[0012] The front working mechanism 4 also has a boom cylinder 19 that drives the boom 12, an arm cylinder 20 that drives the arm 13, and a working tool cylinder 21 that drives the working tool 14. The boom cylinder 19, the arm cylinder 20, and the working tool cylinder 21 are each formed of a hydraulic cylinder. As shown in Figures 1 and 2, the work machine 1 has a driver's section 41 equipped with a driver's seat 6 where an operator (driver) sits. The driver's section 41 is mounted on the machine body 2. The driver's section 41 has a floor section 42 attached to the machine body 2.
[0013] 2, a cover body 16 that houses devices (e.g., hydraulic oil tank, control valve, battery, etc.) mounted on the machine body 2 is provided on the right side of the machine body 2 and to the side of the driving section 41 in the machine body width direction K2. A bonnet 17 that houses a prime mover (engine) is provided behind the driving section 41. As shown in Figures 2 and 3, the driver's section 41 has a seat base 43 to which the driver's seat 6 is attached. The seat base 43 is attached to the floor section 42 and the machine body 2. Therefore, the driver's section 41 (driver's seat 6) is mounted on the machine body 2. As shown in Figure 2, the driver's seat 6 has a seat section 6A for the operator to sit on (supporting the operator's buttocks) and a backrest section 6B that supports the operator's back. The front is the front side of the operator seated in the driver's seat 6.
[0014] 2, the driver's section 41 has a console (operation console) 44L arranged on one side of the driver's seat 6 in the vehicle width direction K2, and a console (operation console) 44R arranged on the other side of the driver's seat 6 in the vehicle width direction K2. Specifically, the console 44L is arranged on the left side of the driver's seat 6, and the console 44R is arranged on the right side of the driver's seat 6.

[0015] The left operating device 45L and the right operating device 45R can operate two operating objects. For example, the operating device 45L can operate the rotation of the machine body 2 and the swinging of the arm 13. The operating device 45R can operate the swinging of the boom 12 and the swinging of the work tool 14. As shown in Fig. 1, the driver's section 41 has two travel levers 48L, 48R arranged in front of the driver's seat 6. The two travel levers 48L, 48R are arranged side by side in the machine body width direction K2. The left travel lever 48L can operate the first crawler travel body 3A, and the right travel lever 48R can operate the second crawler travel body 3B.
[0016] As shown in Fig. 2, a pedal member 50A is provided on the left side of the machine body 2 in front of the driver's seat 6, and a pedal member 50B is provided on the right side. The pedal member 50A and the pedal member 50B are members that are stepped on and operated by an operator seated in the driver's seat 6, and the pedal member 50A is, for example, a spare pedal. The spare pedal is an operating member that operates a hydraulic attachment having a hydraulic actuator when the hydraulic attachment is attached as the working tool 14. The pedal member 50B is a swing pedal. The swing pedal is an operating member that operates a hydraulic cylinder that swings the swing bracket 10.
[0017] As shown in Figs. 3 and 4, a meter 51 is provided at the front of the console 44R. The meter 51 is provided so as to extend in an inclined direction that transitions upward as it approaches the front. The meter 51 has a meter cover 51A and a display unit (including a liquid crystal screen, etc.) 51B provided on the rear side of the meter cover 51A. The display unit 51B is provided so as to face the operator seated in the driver's seat 6. For example, basic information about the work machine 1, an image of the surroundings of the work machine 1, information necessary for performing various settings of the work machine 1, etc. can be displayed on the display unit 51B.
[0018] 4, the console 44R has a console frame 53 that supports various switches, an operating device 45R, a dozer lever 47, a console cover 54, and a meter 51 that are provided on the console 44R. The console frame 53 is attached to the seat base 43. Therefore, the console frame 53 (console 44R) is fixed to the machine body 2 via the seat base 43 and the floor 42. The console frame 53 has a rear frame 55 that constitutes the rear side, and a front frame 56 that constitutes the front side.
