Description

  The present invention utilizes a relative movement between a pair of cables by connecting an operation part such as an operation knob provided on an air conditioning control panel and an operated part such as a damper provided on an air conditioning duct with a pair of cables. The present invention also relates to a remote control device for transmitting the rotational motion of the operation unit to the operated portion as rotational motion.

  This type of remote control device is mounted on an automobile and widely used for air conditioning control. For example, Patent Document 1 discloses a remote control device for rotating a damper with a damper provided in an air conditioning duct as an operated portion. The remote control device disclosed in Patent Document 1 is provided with a pulley connected to a damper shaft in a non-rotating state, and the ends of a pair of cables are connected and fixed to the pulley. A pair of cables are integrally held by a double-wire type outer cable until reaching the pulley, wound around the outer peripheral surface of the pulley so as to surround the pulley, and both ends of the cable end are fixed to the pulley. . Accordingly, the pulley can be rotated by relatively moving the pair of cables, and the angle of the damper that rotates integrally with the pulley can be adjusted. Therefore, if a remote control device of the same kind is also provided on the side of the operation knob provided on the air conditioning control panel, the rotary motion of the control knob can be transmitted to the damper as a rotary motion. Angle adjustment is possible.

  A first embodiment will be described with reference to FIGS.

  The remote control device 11 according to the present embodiment transmits the rotation of the operation knob to the damper using the operation knob provided on the air conditioning control panel of the automobile as the operation portion and the damper provided in the air conditioning duct as the operated portion. Used for rotating the damper (all not shown).

  FIG. 1A is a rear view of the entire apparatus showing the case where the rotating body 201 is in the housed state, and FIG. 1B is the case where the rotating body 201 is in the used state. FIG. 2 is a vertical side view of the entire apparatus showing a case where the rotating body 201 is in the housed state. The remote control device 11 according to the present embodiment is generally formed by similarly holding an elongated rotating body 201 rotatably on an elongated base 101. As an example, the base 101 and the rotating body 201 are both formed of a member having an elastic restoring force such as a resin.

  The base 101 includes a cable holding hole 102 for storing and holding an outer cable 52 that slidably holds a pair of cables 51 at one end, and a holding groove 103 for holding the rotating body 201 at the other end. The cable holding hole 102 has a cable hole 102a at the bottom thereof. The cable hole 102 a is formed in a size that allows the pair of cables 51 drawn from the outer cable 52 held in the cable holding hole 102 to be inserted. The tip of the cable 51 inserted through the cable hole 102 a is directed toward the holding groove 103. The cable 51 is slidable in the outer cable 52. Therefore, the base 101 holds the cable 51 so as to be displaceable in the longitudinal direction. Such a base 101 has its bottom surface offset in a concave shape, and this offset portion is used as a space for arranging the rotating body 201.

  The rotating body 201 is formed by a rectangular flat arm member 202. The arm member 202 is formed to have substantially the same width as that of the base 101, and the four corners thereof are rounded off. Such a rotating body 201 has a connecting body 203 positioned at the central portion of the arm member 202. The connecting body 203 has a connecting hole 204 at the center thereof, and is a member protruding in a cylindrical shape from the flat surface of the arm member 202 around the connecting hole 204. A fitting groove 205 is formed on the outer peripheral surface of the connecting body 203. ing. The fitting groove 205 is formed with a size that fits into the holding groove 103 formed in the base 101. Therefore, the rotating body 201 is disposed at the offset portion on the lower surface side of the base 101 and is attached to the base 101 so that the fitting groove 205 of the coupling body 203 is fitted into the holding groove 103 of the base 101. Due to such a structure, the rotating body 201 is slidably movable in the holding groove 103 and is rotatable in the holding groove 103. Since the holding groove 103 is formed along the displacement direction of the cable 51 held by the base 101, the rotating body 201 is movable along the displacement direction of the cable 51. Also, the rotating body 201 expands the arm member 202 from both sides of the base 101 in a direction that is not parallel to the displacement direction of the cable 51 with the cable 51 interposed therebetween. At this time, the arm member 202 gradually increases its angle from a small angle slightly non-parallel to the displacement direction of the cable 51 according to the rotation of the rotating body 201.

