the slide block 371 moves in the vertical direction. As the slide block 371 moves, the connecting member 375 rotates the rotary arm 730 (see Fig. 1). As a result, the beam tilt angle is changed.

As the slide block 371 moves in the vertical direction, the slide gauge 373 moves in the vertical direction. By this movement in the up and down direction, the amount by which the slide gauge 373 protrudes from the through hole 3171 (see distance P1 in the figure) changes. The rotation angle (beam tilt angle) of the rotation shaft 352 can be detected from the outside by grasping the amount of the projection by the scale (not shown) formed on the surface of the slide gauge 373 .

[ More specifically, before the outer member 324 and the inner member 326 constituting the main body 31 of the main body 31 are fitted to each other, the substrate main body 391 is moved from the inner peripheral surface side of the outer member 324 And inserted into the terminal supporting portion 319.

The side of the board main body 391 inserted into the terminal supporting portion 319 is positioned inside the main body 31 where the curved notch 393 is formed and the side to which the cable 395 is connected is protruded outside the main body 31 . 7 (c), the curved notch 393 is disposed along the inner circumferential surface of the rotation support portion 315 of the main body 31.

Further, the transmission unit 50 receives a control signal via the casing terminal 39. The transmission unit 50 that receives the control signal drives the motor 52 and rotates the driven member 353 through the driving unit 56. As the driven member 353 rotates, the connecting member 375 (see FIG. 1) moves, and as a result, the beam tilt angle of the antenna 1 (see FIG. 1) is changed.

In other words, the cross-sectional area of the unit body 51 is suppressed by arranging the motor 52 and the pot 53 in the vertical direction, and consequently, the area occupied by the electric unit 50 in the lower lid 115 is suppressed do.

    &Lt; Upper end of electric transmission unit 50 &gt;

Figs. 9 (a) to 9 (d) are explanatory diagrams of the upper end of the electric unit 50. Fig. 9 (b) is a side view of the drive unit 56, and Fig. 9 (c) is a plan view of the drive unit 56 viewed from above. Fig. 9 (d) is a perspective view of the vicinity of the unit terminal 55 of the electric power unit 50. Fig.

Next, the upper end of the electric unit 50 will be described with reference to Figs. 9 (a) to 9 (d). The upper end portion of the transmission unit 50 is a front end portion in the insertion direction of the transmission unit 50 from the lower side to the upper side.

First, as shown in Fig. 9 (a), a drive unit 56 is provided at the upper end of the electric unit 50. Fig. As shown in Fig. 9 (b), the driving portion 56 is substantially cylindrical and has an outer periphery on the outer periphery thereof, which is engaged with the inner teeth 355 (see Fig. 5 (a)) of the driven body 353, ) 561 are formed. As shown in Fig. 9 (c), a chamfer 563 is formed on the upper side (tip side) of the external tooth 561. [

The driving portion 56 enters the opening 354 (see Fig. 5 (a)) of the driven member 353 and meshes with the driven member 353 to transmit the driving force of the motor 52. In other words, the driving portion 56 and the driven member 353 function as a transmitting portion for transmitting the output of the motor 52. [

More specifically, in the operation in which the drive unit 56 enters the opening 354 even when the rotation angle of the internal teeth 355 and the external teeth 561 is out of alignment when the transmission unit 50 is inserted, The external teeth 561 of the internal teeth 56 push the serration serrations 357 (see Fig. 5 (a)) of the internal teeth 355. The driven member 353 is manually rotated and the angles of the internal teeth 355 and the external teeth 561 match each other. As a result, the inner teeth 355 and the outer teeth 561 are in mesh with each other. In other words, the trapezoidal serrations 357 adjust the rotation angle of the internal teeth 355 and the external teeth 561. 5A) of the driven member 353 more smoothly by setting the inclination angle? In the trapezoidal serration 357 to an appropriate value as described above, You can.

Incidentally, as shown in Fig. 9 (d), a unit terminal 55 is provided at the upper end of the electric unit 50. [ This unit terminal 55 is constituted by a resiliently deformable contact (so-called spring contact).

The unit terminal 55 contacts the substrate main body 391 (see Fig. 7 (a)) of the casing 30 to transmit the control signal of the electric motor unit 50 with the substrate main body 391.

The unit terminal 55 is elastically deformed to maintain electrical connection with the substrate main body 391 even when the position of the electric unit 50 in the up and down direction varies.

3) of the casing 30 (refer to Fig. 3), the drive unit 56 is connected to the driven member 353 with each other The unit terminal 55 is electrically connected to the casing terminal 39 in addition to the engagement (engagement). That is, the transmission unit 50 is mechanically and electrically connected to the casing 30 by being inserted into the casing 30. [

In the present embodiment, the position of the unit terminal 55 is the upper end of the electric unit 50. However, this position is not limited to the upper end, but may be the middle of the upper side portion or the upper portion of the electric unit 50 It is also good.

According to the present embodiment, even if the motor 52 provided in the electric power unit 50 fails after the antenna 1 (see Fig. 1) is installed, for example, the antenna 1 is stopped It is possible to cope with the failure. More specifically, the failed electric transmission unit 50 can be pulled out and replaced with a new electric transmission unit 50 while the antenna 1 is being operated, without removing the entire antenna 1. Further, the motor 52 can be exchanged without disassembling the antenna 1.