[0019] 5 and 6, the front frame 56 has a main frame 56A and a meter frame 56B attached to the front of the main frame 56A. The meter cover 51A and the display unit 51B are attached to the meter frame 56B. As shown in Fig. 3, the work machine 1 is equipped with a communication unit 58. As shown in Figs. 1 and 2, the communication unit 58 is installed near the outer edge of the driving section 41. In this embodiment, the communication unit 58 is provided on the right side and front of the machine body 2 (driving section 41).
[0020] As shown in Figs. 4 and 6, the communication unit 58 is disposed on the side of the console 44R (console frame 53) in the vehicle width direction K2. More specifically, the communication unit 58 is disposed on the side of the console 44R opposite the driver's seat 6 (on the right in this embodiment). By disposing the communication unit 58 (DCU 60 and IPU 59) on the side of the console 44R opposite the driver's seat 6, it is possible to prevent the communication unit 58 from obstructing the operator's view. The communication unit 58 includes an IPU (Information processing unit) 59 and a DCU (Direct Communication Unit) 60.
[0021] The IPU 59 is an "information processing device" that temporarily stores information about the working machine 1 and performs a predetermined process (for example, compression process, etc.). As shown in FIG. 7, the IPU 59 is connected to a communication port of an in-vehicle communication network and a communication port of an in-vehicle fault diagnosis device (OBD: On-Board Diagnostics) via a harness 64, not shown. In detail, the IPU 59 is connected to a communication port of the in-vehicle communication network via the harness 64 and a connector 62A. The in-vehicle communication network is composed of a CAN (Controller Area Network) or FlexRay, etc., mounted on the working machine 1. The IPU 59 is also connected to a communication port of the in-vehicle fault diagnosis device via the harness 64 and a connector 62B. The IPU 59 transmits and receives information about the working machine 1 from the communication network and the in-vehicle fault diagnosis device. The harness 64 is composed of a plurality (a large number) of electric wires (wiring) bundled together. Further, the harness 64 branches into a branch portion 64a connected to the DCU 60 via a connector 84A, a branch portion 64b connected to the IPU 59 via a connector 84B, and a branch portion 64c connected to a fuse 68 for the DCU 60, near the communication unit 58 (IPU 59). The IPU 59 is connected to the DCU 60 via the harness 64 and transmits data to the DCU 60. Further, the IPU 59 and the DCU 60 are connected to a power supply port (not shown) via the harness 64 and a connector 63A, and are supplied with power from the power supply port.
[0022] In a working machine 1 that is not equipped with a cabin, the in-vehicle communication network and the communication port of the in-vehicle fault diagnosis device are disposed inside the seat base 43 of the driving section 41. In a working machine 1 that is equipped with a cabin, they are provided in a different location of the driving section 41. The length of the harness 64 from the communication unit 58 to the connectors 62A, 62B is formed to a length that allows connection to the in-vehicle communication network and the communication port of the in-vehicle fault diagnosis device, regardless of whether the communication unit 58 is mounted on a working machine 1 that is not equipped with a cabin or a working machine 1 that is equipped with a cabin. In addition, when the communication unit 58 is mounted on a working machine 1 that is equipped with a cabin, the working machine 1 has a harness 64d and a connector 63B that connect the IPU 59 to a connection port of the harness of the cabin (not shown).
[0023] In this embodiment, the harness 64 is a common harness 64 for a case where the communication unit 58 is mounted on a work machine 1 equipped with a cabin and a case where the communication unit 58 is mounted on a work machine 1 not equipped with a cabin. In other words, the harness 64 can be used in common for a work machine 1 equipped with a cabin on the machine body 2 and a work machine 1 not equipped with a cabin on the machine body 2.
[0024] The DCU 60 is a "communication device" that communicates data with external devices (not shown). The DCU 60 receives and transmits data from the IPU 59. The DCU 60 also transmits the data received from the IPU 59 and data such as location information to a server. The server is, for example, a server installed at a manufacturer (manufacturing company) that manufactures the work machine 1, or a server installed at a dealer (sales and maintenance company) that sells and maintains the work machine 1.