  The cable 51 held on the base 101 is connected and fixed to the rotating body 201. The rotating body 201 has hooking grooves 206 on both ends of the arm member 202 that expands from both sides of the base 101 by the rotation, and has a fixing hole 207 at the center side end. The pair of cables 51 drawn from the outer cable 52 and passing through the cable hole 102a toward the holding groove 103 have their cable ends 53 bound to the crimping portion 54. Therefore, the caulking portion 54 of the pair of cables 51 is press-fitted into the fixing hole 207 in a state where each of the cables 51 is hooked in the hooking groove 206. Thus, the pair of cables 51 are connected and fixed to the rotating body 201. The pair of hooking grooves 206 and the fixing holes 207 form a pair of cable fixing portions CH that respectively connect and fix one end sides of the pair of cables 51 at two positions extending from both sides of the base portion 101.

  The base 101 and the rotating body 201 are provided with a rotating body holding mechanism RH that fixes the position of the rotating body 201 at a rotational position where the arm member 202 does not expand from the base 101. As the rotating body holding mechanism RH, the base 101 is formed with a substantially hemispherical holding convex portion 104 and the rotating body 201 is formed with a holding hole 208. When the rotating body 201 is positioned at a position where it overlaps with the base 101, in other words, at a position where the longitudinal directions of the rotating body 201 coincide with each other, the holding convex portion 104 of the base 101 and the holding hole 208 of the rotating body 201 are fitted together. Rotation is regulated. In this state, the rotating body 201 is in a state along the displacement direction of the cable 51 held by the base 101. Here, for convenience, this state is referred to as a “storage state”.

  The base 101 has a holding projection 104 formed on a thin tongue-shaped elastic deformation body 105. Refer to FIG. 1B for the shape of the tongue piece and FIG. 2 for the thin shape. Due to such a structure, when the holding convex portion 104 and the holding hole 208 are fitted to each other and the rotating body 201 fixed to the base 101 is rotated by applying an external force, the elastic deformable body 105 is inclined to the slope of the holding convex portion 104. And the fitting state between the holding hole 208 and the holding convex portion 104 is released. As a result, the rotating body 201 is rotatable and expands from the base 101 in a direction that is not parallel to the displacement direction of the cable 51. Here, for convenience, this state is referred to as a “use state”.

  FIG. 3 is a front view of the entire apparatus showing the rotation state of the rotator 201. In the state of use shown in FIG. 1B, when one of the pair of cables 51 is pulled on the end side that is not coupled and fixed to the rotating body 201, the arm member 202 of the rotating body 201 is pulled by the cable 51 and rotated. In response to this, the other cable 51 is drawn. Therefore, when the pair of cables 51 are moved in opposite directions, the arm member 202 of the rotating body 201 can be rotated as shown in FIG.

  Further, as shown in FIGS. 1A, 1B, and 2, the base 101 has a cylindrical positioning pin 106 formed on the lower surface thereof. The arrangement position is in the vicinity of the cable holding hole 102. The positioning pin 106 is used for positioning when the remote operation device 11 is attached to a remote operation device mounting portion 301 (see FIG. 3) described later.

  FIG. 4 is a front view showing the remote operation device mounting portion 301 disposed in the vicinity of the damper which is the operated portion. The remote operation device mounting portion 301 is provided with a pedestal portion 303, an operation portion 304, and a pair of fixed claw portions 305 on a flat substrate 302.