    &Lt; Fixed Mode of Electric Transmission Unit 50 &gt;

10 is an explanatory view of the fixing of the electric unit 50. Fig.

Next, a description will be given of a mode of fixing the electric unit 50 to the casing 30 with reference to Fig.

10, the transmission unit 50 is fixed to the casing 30 via the tread portion 323 of the casing 30 and the bolt 61. As shown in Fig. More specifically, the flange 58 of the electric unit 50 is pressed by the tread 323 and the bolt 61. Thereby, the electric unit 50 is fixed (the movement in the vertical direction is restricted).

Next, the operation from when the electric unit 50 is inserted into the casing 30 to when it is fixed will be described.

First, when the electric unit 50 is inserted, the tubular portion 323 is elastically deformed and is retracted from the passage of the electric unit 50. When the electromotive unit 50 is moved in the inserting direction and the flange 58 passes, the tubular portion 323 is caught by the flange 58. Thus, even when the operator erroneously releases his / her hand, for example, the electric unit 50 is prevented from falling out (falling) out of the casing 30. In other words, the tread portion 323 can be grasped as a fall preventing mechanism that suppresses the electric power unit 50 from dropping.

In this state, the bolt 61 is fixed to the through hole 59 formed in the flange 58. In other words, the fixing is carried out in two steps of fixing the electric unit 50 by the tread part 323 temporarily (temporarily locked) and then further fixing the electric unit 50 to the bolt 61.

Here, in the first stage of the second step, since the electric unit 50 is temporarily fixed, for example, the worker can release his / her hand from the electric unit 50, so that the work of screwing the bolt 61 It can be facilitated. 9 (d)) and the casing terminal 39 (Fig. 9 (d)) by the bolts 61 when the electric unit 50 receives an external force, (see Fig. 4 (d)).

In the illustrated example, the tread 323 and the bolt 61 are disposed on both sides in the longitudinal direction of the flange 58 formed in an approximately elliptical shape. With this arrangement, rotation of the electric unit (50) inserted into the casing (30) is suppressed. In addition, the flange 58 of the city has a notch 581 on its outer periphery. The notch 581 is dimensioned to receive the ridge portion 323. The rotation of the electric unit (50) is also suppressed by the notch (581).

10, when the electric unit 50 is fixed, the flange 58 and the handle 57 are exposed to the outside of the casing 30. As shown in Fig. More specifically, the handle 57 protrudes outward. As a result, when the electric unit 50 is pulled out, the operator can easily grasp the handle 57.

9 (d)) and the unit terminal 55 (see Fig. 9 (d)) above the insertion hole 311 of the casing 30 in the state in which the transmission unit 50 is fixed, (See Fig. 9 (d)). The drive unit 56 and the unit terminal 55 are prevented from being affected by water droplets or dust that may enter from between the insertion hole 311 and the electric unit 50. [ As described above, the transmission unit 50 has a waterproof and dustproof structure provided with a gasket 54 (see Fig. 8) and the like. Therefore, the gasket 54 or the like suppresses the influence of water droplets, dust, or the like on the constituent members inside the electric unit 50. [

    &Lt; Manual unit 70 &gt;

11 is an explanatory diagram of the passive unit 70. Fig.

Next, the manual unit 70 will be described with reference to Fig.

11, the passive unit 70, which is an example of the rotation mechanism and the abnormality control device, includes a cylindrical portion 71 and a plurality of support plates 71, which are provided along the axial direction of the cylindrical portion 71 and support the cylindrical portion 71, A fixing plate 74 fixed to the lower side of the first supporting plate 731 and a handle 74 to be operated by the operator are provided on the lower side of the first supporting plate 731 (the first supporting plate 731, the second supporting plate 733, the third supporting plate 735) A shaft portion 76 which is provided so as to penetrate through the cylindrical portion 71 and has one end connected to the handle portion 75 and a driving portion provided at the other end of the shaft portion 76 (Gear) 77). In the illustrated example, the passive unit 70 is formed of a resin such as polyoxymethylene (POM), but may be formed of a metal such as aluminum.

The central axis of the cylindrical portion 71 is arranged along the vertical direction. The cylindrical portion 71 in the illustrated example is fitted with both ends thereof by the first support plate 731 and the third support plate 735.

The support plate 73 (the first support plate 731, the second support plate 733, and the third support plate 735) is a substantially elliptical plate member. Through holes 7310, 7330 and 7350 are formed in each of the support plates 73, and a cylindrical portion 71 is inserted and fixed with an adhesive or the like.

The support plate 73 has a shape corresponding to the unit support portion 313 (see Fig. 3) of the casing 30. Fig. More specifically, the outer shape of the support plate 73 is a dimension corresponding to the outer shape of the unit body 51 of the electric unit 50 (see Fig. 8). Concretely, for example, the length in the longitudinal direction of the support plate 73 and the length in the longitudinal direction of the end surface of the unit main body 51 coincide with the length L1 (see Fig. 8). The manual unit 70 can be smoothly inserted into the unit support portion 313 of the casing 30 by fixing the support plate 73 and the cylindrical portion 71 as described above.