[0025] As shown in Fig. 5, the IPU 59 has a generally rectangular parallelepiped shape with a surface facing the vehicle width direction K2 being generally rectangular, and is disposed sideways with the longitudinal direction of the parallelepiped coinciding with the front-rear direction K1. As shown in Fig. 14, the IPU 59 has a generally rectangular parallelepiped shape with a width (width in the thickness direction) of the vehicle width direction K2 narrower than its width in the up-down direction and its width in the front-rear direction K1. The IPU 59 has a connection portion 59a on its underside to which the harness 64 is connected.
[0026] As shown in Fig. 5, the DCU 60 has a generally rectangular parallelepiped shape with a device front surface 60A being generally rectangular, and is disposed vertically with the longitudinal direction of the parallelepiped coinciding with the up-down direction. Also, as shown in Fig. 14, the DCU 60 has a generally rectangular parallelepiped shape with a width in the machine width direction K2 (width in the thickness direction) narrower than the width in the up-down direction and the width in the front-rear direction K1. As shown in Figs. 3 to 5, the DCU 60 and the IPU 59 are arranged side by side in the front-rear direction K1. By arranging the DCU 60 and the IPU 59 side by side in the front-rear direction K1, the DCU 60 and the IPU 59 can be arranged compactly in a narrow space on the side opposite the driver's seat 6 of the console 44R. In particular, as shown in Fig. 16, in a work machine 1 equipped with a cabin 15, the left side panel 15A of the cabin 15 is arranged on the side opposite the driver's seat 6 of the front frame 56 (console 44R), so that the space on the side opposite the driver's seat 6 of the console 44R is narrow. However, by arranging the DCU 60 and the IPU 59 side by side in the front-rear direction K1, the DCU 60 and the IPU 59 can be arranged compactly in a narrow space.
[0027] In this embodiment, the DCU 60 is disposed in front of and spaced from the IPU 59. Alternatively, the IPU 59 may be disposed in front and the DCU 60 may be disposed in the rear. 2, the DCU 60 is disposed so that the equipment front surface 60A of the DCU 60 faces the side (left) of the driver's seat 6 and is spaced upward from the floor portion 42 of the driver's section 41. In other words, the DCU 60 is disposed so that the equipment front surface 60A of the DCU 60 faces the space on the floor portion 42 in front of the driver's seat 6. In addition, a pedal member 50B is disposed on the side of the DCU 60 on the driver's seat 6 side. By disposing the IPU 59 behind the DCU 60 (not disposing the IPU 59 and the DCU 60 side by side in the vehicle width direction K2), the DCU 60 can be spaced apart from the pedal member 50B in the vehicle width direction K2, and the operator's foot can be prevented from contacting the DCU 60.
[0028] 8 shows the DCU 60 as viewed from the device rear side of the DCU 60 (the side opposite to the device front side 60A). The DCU 60 has a case 72 and a cover 73 that covers the case 72 from the device front side 60A. The DCU 60 has a connection part 60a to which a harness 64 is connected. The connection part 60a is provided on the lower rear side of the case 72. As shown in FIG. 8, the DCU 60 has an electronic board 91 housed in the case 72. The case 72 is formed in a substantially rectangular parallelepiped shape, and a communication antenna (e.g., a 3G antenna, etc.) 92 and a positioning antenna (GPS antenna) 93 are attached to the front side of the electronic board 91, where electronic components are attached. The electronic board 91 is housed in the case 72 so that the front side faces the device front surface 60A. The communication antenna 92 is an antenna for communicating with a server, and is provided on the upper and lower parts of the electronic board 91. The communication antenna 92 is built in the DCU 60. In the DCU 60 of this embodiment, since the communication antenna 92 is built in the DCU 60, a communication-enabled state can be maintained when a fraudulent act such as theft (such as removing the DCU 60) is occurring, and a report can be sent to a predetermined report destination.