  FIG. 5 is a longitudinal side view of the remote control device mounting unit 301 with the remote control device 11 attached thereto. In FIG. 5, the remote control device 11 is shown in a section taken along line BB in FIG. 3. The pedestal portion 303 protrudes from the substrate 302 and holds the base portion 101 of the remote operation device 11. In order to position the base 101, the pedestal 303 is formed with a positioning hole 306 for fitting a positioning pin 106 provided on the lower surface of the base 101.

  The operation unit 304 includes an operation shaft 307 that is rotatably attached to the substrate 302. The operating shaft 307 is connected to a rotating shaft of a damper provided in an air conditioning duct (not shown). Therefore, if the operating shaft 307 rotates, the damper also rotates. Such an operating part 304 has an operating lever 308 formed integrally with the operating shaft 307. The actuating lever 308 is formed in the same shape and size as the arm member 202 of the rotating body 201, and can hold the arm member 202 in an overlapping manner. In order to hold the arm member 202, the operating lever 308 is formed with a fitting convex portion 309 that fits into the holding hole 208 formed in the arm member 202 that is overlapped.

  Further, the operating part 304 has a connecting pin 310 that is coaxial with the operating shaft 307 and fits into a connecting hole 204 formed in the connecting body 203 of the rotating body 201.

  The fixed claw portions 305 are a pair of members that sandwich and hold both side portions of the base portion 101 of the remote control device 11 attached to the pedestal portion 303 and the operating portion 304. Such a fixed claw portion 305 is formed by providing a claw portion 312 at the distal end portion of a pair of elastic pieces 311 which are vertically arranged facing each other from the substrate 302. The facing distance between the pair of elastic pieces 311 is formed to be substantially the same width as the width of the base portion 101, and the facing distance between the pair of claw portions 312 is formed to be narrower than the width of the base portion 101.

  In such a configuration, the remote operation device 11 can be detachably attached to the remote operation device mounting portion 301 using the pedestal portion 303, the operation portion 304, and the fixed claw portion 305. That is, the remote operation device 11 is attached to the remote operation device mounting portion 301 by holding the base portion 101 in the pedestal portion 303 and holding the rotating body 201 in the operation portion 304. At this time, the base portion 101 is positioned by fitting the positioning pin 106 into the positioning hole 306 of the pedestal portion 303. The rotating body 201 is attached with the arm member 202 overlapped with the operation lever 308 in a state where the connection pin 310 of the operation unit 304 is fitted in the connection hole 204. Thereby, the fitting convex part 309 of the operating lever 308 is fitted into the holding hole 208 of the arm member 202, and the rotating body 201 is integrated with the operating lever 308. At this time, the base portion 101 of the remote operation device 11 is placed between the pair of elastic pieces 311 so as to expand the pair of claw portions 312 in the fixed claw portion 305, and is prevented from being detached by the claw portions 312. Thus, the remote operation device 11 is attached to the remote operation device mounting portion 301.

  The remote operation device 11 attached to the remote operation device mounting portion 301 can rotate the rotating body 201 by moving the pair of cables 51 in opposite directions, and the rotation of the rotating body 201 is caused to move the operating portion 304. To a damper (not shown) provided in the air conditioning duct. Therefore, the same remote operation device 11 as the remote operation device 11 is also connected to the end opposite to the cable end 53 which is one end side of the pair of cables 51 connected and fixed to the rotating body 201. By connecting 11 to a drive unit (not shown), the rotational motion of the drive unit can be converted into the rotational motion of a damper, which is a driven unit, and transmitted. The remote control device 11 connected to the end of the pair of cables 51 opposite to the cable end 53 is not shown, but for convenience, the base 101 included in the remote control device 11 is a second base, The rotating body 201 is referred to as a second rotating body. In implementation, the second rotating body is connected to the rotating shaft (all not shown) of the operation knob provided on the air conditioning control panel of the automobile. Accordingly, when the operation knob is rotated, the second rotating body is also rotated, whereby the pair of cables 51 are moved in opposite directions within the outer cable 52. Then, as shown in FIG. 3, in the remote control device 11 connected to a damper (not shown) as a driven part, one cable 51 is pulled into the outer cable 52, and the other cable 51 is connected to the outer cable 52. By being pulled out from the cable 52, the rotating body 201 rotates. When the rotating body 201 rotates, the operation unit 304 also rotates, and the damper also rotates through the operation shaft 307. Thus, by rotating the operation knob provided in the air conditioning control panel of the automobile, the damper provided in the air conditioning duct can be rotated and adjusted.