The electric unit 50 and the passive unit 70 can be exchanged by forming the portions of the electric unit 50 and the passive unit 70 that are inserted into the casing 30 in corresponding dimensions .

The third support plate 735 is provided with a mold hole 736 coaxial with the through hole 7350 on the upper side (to be described later in detail).

A through hole 740 is formed in the fixing plate 74, and a cylindrical portion 71 is inserted. This fixing plate 74 is a substantially elliptical plate member. The fixing plate 74 is larger than the supporting plate 73. The fixing plate 74 has a protruding portion 732 protruding from the lower side surface, a notch 734 formed on the outer periphery, and a through hole 737 penetrating through the fixing plate 74 in the thickness direction (up and down direction) .

The handle portion 75 is a substantially cylindrical member and is provided below the fixing plate 74. The handle portion 75 includes an outer circumferential groove 751 formed along the circumferential direction and a concave portion 753 provided circumferentially spaced apart from each other. The concave portion 753 is a portion for receiving a finger of the operator. In the handle portion 75 of the example shown in the drawing, three concave portions 753 are formed.

The shaft portion 76 is a substantially cylindrical member. The shaft portion 76 is provided so as to penetrate the cylindrical portion 71. The handle portion 75 is connected to the lower end portion and the driving portion 77 is connected to the upper end portion. Here, the shaft portion 76 is formed to have a longer dimension than the cylindrical portion 71. The shaft portion 76 is disposed between the handle portion 75 and the driving portion 77 so that the handle portion 75 and the driving portion 77 can move along the vertical direction, At a distance longer than that. That is, the shaft portion 76 is configured to have a clearance in the thrust direction with respect to the cylindrical portion 71.

The shaft portion 76 has an identification portion 761 (see Fig. 12 (a)) formed along the outer peripheral surface of the outer end portion. The identification portion 761 is a portion where the outer peripheral groove formed in the circumferential direction of the shaft portion 76 is colored.

The drive unit 77 is constructed in the same manner as the drive unit 56 (see Fig. 9 (a)) of the electric power unit 50 described above. Specifically, the driving portion 77 is a substantially cylindrical cylinder, and an external tooth 771 is formed on the outer circumferential surface of the driving body 77 to engage with the internal teeth 355 (see Fig. 5A) of the driven body 353. Further, a chamfer 773 is formed on the upper end (tip side) of the external tooth 771. The handle portion 75 and the driving portion 77 are examples of the manual rotation mechanism.

This manual unit 70 is inserted into the main body 31 (see Fig. 3) of the casing 30 so that the driving unit 77 provided at the tip of the manual unit 70 is engaged with the driven member 353 See Fig. 3). Then, when the worker rotates the handle portion 75, the force is transmitted through the shaft portion 76 and the drive portion 77, and the driven member 353 rotates. As the driven member 353 rotates, the connecting member 375 (see FIG. 1) moves, and as a result, the beam tilt angle of the antenna 1 is changed. That is, the passive unit 70 manually changes the beam tilt angle of the antenna 1.

The driving unit 77 enters into the opening 354 (see Fig. 5 (a)) of the driven member 353 so that the force received by the handle unit 75 is interlocked with the driven member 353, ). In other words, the driving unit 77 and the driven unit 353 function as a transmitting unit for transmitting the force received from the operator.

5 (a)) and the external teeth 771 are out of alignment with each other, the opening 354 (see Fig. 5 (a) The driven member 353 is manually rotated so that the internal teeth 355 and the external teeth 771 are engaged with each other.

    <Locking mechanism>

Figs. 12 (a) and 12 (b) are explanatory diagrams of the lock mechanism in the passive unit 70. Fig. More specifically, Fig. 12 (a) is a diagram showing the manual unit 70 in the rotation inhibition state, and Fig. 12 (b) is a diagram showing the manual unit 70 in the inhibition release state.

Next, the lock mechanism in the manual unit 70 will be described with reference to Figs. 12 (a) and 12 (b).

First, the manual unit 70 allows the operator to move the handle portion 75 in the vertical direction so that the rotation of the handle portion 75, the shaft portion 76, and the drive portion 77 is suppressed, that is, (See Fig. 12 (a)) and the state in which such inhibition of rotation is released, that is, the suppression cancel state (see Fig. 12 (b)). Therefore, the manual unit 70 can be locked by a simple and easy operation. By this locking, unintentional rotation of the handle portion 75 and the like can be suppressed.

Here, the rotation-inhibiting state and the suppression-canceling state will be further described.

12 (a), the handle portion 75, the shaft portion 76, and the drive portion 77 are moved downward (in a predetermined direction) in the rotation-inhibiting state. In this state, the driving portion 77 is engaged with the third supporting plate 735, and the rotation of the driving portion 77 is restricted by the third supporting plate 735 (details will be described later). The restricting mechanism 732 of the fixing plate 74 is interlocked with the outer circumferential groove 751 of the handle 75 so that the movement of the handle 75 in the up and down direction is restricted by the tongue 732 (Details will be described later).