[0029] The positioning antenna 93 receives satellite signals transmitted from positioning satellites. The positioning antenna 93 is provided on the lower right side of the electronic board 91. The work machine 1 detects its own position (positioning information including latitude and longitude) by a positioning system based on the satellite signals received by the positioning antenna 93. In detail, the work machine 1 obtains the position and direction of the work machine 1 by using a well-known Global Positioning System (GPS), which is an example of a Global Navigation Satellite System (GNSS), (for example, by RTK-GPS suitable for positioning of moving objects). That is, the work machine 1 communicates with a base station (reference station) installed at a known position, and the base station transmits positioning data (correction information) obtained by receiving radio waves from the positioning satellite to the work machine 1. The work machine 1 detects its own position (latitude and longitude) based on the positioning data obtained by receiving radio waves from the positioning satellite and the positioning data from the base station. The DCU 60 transmits and receives position information.
[0030] As shown in Fig. 3, the DCU 60 is disposed at a position exposed forward from the console 44R (meter 51) in a side view. Also, as shown in Fig. 2, the device front surface 60A faces the opposite side to the cover body 16 in the machine width direction K2. This ensures communication of the DCU 60. As shown in Fig. 4, the work machine 1 has a support bracket 22 that supports the console 44R. The support bracket 22 is disposed in the front of the console 44R and supports the front of the console 44R (front frame 56). More specifically, the support bracket 22 is disposed on the right side of the front of the console 44R (the side opposite the driver's seat 6 of the console 44R) and supports the front of the console 44R (front frame 56). As shown in Figs. 3 and 5, the support bracket 22 is erected on the machine body 2 side below the front frame 56. As shown in Figs. 5 and 6, the support bracket 22 is disposed toward the right of the front frame 56.
[0031] 9 and 10, the support bracket 22 has a support member 23 extending in the vertical direction, and a bracket plate (bracket member) 24 fixed to the upper part of the support member 23. The support member 23 is formed of a strip material with the vertical direction as the longitudinal direction. The support member 23 has, at its lower part, a base portion 23a extending rightward from the lower end of the support member 23.
[0032] As shown in Fig. 9, the base portion 23a (the lower portion of the support member 23) is fixed to an attachment portion 26a provided on the fixing member 26 via a bolt member 18 or the like. That is, the support member 23 is provided upright on the attachment portion 26a (fixing member 26). Furthermore, as shown in Fig. 3, the fixing member 26 is attached to the machine body 2. Therefore, the support bracket 22 is provided upright on the machine body 2 side via the fixing member 26.
[0033] As shown in Fig. 12, the fixing member 26 is disposed at the lower part of the surface (left surface) 16a on the inner side in the machine body width direction K2 of the cover body 16. As shown in Fig. 13, a notched opening 27 is formed at the lower part of the left surface 16a of the cover body 16. This notched opening 27 is for preventing interference with, for example, a hydraulic hose connected to a control valve housed in the cover body 16. As shown in Fig. 12, the fixing member 26 is a cover member provided so as to cover (block) the notched opening 27 of the cover body 16.
[0034] As shown in Fig. 3, the fixing member 26 is attached to a rotating frame 28 that forms the framework of the machine body 2. The rotating frame 28 has a rotating base plate 29 that forms the bottom of the machine body 2, a vertical rib 30 fixed onto the rotating base plate 29, a support bracket 11 fixed to the front of the vertical rib 30, and the like. The fixing member 26 is fixed to a plate member 32 fixed to the upper part of a support pillar 31 erected on the rotating base plate 29, and to the upper support bracket 11 via bolts or the like. In this way, the fixing member 26 is fixed to the machine body 2.
[0035] 10 and 11, the bracket plate 24 is formed of a plate material and is disposed on the upper left side of the strut member 23 so that the plate surface faces the fuselage width direction K2. The bracket plate 24 has an upper first portion 24a, a second portion 24b extending downward from a front portion of the first portion 24a, and a third portion 24c extending forward from the second portion 24b. A pair of front and rear nut members 33 are fixed to the right surface of the first portion 24a.
[0036] 4 and 9, the front frame 56 is provided with a bracket mounting portion 34. More specifically, the bracket mounting portion 34 is provided on the front and lower portion of the front frame 56 (main frame 56A). The first portion 24a is attached to the bracket mounting portion 34 by overlapping the left surface of the first portion 24a with the right surface of the bracket mounting portion 34 and using a bolt member 35 which penetrates the bracket mounting portion 34 and the first portion 24a from the left and is screwed into the nut member 33.