  Here, an operation procedure for connecting the remote control device 11 to a damper (all not shown) as a driven part provided in the air conditioning duct will be described. First, a remote control device 11 connected to a damper is inserted into an opening (not shown) for attaching an air conditioning control panel of an automobile. At this time, the rotating body 201 is kept in a storage state as shown in FIG. Next, in order to guide the remote control device 11 inserted into the opening to the position of a damper provided in the air conditioning duct, the remote control device 11 is passed through spaces between various structures. In this case, since the space between the various structures through which the remote control device 11 passes is generally narrow, the remote control device 11 must be passed through the narrow space. On the other hand, the remote control device 11 in which the rotating body 201 is stored is easily elongated even in a narrow space because the base 101 and the rotating body 201 overlap and take an elongated shape. Therefore, the workability can be improved. Moreover, the rotating body 201 in the housed state maintains the state held by the base 101 by the rotating body holding mechanism RH. Accordingly, it is possible to prevent the occurrence of an accident in which the rotating body 201 is unexpectedly rotated and caught on some structure during the transport of the remote control device 11.

  When the remote control device 11 is carried to the installation position of the remote control device mounting portion 301 located in the vicinity of the damper, the rotating body 201 is rotated with respect to the base portion 101 to match the angle of the operation lever 308 in the operation portion 304. In this state, the remote operation device 11 can be attached to the remote operation device mounting portion 301 as described above.

  Here, in the present embodiment, the rotating portion 201 is formed by an arm member whose central portion is rotatably held by the base 101 and whose both end portions expand from both sides of the base 101 by rotating with respect to the base 101. . As a result, the overall structure can be simplified, and as a result, the manufacturing cost can be reduced. In particular, due to the structure of the rotating body 201, the flat arm member 202 can be easily adopted as in the present embodiment, and the structure can be further simplified and the manufacturing cost can be reduced.

  Further, in the present embodiment, when the rotating body 201 is in the housed state, one cable 51 is in a state avoiding the connecting body 203 (see FIG. 1A). For this reason, the total length of the pair of cables 51 exposed from the outer cable 52 when the rotating body 201 is in the housed state (see FIG. 1A) is the same as when the rotating body 201 is in use (FIG. 1 ( It becomes longer than the total length of the pair of cables 51 exposed from the outer cable 52 of b). Therefore, in the first embodiment, the connecting body 203 is slidable in the holding groove 103 so that the cable 51 does not become slack even when the rotating body 201 is in use. ing. That is, when the rotating body 201 is in use, it is possible to prevent slack in the cable 51 by moving the connecting body 203 to the inlet side of the holding groove 103. The remote operation device mounting portion 301 determines the dimensions of each portion so that the remote operation device 11 can be mounted in a state where the cable 51 is not slack.

  A second embodiment will be described with reference to FIGS. FIG. 6A is a rear view of the entire apparatus showing the case where the rotating body 251 is in the housed state and FIG. 6B is the case where the rotating body 251 is in the used state. FIG. 7 is a longitudinal side view of the entire apparatus. The remote control device 21 of the present embodiment is generally formed by holding a rotating body 251 on an elongated base portion 151. Both the base 151 and the rotating body 251 are formed of a member having an elastic restoring force such as a resin as an example.