On the other hand, as shown in Fig. 12 (b), the handle portion 75, the shaft portion 76, and the drive portion 77 are moved upward in the inhibition release state. In this state, the driving portion 77 is separated from the third supporting plate 735, and the third supporting plate 735 allows the driving portion 77 to rotate. The tread 732 is deviated from the outer peripheral groove 751 of the handle 75 and the tread 732 allows the handle 75 to move in the vertical direction.

Here, the driving portion 77, the third supporting plate 735, the fixing plate 74 and the handle portion 75 function as a locking mechanism of the passive unit 70.

The operation of the driving unit 77 and the third supporting plate 735, the operation of the tread 732 and the handle unit 75 of the fixing plate 74, the driving unit 77 and the driven member 353 )) Will be described in order.

    &Lt; Operation of driving part 77 and third supporting plate 735 &gt;

Figs. 13 (a) to 13 (c) are explanatory views of the operation of the driving unit 77 and the third supporting plate 735. Fig. 13A is a perspective view of the third support plate 735 viewed from above and FIG. 13B is a view showing the drive unit 77 and the third support plate 735 in the rotation-inhibited state, 13 (c) is a view showing the drive unit 77 and the third support plate 735 in the suppression released state.

Next, the operation of the driving unit 77 and the third supporting plate 735 will be described with reference to Figs. 13 (a) to 13 (c).

First, as shown in Fig. 13 (a), a mold (mold hole) 736, which is an example of a recess, is formed in the third support plate 735, which is an example of a regulating mechanism. The inner peripheral surface of the mold 736 has a shape in which it engages with the external teeth 771 (see FIG. 13 (b)) of the drive portion 77. In other words, an internal tooth engaging with the external teeth 771 of the drive portion 77 is formed on the inner peripheral surface of the mold 736. In the example shown in the drawing, eight convex portions (eight concave portions) are formed along the inner periphery of the mold 736. The mold 736 has an outer diameter larger than the through hole 7350 and the third support plate 735 has a toe abutting portion 738 which is a step between the mold 736 and the through hole 7350 .

Next, as shown in Fig. 13 (b), in the rotation limited state, the driven portion 77 moved downward is in a state of being inserted (fitted) into the mold 736. [ As a result, the rotation of the driving unit 77 is restricted. The driving portion 77 moving downward is brought into contact with the to-be-abutted portion 738 (see Fig. 13 (a)) of the third supporting plate 735. [ This prevents the driver 77 from being pulled downward.

On the other hand, as shown in Fig. 13 (c), in the suppression canceling state, the driving portion 77 moved upward does not engage with the mold 736. As a result, the rotation of the driving unit 77 is not restricted.

    Operation of the operation of the tongue 732 and the handle portion 75>

Figs. 14 (a) to 14 (c) are explanatory views of the operation of the ridge 732 and the handle portion 75. Fig. More specifically, Fig. 14 (a) is a side view of the ridge 732, Fig. 14 (b) is a view showing the ridge 732 and the handle portion 75 in the rotation- Depression releasing state 732 and handle portion 75. Fig.

Next, the operation of the roughened portion 732 and the handle portion 75 will be described with reference to Figs. 14 (a) to 14 (c).

First, as shown in Fig. 14 (a), the fixing plate 74 is provided with a tread 732 on the outer periphery of the through hole 740. As shown in Fig. The projection 732 has a top portion 7321 projecting toward the center of the through hole 740.

Next, as shown in Fig. 14 (b), in the state of restricting rotation, the protruding portion 732 is engaged with the outer circumferential groove 751 of the handle portion 75. More specifically, 7321 are drawn into the outer circumferential grooves 751. As a result, the movement of the handle portion 75 in the up and down direction is limited, and the rotation limiting state is prevented from being unintentionally released.

Specifically, in order for the handle portion 75 to move in the vertical direction, it is necessary to elastically deform the tread 732 until the portion 7321 moves to the outside of the outer peripheral groove 751. As the tread 732 is elastically deformed, the force applied to the movement of the handle 75 increases.

As shown in Fig. 14 (b), in the rotation limited state, the identification portion 761 becomes visible from the outside as the handle portion 75 moves downward. By recognizing the identification portion 761 by the operator, it is possible to grasp that the handle portion 75 is in the rotation restricted state, that is, the locked state.

On the other hand, as shown in Fig. 14C, the tread 732 does not interfere with the outer peripheral groove 751 of the handle portion 75 in the suppression canceled state. More specifically, the portion 7321 of the roughened portion 732 is present outside the outer circumferential groove 751. As a result, the movement of the handle portion 75 is not restricted. In the suppression canceling state, the identification portion 761 becomes in a state in which it can not be seen from the outside.

    &Lt; Operation of the operation of the driving unit 77 and the driven member 353 &gt;

15 is an explanatory diagram of the operation of the driving unit 77 and the driven member 353. Fig.

Next, the operation of the driving unit 77 and the driven member 353 will be described with reference to Fig. In Fig. 15, the drive unit 77 in the rotation-restricted state is shown by a solid line, and the drive unit 77 in the inhibition-release state is indicated by a broken line.