[0037] 11, an upper portion of the support member 23 is fixed to the second portion 24b. More specifically, the upper portion of the support member 23 is overlapped with the right surface of the second portion 24b and fixed by welding or the like. The third portion 24c protrudes forward from the support member 23. 10 and 11, the support bracket 22 is provided with an attachment bracket 36 formed of a plate material. More specifically, the attachment bracket 36 is provided on the upper part of the support bracket 22. The attachment bracket 36 is a member for attaching a unit bracket 65, which will be described later. In other words, the attachment bracket 36 is provided for attaching the unit bracket 65 to the support bracket 22.
[0038] The mounting bracket 36 is provided so as to protrude from the support bracket 22 to the side (right side) opposite to the driver's seat 6. In the example shown in Figs. 10 and 11, the mounting bracket 36 is fixed to the third portion 24c and provided so as to protrude to the right from the third portion 24c. More specifically, as shown in Fig. 11, the mounting bracket 36 has a fixing portion 37 and a mounting wall 38. The fixing portion 37 has a first wall portion 37a and a second wall portion 37b. The first wall portion 37a is formed so that the plate surface faces the up-down direction and is disposed in front of the upper portion of the support member 23 and to the right of the upper portion of the third portion 24c. The second wall portion 37b extends downward from the rear end of the first wall portion 37a. The first wall portion 37a and the second wall portion 37b are fixed to the right surface of the third portion 24c by welding or the like. The second wall portion 37b may also be welded to the support member 23.
[0039] The mounting wall 38 extends rightward and forward from the right end of the first wall portion 37a of the fixed portion 37. Therefore, the mounting wall 38 is located forward of the support member 23. The plate surface of the mounting wall 38 faces the vertical direction. A pair of front and rear insertion holes 38b are formed in the mounting wall 38 so as to penetrate the mounting wall 38 in the vertical direction. The insertion holes 38b are formed as elongated holes that are long in the machine body width direction K2. The lower surface of the mounting wall 38 is the mounting surface 38a to which the unit bracket 65 is attached. The upper surface of the mounting wall 38 may be the mounting surface to which the unit bracket 65 is attached.
[0040] The shapes of the bracket plate 24 and the mounting bracket 36 are not limited to those shown in Figures 10, 11, etc., and may be modified in various ways. For example, they may be configured as in the embodiment (other embodiment) shown in Figures 17 and 18. In this other embodiment, as shown in Figures 17 and 18, the bracket plate 24 of the support bracket 22 has a first portion 24a and a second portion 24b. It does not have the third portion 24c of the above embodiment. In addition, the support member 23 is exposed forward from a front end 24d of the second portion 24b.
[0041] The fixing portion 37 of the mounting bracket 36 has a first wall portion 37a, a second wall portion 37b, and a third wall portion 37c. The first wall portion 37a is formed so that the plate surface faces the up-down direction and is disposed in front and to the right of the upper portion of the support member 23. The second wall portion 37b extends downward from the rear end of the first wall portion 37a. The third wall portion 37c extends downward from the left end of the first wall portion 37a. The third wall portion 37c also has an extension portion 37d that extends rearward and is located to the right of the support member 23. The extension portion 37d abuts against the right surface of the support member 23 and is fixed to the right surface by welding or the like. The second wall portion 37b is fixed to the extension portion 37d by welding or the like.
[0042] In the other embodiment described above, the fixing portion 37 of the mounting bracket 36 is fixed to the support member 23, but this is not limited thereto, and the fixing portion 37 may be formed so as to be fixed across the bracket plate 24 and the support member 23 (to both the bracket plate 24 and the support member 23). In other words, it is sufficient that the fixing portion 37 of the mounting bracket 36 is fixed to the upper portion of the support bracket 22.