  The base 151 includes a cable holding hole 152 that holds the outer cable 52 that holds the pair of cables 51 in a slidable state at one end, and a holding groove 153 that holds the rotating body 251 at the other end. The cable holding hole 152 holds the outer cable 52 by press fitting. The tip of the cable 51 protruding from the end of the outer cable 52 is directed toward the holding groove 153. Since the cable 51 is slidable in the outer cable 52, the base 151 holds the cable 51 so as to be displaceable in the longitudinal direction. Such a base 151 has its bottom surface offset in a concave shape, and this offset portion is used as a space for arranging the rotating body 251.

  The rotating body 251 has a pair of arm members 252. The pair of arm members 252 are both formed in an arc shape and are rotatably connected by a connecting portion 253. The connecting portion 253 has a connecting hole 254, and is rotatably attached to the base portion 151 through the connecting hole 254. In FIG. 6A, the connecting portion 253 of the lower arm member 252 is offset from the main body of the arm member 252 to the base AD102 side of the adapter AD101 by the thickness of the arm member 252 along the rotation axis direction. Is formed.

  That is, the adapter 151 of the rotating body 251 is slidably provided in the holding groove 153 of the base 151. The adapter AD101 includes a base AD102 that slides in contact with the base 151, and has a connecting body AD103 that fits in the holding groove 153 on one end side, and a boss AD104 that stands on the other end. The coupling body AD103 is a cylindrical member having a fitting groove AD105 fitted in the holding groove 153 on the outer peripheral surface, and a coupling hole AD106 is formed in the center portion thereof. The connection hole AD106 has a flat portion AD106a in part (see FIGS. 6A and 6B) and is formed in a shape that is not a perfect circle.

  The holding groove 153 formed in the base 151 extends from the end opposite to the cable holding hole 152 toward the cable holding hole 152. Accordingly, the adapter AD101 is slidable in the displacement direction of the cable 51 in which the outer cable 52 is held in the cable holding hole 152.

  The boss AD104 is formed of three elastic pieces AD107, and has a shape that forms a virtual cylinder when these elastic pieces AD107 are connected. Each of the elastic pieces AD107 is provided with a claw AD108 at the tip. All of these claw portions AD108 face the outer peripheral surface side. The diameter of a virtual cylinder connecting the individual elastic pieces AD107 is formed to be substantially equal to the inner diameter of the connecting hole 254 formed in the connecting portion 253 of the arm member 252. Therefore, the connecting holes 254 of the connecting portions 253 of the two arm members 252 are respectively inserted into the boss AD104, and the arm members 252 are attached. Here, the length excluding the claw portion AD108 of each elastic piece AD107 is formed substantially equal to the length obtained by adding the thickness of the two arm members 252. Therefore, the elastic piece AD107 is bent in the process of inserting the connecting portion 253 into the boss AD104, and when the insertion is completed, the bent elastic piece AD107 is restored to the original shape. Accordingly, the claw portion AD108 prevents the coupling portion 253 from coming off, and the rotating body 251 is rotatably attached to the adapter AD101. In this state, since the pair of arm members 252 are rotatably connected by the connecting portion 253, the narrowed state as shown in FIG. It can also be in an open state. The pair of arm members 252 are joined to each other in the narrowed state as shown in FIG. 6 (a), and large in the widened state as shown in FIG. 6 (b). The mouth is open. For convenience, the state illustrated in FIG. 6A is referred to as a “storing state”, and the state illustrated in FIG. 6B is referred to as a “use state”.

  The base 151 is provided with a rotating body holding mechanism RH ′ that fixes the position of the arm member 252 in the retracted state. As the rotating body holding mechanism RH ′, a pair of holding convex portions 155 are formed to protrude from the base portion 151. When the arm member 252 is in the retracted state, the pair of holding convex portions 155 engages with the outer edge of each arm member 252 to restrict the movement of the arm member 252 to the use state.