As described above, the rotation limiting state and the suppression canceling state are switched, whereby the driving unit 77 moves in the vertical direction. Here, as shown in Fig. 15, engagement of the drive unit 77 and the driven member 353 with each other is maintained in any of the rotation limited state and the suppression released state.

More specifically, the external teeth 771 of the drive portion 77 and the internal teeth 355 of the driven body 353 are engaged with each other (see arrow E1 in the figure) even in the rotation limited state. In other words, the chamfer 773 of the driving portion 77 and the trapezoidal serrations 357 do not become the same positions in the vertical direction in the rotation limited state.

Here, the external teeth 771 of the drive portion 77 and the internal teeth 355 of the driven body 353 are engaged with each other in the rotation limited state, that is, the state in which the drive portion 77 is inserted into the shape 736 The rotation of the driven member 353 through the driving unit 77 is also suppressed. The rotation of the driven member 353 is restricted so that the movement of the connecting member 375 (see Fig. 1) connected to the driven member 353 is restricted and consequently the beam tilt angle of the antenna 1 the deviation of the beam tilt angle is suppressed.

    &Lt; Fixed Mode of Manual Unit 70 &gt;

16 is an explanatory diagram of a fixing mode of the passive unit 70. Fig.

Next, the manner of fixing the passive unit 70 to the casing 30 with reference to Fig. 16 will be described.

The manual unit 70 is fixed in the same manner as the transmission unit 50 using the above-described Fig. Specifically, as shown in Fig. 16, the fixing plate 74 of the manual unit 70 is pressed by the tongue portion 323 and the bolt 61 so that the vertical direction of the manual unit 70 is fixed Is limited).

When the manual unit 70 is inserted into and fixed to the casing 30 after the tumbler portion 323 is resiliently deformed from the passage of the manual unit 70 and the tumbler portion 323 is fixed to the fixed plate 74 . In this state, the bolt 61 is fixed to the through hole 737 of the fixing plate 74. In other words, the fixing is performed in two stages of the tread 323 and the bolt 61.

16, the fixing plate 74 and the handle portion 75 are exposed (protruded) to the outside of the casing 30 when the manual unit 70 is fixed. As a result, when the manual unit 70 is pulled out, the operator can easily grip the holding plate 74 and the handle portion 75.

Here, the colors of the electromotive unit 50 and the passive unit 70 will be described with reference to Figs. 10 and 16. Fig.

Although not described in the foregoing, the electromotive unit 50 and the passive unit 70 are formed in different colors. For example, the flange 58 and the handle 57, which are portions exposed to the outside of the electric unit 50 inserted into the casing 30, are formed in black. On the other hand, the fixing plate 74 and the handle portion 75 which are exposed to the outside in the passive unit 70 inserted into the casing 30 are formed in white.

By forming the electromotive unit 50 and the passive unit 70 in different colors in this manner, it becomes possible to identify from which of the electromagnet 50 and the passive unit 70 is inserted into which casing 30 from the outside.

    <Modifications>

In the above description, the electric unit 50 and the passive unit 70 are exchanged. However, the electric units 50 and 70 may be replaced with each other.

In the case of using only the passive unit 70 in the casing 30, the casing terminal 39 may not be provided in the casing 30. [ The casing 30 that can insert the passive unit 70 and the electric unit 50 (or only the electric unit 50) can be provided by switching the configuration in which the casing terminal 39 is provided and the configuration in which the casing terminal 39 is not installed, And the manufacturing line of the casing 30 for inserting only the passive unit 70 can be made common.

Alternatively, the manual unit 70 may be temporarily used when exchanging the electric power from the electric power unit 50 to another electric power unit 50. Specifically, after the already mounted power transmission unit 50 is pulled out, the passive unit 70 is inserted into the casing 30. Then, the handle unit 75 of the manual unit 70 is operated to manually set the rotating body 35 (or the beam tilt angle) at a predetermined angle (for example, zero point) The manual unit 70 may be pulled out and another power transmission unit 50 may be inserted. In other words, the passive unit 70 may be used as a jig.

In the above description, the drive units 56 and 77 are provided at the ends of the electromotive unit 50 and the passive unit 70, respectively, but the present invention is not limited thereto. It may be provided at any position as long as the movable unit 50 and the manual unit 70 are engaged with the driven member 353 in accordance with the insertion of the manual unit 70 into the casing 30. [

In the above description, the transmission unit 50 and the manual unit 70 are fixed by the protrusion 323 and the bolt 61, but the present invention is not limited to this. The transmission unit 50 and the manual unit 70 may be restricted from moving in the vertical direction and may be fixed by any one of the trough 323 and the bolt 61, for example. It is also possible to use a spring (not shown) for buckling the electric unit 50 and the passive unit 70 upward instead of the bolt 61.

In the above description, the configuration in which the ridge 732 of the fixing plate 74 is caught in the outer peripheral groove 751 of the handle portion 75 has been described, but the present invention is not limited to this. If the movement of the handle portion 75 in the up and down direction is restricted, other configurations such as a mechanism for restricting the movement of the tread portion 732 of the holding plate 74 by engaging with the lower end surface of the handle portion 75 may be limited There is no.