[0043] 5 and 9, a cover member 39 is disposed on the side of the support bracket 22 on the driver's seat 6 side. As shown in Fig. 5, the cover member 39 extends from the rear end of the DCU 60 to the rear of the IPU 59, and covers the branched portions 64a, 64b, and 64c of the harness 64 from the driver's seat 6 side. For example, it is conceivable that a part (such as the claw of the bucket 14) may be placed on the floor section 42 to the left of the support bracket 22 (to the side of the driver's seat 6), but if a part is placed on the floor section 42 to the left of the support bracket 22, there is a concern that the part may come into contact with the harness 64 due to vibrations or the like of the machine body 2. In such a case, the harness 64 can be protected by the cover member 39.
[0044] 9, the cover member 39 has a midpoint (approximate center) in the front-rear direction K1 attached to the support member 23 from the inner side (left side) in the width direction K2 of the aircraft body by a bolt 61 or the like. A stay member 40 is fixed to the rear upper surface of the cover member 39. The stay member 40 is fixed from the left side by a bolt 52 to an attachment portion 49 provided on the lower part of the front frame 56. 14 and 15, the work machine 1 has a unit bracket 65 to which the communication unit 58 is attached. As shown in Fig. 6, the unit bracket 65 is disposed on the side (right side) opposite the driver's seat 6 of the front frame 56 (console 44R) along the front-rear direction K1.
[0045] As shown in FIGS. 14 and 15, the unit bracket 65 has a mounting member 66, a vertical member 67, a first bracket member 69, a second bracket member 70, and a mounting stay 71. As shown in FIG. 11, the mounting member 66 is formed of a plate material, arranged so that the plate surface faces the up-down direction, and overlaps with the lower surface (mounting surface 38a) of the mounting wall 38 of the mounting bracket 36. As shown in FIG. 14, a pair of front and rear nut members 75 are fixed to the lower surface of the mounting member 66. The mounting member 66 is attached to the mounting wall 38 (mounting bracket 36) from above by the bolt members 74 that penetrate the insertion holes 38b of the mounting wall 38 and the mounting member 66 and are screwed into the nut members 75 (see FIGS. 4, 6, and 9). In this way, the mounting member 66 of the unit bracket 65 can be attached to the mounting wall 38 of the mounting bracket 36 from above, so that the workability of mounting the unit bracket 65 is good. In addition, since the insertion holes 38b are elongated holes in the machine body width direction K2, the mounting position of the unit bracket 65 can also be adjusted in the machine body width direction K2.
[0046] As shown in Figures 10 and 14, the vertical member 67 is disposed below the mounting member 66 so as to extend in the vertical direction. More specifically, the vertical member 67 is formed of a channel steel, and disposed so that the opening side faces leftward and the longitudinal direction coincides with the vertical direction. The mounting member 66 is fixed to the upper part of the vertical member 67 by welding or the like. As shown in Figure 14, a reinforcing member 85 is fixed across the vertical member 67 and the mounting member 66 by welding or the like. As shown in Figure 4, the vertical member 67 is located forward of the support member 23.
[0047] 14 and 15 , the first bracket member 69 is fixed to the front of the vertical member 67, and the second bracket member 70 is fixed to the rear of the vertical member 67. One of the IPU 59 and the DCU 60 is attached to the first bracket member 69, and the other of the IPU 59 and the DCU 60 is attached to the second bracket member 70. In this embodiment, since the DCU 60 is disposed in front of the IPU 59, the first bracket member 69 is formed in a structure that allows the DCU 60 to be attached, and the DCU 60 is attached to the first bracket member 69. In addition, the second bracket member 70 is formed in a structure that allows the IPU 59 to be attached, and the IPU 59 is attached to the second bracket member 70.
[0048] Next, the structures of the first bracket member 69 and the second bracket member 70 in this embodiment will be described in detail. 14 and 15, the first bracket member 69 has a bracket main body 76 and a main body support bracket 77. The bracket main body 76 is a plate member formed from a metal plate material. The bracket main body 76 is disposed in front of the vertical member 67 with a gap therebetween so that the plate surface faces the fuselage width direction K2.