  The base 151 forms a substantially hemispherical holding convex portion 155 on a thin tongue-shaped elastic deformation body 156. Due to such a structure, when the holding convex portion 155 and the outer edge portion of the arm member 252 are engaged and the arm member 252 fixed to the base portion 151 is rotated by applying a predetermined external force or more, the elastic deformation body 156 is elastically deformed in the direction away from the arm member 252 along the slope of the holding convex portion 155, and the fitting state between the holding convex portion 155 and the outer edge portion of the arm member 252 is released. Thereby, the arm member 252 becomes rotatable and can be moved to a use state.

  FIG. 8 is a perspective view showing the structure of the cable fixing portion 255 that the arm member 252 of the rotating body 251 has. The pair of arm members 252 has a cable fixing portion 255 at the tip thereof. The cable fixing portion 255 includes an end holding space 256 that can store and hold caulking portions 54 that respectively crimp the cable ends 53 that are the ends of the pair of cables 51. The cable fixing portion 255 communicates with the end holding space 256 and passes the cable 51. It has a cable groove 257 that can be used. The cable groove 257 is formed over the entire arc surface on the outer peripheral side of the pair of arm members 252. Due to such a structure, the pair of cables 51 protruding from the outer cable 52 enters the cable groove 257 and is guided to the end holding space 256, and the caulking portion 54 for caulking the cable end 53 is placed inside the end holding space 256. It is retained by being stored and held.

  Further, as shown in FIGS. 6A, 6B, and 7, the base 151 has a positioning hole 154 formed on the lower surface thereof. The arrangement position is a position immediately below the cable holding hole 152. The positioning hole 154 is used for positioning when the remote operation device 21 is attached to a remote operation device mounting portion 351 (see FIG. 9) described later.

  FIG. 9 is a front view showing a remote operation device mounting portion 351 disposed in the vicinity of a damper which is an operated portion. The remote operation device mounting portion 351 is provided with a positioning pin 353, an operation portion 354, and a pair of fixed claw portions 355 on a flat substrate 352.

  FIG. 10 is a vertical side view of the remote operation device 21 attached to the remote operation device mounting portion 351. FIG. 11 is a front view of the remote operation device 21 attached to the remote operation device mounting portion 351. Positioning pins 353 provided on the substrate 352 are fitted into positioning holes 154 formed on the lower surface of the base 151 of the remote control device 21 to position the base 151.

  The operation unit 354 has an operation shaft 356 that is rotatably attached to the substrate 352. The operating shaft 356 is connected to a rotating shaft of a damper (not shown) provided in the air conditioning duct. Therefore, if the operating shaft 356 rotates, the damper also rotates. Such an operating part 354 has an operating lever 357 formed integrally with the operating shaft 356. The actuating lever 357 is formed in a shape and size that extend to the positions of both ends of the pair of arm members 252 in an expanded state, and a convex portion 358 that restricts the operation of the arm members 252 to further expand. (See FIG. 11).

  Furthermore, the operating part 354 has a connecting pin 359 that fits in the connecting hole AD106 formed in the connecting body AD103 of the adapter AD101, coaxially with the operating shaft 356. The connecting pin 359 is formed according to the shape and size of the connecting hole AD106, and has a flat portion 359a similar to the flat portion AD106a of the connecting hole AD106. Accordingly, the connection hole AD106 of the adapter AD101 and the connection pin 359 of the operating portion 354 are coupled to each other, and when the adapter AD101 of the rotating body 251 rotates, the operating portion 354 also rotates, and the damper connected to the operating shaft 356 also rotates. To do.

  The fixed claw portion 355 is a pair of members that sandwich and hold both side portions of the base portion 151 of the remote control device 21 that is positioned by the positioning pin 353 and attached to the operating portion 354. Such a fixed claw portion 355 is formed by providing a claw portion 361 at the distal end portion of a pair of elastic pieces 360 that are vertically arranged and face each other from the substrate 352. The facing distance between the pair of elastic pieces 360 is formed to be substantially the same width as the width of the base portion 151, and the facing distance between the pair of claw portions 361 is formed to be narrower than the width of the base portion 151.