In the above description, it is described that the shape of the hole 736 includes eight protrusions on the inner circumferential surface, but it may be a shape that changes its outer shape depending on the angle with respect to the center of the hole, that is, a shape other than a circular shape. Further, as described above, by providing a plurality of projections having the same configuration in the circumferential direction, the amount by which the drive section 77 is rotated until the drive section 77 is fitted (fitted) into the shape 736 is reduced.

In the above description, it has been described that the handle portion 75 is moved to the lower side to be in the rotation inhibition state, and the handle portion 75 moves to the upper side to be in the inhibition release state. In this configuration, if the handle portion 75 (the drive portion 77) is moved by its own weight, the rotation restraining state is established and the lock is engaged. Therefore, unintentional rotation of the handle portion 75 can be suppressed when the handle portion 75 is moved downward by, for example, receiving external vibration. The direction of the movement is not limited to this. The handle portion 75 may be configured to be in the rotation inhibiting state by moving in the other direction such as moving upward or moving in the horizontal direction.

17 is an explanatory diagram of the composite unit 90. Fig.

18 is a view of the complex unit 90 viewed from the outside in the outer direction. In Fig. 18, a part of the unit body 91 is shown in a cut state.

In the above description, the transmission unit 50 and the manual unit 70 are alternatively inserted into the casing 30. However, the present invention is not limited to this.

For example, as shown in Fig. 17, the composite unit 90, which is an example of the abnormality control device, may be inserted into the casing 30.

Here, the motor gear 941 is a substantially cylindrical member. The motor gear 941 includes a shaft hole 941a formed on the upper end surface thereof for receiving the motor shaft 921 and an outer peripheral portion (serration) 941b formed on the lower outer peripheral surface, And a pin hole 941c into which a pin PN for fixing the shaft 921 is inserted.

Incidentally, in the present embodiment, the position of the pull clutch 97 and the motor clutch 943 in the up-and-down direction is movable.

As shown in Fig. 18, the handle clutch 97 and the motor clutch 943 are provided so as to be interdigitated with each other.

More specifically, the large-diameter portion 975 of the handle clutch 97 is installed such that both sides of the large-diameter portion 975 in the up-down direction are sandwiched by the outer-diameter portion 943b and the large-diameter portion 943d of the motor clutch 943. In other words, the outer diameter portion 943b and the large diameter portion 943d of the motor clutch 943 are provided in the movement route of the large-diameter portion 975.

Then, the handle clutch 97 is moved in the up and down direction by the operator. With the movement of the handle clutch 97, the motor clutch 943 also moves in the vertical direction.

It is to be noted that a state in which the drive portion 96 is rotated by the motor 92 in accordance with the movement of the handle clutch 97 and the motor clutch 943 in the vertical direction And a state in which the drive unit 96 is rotated by the drive of the handle clutch 97 (hereinafter, this may be referred to as a manual state) is switched.

In addition, the handle clutch 97 in this embodiment is an operating portion that is rotated by an operator in order to supply a driving force to the driving portion 96 in a manual state, 2 sun), as a member serving also as an operation unit.

    <Switching between power and manual states>

Figs. 20 (a) and 20 (b) are diagrams for explaining an electric state and a manual state. Fig. More specifically, Fig. 20 (a) shows the arrangement around the clutch clutch 97 and the motor clutch 943 in the transmission state, Fig. 20 (b) shows the arrangement of the clutch clutch 97 and motor And the arrangement around the clutch 943 is shown.

Next, the electric state and the manual state will be described with reference to Figs. 20 (a) and 20 (b).

First, the electric state will be described in detail with reference to Fig. 20 (a).

In the state shown in Fig. 20 (a), the handle clutch 97 and the motor clutch 943 are disposed on the lower side. When the handle clutch 97 is disposed on the lower side, the handle clutch 97 is separated from the drive gear 945. That is, the inner tooth portion 979 of the handle clutch 97 is not engaged with the second tooth portion 945c of the drive gear 945. On the other hand, the outer tooth portion 943b of the motor clutch 943 is engaged with the second tooth portion 945c of the drive gear 945.

As a result, the output of the motor 92 is transmitted to the motor clutch 943. The output transmitted from the motor clutch 943 to the drive gear 945 rotates the drive unit 96 (see FIG. 18) through the drive shaft 947.

On the other hand, the handle clutch 97 is free from the driving gear 945 and is in a free state. Therefore, even if the operator turns the knob clutch 97 in this rolling state, the knob clutch 97 revolves. Then, the rotational force of the handle clutch 97 is not transmitted to the driving portion 96 (see Fig. 18).

Next, the manual state will be described with reference to Fig. 20 (b).

In the state shown in Fig. 20 (b), the handle clutch 97 and the motor clutch 943 are disposed on the upper side. When the handle clutch 97 is disposed on the upper side, the inner tooth portion 979 of the handle clutch 97 is engaged with the second tooth portion 945c of the drive gear 945. On the other hand, the outer tooth portion 943b of the motor clutch 943 is not engaged with the second tooth portion 945c of the drive gear 945.

That is, the motor clutch 943 is free from the driving gear 945 and is in a free state. Therefore, even if the motor 92 is driven, the motor gear 941 and the motor clutch 943 rotate. The output of the motor 92 is not transmitted to the driver 96 (see FIG. 18).

On the other hand, the output transmitted from the handle clutch 97 to the drive gear 945 rotates the drive portion 96 (see Fig. 18) through the drive shaft 947. [

As the handle clutch 97 and the motor clutch 943 are moved in the vertical direction in this manner, the handle clutch 97 and the drive gear 945 are switched to the engaged state, and the motor clutch 943 and the drive gear 945 are engaged with each other. In other words, an object to be engaged with the drive gear 945 is switched between the handle clutch 97 and the motor clutch 943 by the movement of the handle clutch 97 in the vertical direction.

In other words, by moving the handle clutch 97 in a predetermined direction, an object to be engaged with the drive gear 945 is switched between the handle clutch 97 and the motor clutch 943.

In the illustrated example, the internal gear portion 943a of the motor clutch 943 is engaged with the external gear portion 941b of the motor gear 941 irrespective of the vertical movement of the motor clutch 943 State is maintained. In other words, even when the motor clutch 943 is moved downward (see Fig. 20A), the internal gear portion 943a of the motor clutch 943 and the external gear portion 941b of the motor gear 941 are connected to each other Do not leave. This makes it possible to prevent the gears (the internal gear portion 943a of the motor clutch 943 and the external gear portion 941b of the motor gear 941) from being brought into a state in which they are not engaged with each other.

In the illustrated example, regardless of whether the motor clutch 943 is moved in the vertical or up-and-down direction, the potentiometer 93 (see FIG. 18) (See Fig. 18) through a first potentiometer gear 951, a first potentiometer gear 949, a drive gear 945, and a drive shaft 947. [ Therefore, the potentiometer 93 can grasp the rotational angle of the driver 96 in any of the manual state and the powered state.

More specifically, in the example shown in the drawing, the state in which the potentiometer 93 is connected to the drive unit 96 (see FIG. 18) is maintained even during the switching between the manual state and the powered state. Therefore, the potentiometer 93 can more accurately grasp the rotation angle of the driving unit 96, as compared with the embodiment in which the connected state is not maintained unlike the example shown in the drawing.

18, since the potentiometer 93 of the combined unit 90 operates with a program common to the potentiometer 53 of the electromotive unit 50 shown in Fig. 8, the drive unit 96 (see Fig. 18) And the gear reduction ratio of the potentiometer 53 (see FIG. 8) to the drive unit 56 (see FIG.

In the example shown in the drawing, an operator who rotates the drive unit 96 (see FIG. 18) in the manual state can grasp the amount of rotation of the drive unit 96 by the slide gauge 373 (see FIG. 6).

Here, in the example shown in the drawing, the worker moves the handle 973 in the vertical direction and rotates the handle 973 while holding the handle 973 of the handle clutch 97. This makes it possible to move the grip portion 973 in the vertical direction while rotating, for example.

Therefore, depending on the relative angles of the handle clutch 97 and the drive gear 945, for example, when the handle 973 is moved in the up-and-down direction, The teeth of the second tooth portion 945c in the driving gear 945 may hit each other. In this case, by rotating the knob portion 973, the inner tooth portion 979 and the second tooth portion 945c can be engaged with each other.

    &Lt; Switching operation from electric state to manual state &gt;

21 is a view for explaining the switching operation from the electric state to the manual state.

Next, the switching operation from the motoring state to the manual state will be described with reference to Fig.

First, as shown in Fig. 21 (a), it is assumed that the composite unit 90 is in the rolling state. The motor clutch 943 is disposed on the lower side (on the right side in the figure) and the motor clutch 943 is engaged with the drive gear 945 while the handle clutch 97 is engaged with the drive gear 945 to be.

21 (b), when the operator pushes the handle clutch 97 to the upper side (the left side in the drawing), the large-diameter portion 975 of the handle clutch 97 is moved to the outside of the motor clutch 943 And pushes the tooth portion 943b upward. As a result, the motor clutch 943 is moved upward. Then, the inner tooth portion 979 of the handle clutch 97 starts to engage with the second tooth portion 945c of the drive gear 945.

The larger diameter portion 975 of the handle clutch 97 pushes the outer peripheral portion 943b of the motor clutch 943 upward as the motor clutch 943 is pushed upward.

Then, as shown in Fig. 21 (c), the motor clutch 943 is pushed further into the upper side (the left side in the drawing). The engagement width of the inner tooth portion 979 of the handle clutch 97 and the second tooth portion 945c of the drive gear 945 is increased. Also, the large-diameter portion 975 of the handle clutch 97 pushes the motor clutch 943 further upward.

Then, as shown in Fig. 21 (d), when the handle clutch 97 completes the movement to the upper side, the composite unit 90 is in the manual state. That is, while the handle clutch 97 is engaged with the drive gear 945, the motor clutch 943 is in the state of not meshing with the drive gear 945.

    &Lt; Switching operation from manual state to electric state &gt;

22 is a diagram for explaining a switching operation from a manual state to a motorized state.