  In such a configuration, the remote operation device 21 can be detachably attached to the remote operation device mounting portion 351 using the positioning pin 353, the operation portion 354, and the fixed claw portion 355. That is, the remote operation device 21 is attached to the remote operation device mounting portion 351 by causing the positioning pin 353 to position the base 151 and causing the operation portion 354 to hold the adapter AD101 of the rotating body 251. At this time, the base 151 is positioned by fitting a positioning pin 353 into the positioning hole 154. Further, the adapter AD101 of the rotating body 251 is attached to the operating portion 354 by fitting the connecting pin 359 of the operating portion 354 into the connecting hole AD106. In this state, the pair of fixed claws 355 provided in the remote operation device mounting portion 351 holds the base 151 of the remote operation device 21 with the pair of claws 361. The rotating body 251 is integrated with the operating lever 357 by restricting the position of the pair of arm members 252 to be expanded to a pair of convex portions 358 formed on the operating lever 357. Thus, the remote operation device 21 is attached to the remote operation device mounting portion 351.

  Here, when the remote operation device 21 is attached to the remote operation device mounting portion 351, the base portion 105 is connected to the connection pin AD359 with the connection hole AD106 of the adapter AD101 fitted to the connection pin 359 of the remote operation device mounting portion 351. When moved in a direction away from 359, the rotating body 251 moves to the end portion side of the base portion 151 on the opposite side to the drawing direction of the cable 51. That is, the connecting body AD103 of the adapter AD101 is slid by the holding groove 153 of the base 151. Then, under the premise that the cable 51 is stationary, a pair of arm members 252 that initially maintain a narrowed state (stored state) as shown in FIG. Expand as shown in (use condition). This is because the distal ends of the pair of arm members 252 are pulled by the pair of cables 51 as the connecting portion 253 of the rotating body 251 moves. Therefore, the distal end portions of the pair of arm members 252 can be appropriately expanded by setting the separation distance between the positioning pin 353 and the operating portion 354 in the remote operation device mounting portion 351 (FIG. 6 ( b) and FIG. 11). At this time, in the remote operation device mounting portion 351, the pair of spread arm members 252 is controlled by the convex portions 358 formed at both ends of the operating lever 357 of the remote operation device mounting portion 351. The dimensions are defined. In this state, when the positioning hole 154 of the base portion 151 is fitted to the positioning pin 353 of the remote operation device mounting portion 351 and the base portion 151 is pushed toward the substrate 352 of the remote operation device mounting portion 351, the fixed claw portion The base portion 151 is fixed to the remote operation device mounting portion 351 by engaging the claw portion 361 of 355 with the edges on both sides of the base portion 151. As described above, when the remote operation device 21 is attached to the remote operation device mounting portion 351, the connection hole AD106 of the rotating body 251 is fitted to the connection pin 359 of the remote operation device mounting portion 351, and the base portion 105 is connected to the connection pin. The rotator 251 is automatically displaced from the housed state to the used state simply by moving in a direction away from 359. Therefore, the remote operation device 21 can be easily attached to the remote operation device mounting portion 351.

  12A is a front view of the entire apparatus showing a state in which the rotating body 251 is rotated clockwise, and FIG. 12B is a state in which the rotating body 251 is rotated counterclockwise. The remote operation device 21 attached to the remote operation device mounting portion 351 can rotate the rotating body 251 by moving the pair of cables 51 in opposite directions. This will be described with reference to an example shown in FIGS.

  As shown in FIG. 12 (a), when the cable 51 located on the lower side of the drawing is drawn into the outer cable 52, the arm member 252 located on the lower side of the drawing of the rotating body 251 rotates in the clockwise direction. The convex portion 358 is pushed by the arm member 252 and rotates the operating lever 357 in the clockwise direction. As a result, the damper (not shown) provided in the air conditioning duct connected to the operating shaft 356 of the operating unit 354 can be rotated clockwise to adjust the angle. At this time, the arm member 252 located on the upper side of the paper also rotates in the clockwise direction, so that the other cable 51 connected to the tip of the arm member 252 is pulled out from the outer cable 52.