Next, the switching operation from the manual state to the electric state will be described with reference to Fig.

22 (a), it is assumed that the hybrid unit 90 is in a manual state. Namely, the motor clutch 943 is disposed on the upper side (left side in the figure), and the knob clutch 97 is connected to the drive gear 945 While the motor clutch 943 is not engaged with the drive gear 945. [

22 (b), the large-diameter portion 975 of the handle clutch 97 is pulled out of the motor clutch 943 by pulling the handle clutch 97 downward (right side in the drawing) And presses the large-diameter portion 943d downward. Thereby, the motor clutch 943 moves downward. The outer tooth portion 943b of the motor clutch 943 starts to engage with the second tooth portion 945c of the drive gear 945. [

The large diameter portion 975 of the handle clutch 97 pushes the large diameter portion 943d of the motor clutch 943 downwardly as the motor clutch 943 is drawn out downward.

Then, as shown in Fig. 22 (c), the motor clutch 943 is further pulled downward (right side in the figure). The engagement width of the outer tooth portion 943b of the motor clutch 943 and the second tooth portion 945c of the drive gear 945 is increased. Also, the large-diameter portion 975 of the handle clutch 97 pushes the motor clutch 943 further downward.

Then, as shown in Fig. 22 (d), when the knob clutch 97 completes the movement to the lower side, the composite unit 90 becomes in the electric state. That is, while the motor clutch 943 is engaged with the drive gear 945, the handle clutch 97 is not engaged with the drive gear 945.

Incidentally, in the example shown in the drawing, either the manual state or the electric state is alternatively selected by switching the position of the knob clutch 97 in the vertical direction. Therefore, neither the manual clutch 97 nor the motor 92, which is in a state of being driven by both the clutch clutch 97 and the motor 92, which is a manual state and a power transmission state, It is avoided that the vehicle is not driven.

In the illustrated example, the motor 92 is detached from the handle clutch 97 both in the manual state and in the powered state.

As a result, when the operator turns the knob clutch 97 in the manual state, it becomes unnecessary to apply a rotational force for turning the motor 92. [ As a result, the operability of the clutch clutch 97 is improved. By causing the motor 92 to rotate in the reverse direction (back drive), for example, an electromotive force is generated in the motor 92 and damage to the commutator (not shown) provided in the motor 92 is suppressed.

In addition, rotation of the handle clutch 97 is suppressed when the motor 92 is driven in the power transmission state. In addition, even when the handle clutch 97 receives an external force by an operator or the like when the motor 92 is driven in the power running state, the load due to the external force is restrained from being applied to the motor 92.

In the example shown in the drawing, the handle clutch 97 is urged downward by its own weight, and the leaf spring 955 (see Fig. 18), which is an example of the urging mechanism, In the opposite direction). Therefore, in the illustrated example, when the handle clutch 97 is not receiving an external force, it is brought into the electric state. Further, when the handle clutch 97 is subjected to a force in the direction of upward movement, the transmission state is switched to the manual state.

Here, in the manual state, in order to operate the knob clutch 97, the operator is indispensable to the place where the composite unit 90 is installed. On the other hand, in the motorized state, a worker is not required in a place where the complex unit 90 is installed. In addition, in a state in which there is no operator, the necessity of setting the manual state is also low.

Therefore, when the handle clutch 97 is not receiving an external force as in the example shown in the drawing, it is in an electric state. Thus, even if the operator forgets to return the handle clutch 97 from the manual state to the powering state, the motor 92 can rotate the drive unit 96, for example.

In addition, here, the switching between the manual state and the electric state accompanied by the operation (pushing or pulling forward) of the handle clutch 97 has been described. However, the present invention is not limited to this, and the knob clutch 97 may be moved by the self weight of the handle clutch 97 or the biasing force of the leaf spring 955 to switch between the manual state and the electric state.

    <Modifications>

For example, the motor clutch 943 may be in a manual state when the motor clutch 943 is disposed on the lower side, and may be in an electric state when the motor clutch 943 is disposed on the upper side. Similarly, when the handle clutch 97 is disposed at the lower side, it may be in the manual state, and when the handle clutch 97 is disposed at the upper side, it may be in the electric state.

In the above description, it is explained that the handle clutch 97 is urged downward by the leaf spring 955, but the present invention is not limited to this.

For example, the handle clutch 97 may be biased upward by the leaf spring 955. In addition to the plate spring 955, other elastic members such as coil springs may be used. Alternatively, a configuration in which the leaf spring 955 is not used may be employed.

The arrangement and direction of the clutch body 971 of the motor 92, the potentiometer 93, and the like in the above description are not particularly limited.

In the above description, the motor 92 is detached from the handle clutch 97 in the manual state. However, the motor 92 may be configured so as not to be detached from the handle clutch 97. That is, a configuration in which, in the manual state, a force by which an operator turns the pull clutch 97 is transmitted to the motor 92.

In the above description, the antenna 1 transmits the radio wave. However, the antenna 1 receives the radio wave due to the reversibility of the antenna 1. In the case of receiving radio waves, for example, it is sufficient to reverse the flow of the signal with the transmission signal as the reception signal.