  As shown in FIG. 12B, when the cable 51 located on the upper side of the paper is pulled into the outer cable 52, the arm member 252 located on the upper side of the rotary body 251 rotates in the counterclockwise direction, and the position is regulated. The protruding portion 358 is pushed by the arm member 252 and rotates the operating lever 357 in the counterclockwise direction. As a result, the damper (not shown) provided in the air conditioning duct connected to the operating shaft 356 of the operating portion 354 can be rotated counterclockwise to adjust its angle. At this time, the arm member 252 located on the lower side of the paper also rotates counterclockwise, so that the other cable 51 connected to the tip of the arm member 252 is pulled out from the outer cable 52.

  Therefore, the same remote operation device 21 as the remote operation device 21 is connected to the end opposite to the cable end 53 which is one end side of the pair of cables 51 connected and fixed to the rotating body 251, and this remote operation device. By connecting 21 to a drive unit (not shown), the rotational motion of the drive unit can be converted into the rotational motion of the damper, which is the driven unit, and transmitted. The remote control device 21 connected to the end of the pair of cables 51 opposite to the cable end 53 is not shown, but for convenience, the base 151 included in the remote control device 21 is a second base, The rotating body 251 is referred to as a second rotating body. In implementation, the second rotating body is connected to the rotating shaft (all not shown) of the operation knob provided on the air conditioning control panel of the automobile. Accordingly, when the operation knob is rotated, the second rotating body is also rotated, whereby the pair of cables 51 are moved in opposite directions within the outer cable 52. Then, as shown in FIGS. 12 (a) and 12 (b), in the remote control device 21 connected to the damper (not shown) as the driven portion, one cable 51 is pulled into the outer cable 52, By pulling the other cable 51 out of the outer cable 52, the rotating body 251 alternatively rotates clockwise and counterclockwise. When the rotating body 251 rotates, the operating portion 354 also rotates, and the damper also rotates through the operating shaft 356. Thus, by rotating the operation knob provided in the air conditioning control panel of the automobile, the damper provided in the air conditioning duct can be rotated and adjusted.

  Here, an operation procedure for connecting the remote control device 21 to a damper (all not shown) as a driven part provided in the air conditioning duct will be described. First, a remote control device 21 connected to a damper is inserted into an opening (not shown) for mounting an air conditioning control panel of an automobile. At this time, the pair of rotators 251 are kept in a storage state as shown in FIG. Next, in order to guide the remote control device 21 inserted into the opening to the position of a damper provided in the air conditioning duct, the remote control device 21 is passed through spaces between various structures. In this case, since the space between the various structures through which the remote control device 21 passes is generally narrow, the remote control device 21 must be passed through the narrow space. On the other hand, the remote control device 21 in which the pair of rotating bodies 251 are in the housed state is easy to pass through even in a narrow space because the base 151 and the pair of rotating bodies 251 overlap and take an elongated shape. Therefore, the workability can be improved. Moreover, the rotating body 251 in the housed state maintains the state of being held by the base 151 by the rotating body holding mechanism RH ′. Therefore, unless the rotating body 251 is moved to the end portion side of the base portion 151 on the side opposite to the drawing direction of the cable 51, the pair of arm members 252 are not in the expanded state as shown in FIG. 6B or FIG. Accordingly, it is possible to prevent the occurrence of an accident that the pair of rotating bodies 251 unexpectedly expands and gets caught on some structure during the transportation of the remote operation device 21.

  If the remote operation device 21 is carried to the installation position of the remote operation device mounting portion 351 located in the vicinity of the damper, the remote operation device 21 is attached to the remote operation device mounting portion 351. Then, the pair of arm members 252 are opened and put into use.