[0049] The main body support bracket 77 supports the bracket main body 76 with respect to the vertical member 67. The main body support bracket 77 has a support main body 77A and a reinforcing plate 77B. The support main body 77A is formed of a channel steel and is disposed from the upper part of the vertical member 67 to the right surface of the bracket main body 76 so that the opening side faces leftward and extends in the front-rear direction K1. The rear part of the support main body 77A abuts against the front surface of the upper part of the vertical member 67 and is fixed to the front surface by welding or the like. Therefore, the support main body 77A protrudes forward from the upper part of the vertical member 67. The front part of the support main body 77A is fixed to the middle part in the up-down direction of the right surface of the bracket main body 76 by welding or the like. The reinforcing plate 77B is provided across the right surface of the vertical member 67 and the right surface of the support main body 77A, and is fixed to the vertical member 67 and the support main body 77A by welding or the like.
[0050] The rear side of the DCU 60 is attached to the left side of the bracket body 76. In more detail, as shown in Fig. 14, the bracket body 76 has a plurality of cover attachment parts 76a, and attachment pieces 73a at the four corners of the cover 73 are attached to these cover attachment parts 76a with screws 78 or the like. The case 72 is also attached to the bracket body 76 with screws 79 (see Fig. 15) or the like.
[0051] 10, 14, and 15, bracket body 76 has a cutout portion 95 formed by cutting out a portion corresponding to communication antenna 92. Communication antenna 92 has directivity in the thickness direction of electronic board 91. Cover 73 is made of resin, and by cutting out the portion of bracket body 76 corresponding to communication antenna 92, the radio wave directivity of communication antenna 92 is not hindered.
[0052] As shown in Fig. 14, the work machine 1 has a cover 81 that covers the right surface of the bracket body 76 (the side opposite to the side where the DCU 60 is attached). The cover 81 is made of resin and is formed into a shape that covers the bracket body 76, the front part of the support body 77A, and the peripheral edge of the DCU 60 (cover 73) from the right side. The cover 81 improves the appearance.
[0053] The cover 81 is attached to the support body 77A by screws 80 (see FIG. 15). The cover 81 is made of resin, so that it does not interfere with the radio wave directivity of the communication antenna 92. When the communication unit 58 is installed on a cabin-type work machine 1, as shown in FIG. 16, the left side panel 15A of the cabin 15 is positioned on the side of the console 44R opposite the driver's seat 6 in the machine width direction K2, so that the above-mentioned cover 81 covering the right surface of the bracket main body 76 can be omitted.
[0054] As shown in Figs. 14 and 15, the second bracket member 70 is formed of a plate material and is disposed behind the vertical member 67 so that the plate surface faces the fuselage width direction K2. The front end of the second bracket member 70 abuts against the rear surface of the vertical member 67 and is fixed to the rear surface by welding or the like. A notch 82 is formed in the lower part of the second bracket member 70. The notch 82 is formed from the middle part of the second bracket member 70 in the front-rear direction K1 to the rear end, and is open downward and rearward. As shown in Fig. 5, the second bracket member 70 has equipment mounting parts 70a at the lower front part and the upper rear part. A nut member 83 is fixed to the right surface of each equipment mounting part 70a. The IPU 59 is provided with mounting bosses 59b at the lower front part and the upper rear part. The IPU 59 is positioned on the left surface of the second bracket member 70 and is fixed to the second bracket member 70 by a bolt (not shown) that passes through the mounting boss 59b and the equipment mounting portion 70a of the second bracket member 70 and is screwed into the nut member 83.
[0055] As described above, by arranging the first bracket member 69 to extend forward in a plan view from the vertical member 67 extending in the vertical direction, and arranging the second bracket member 70 to extend rearward from the vertical member 67 in a plan view, the unit bracket 65 can be compactly arranged on the side (right side) of the console 44R opposite the driver's seat 6. In addition, by arranging the bracket main body 76 to which the DCU 60 is attached and the second bracket member 70 to which the IPU 59 is attached side by side in the fore-and-aft direction K1 so that the plate thickness direction coincides with the aircraft width direction K2, and attaching the DCU 60 to the bracket main body 76 so that the thickness direction coincides with the aircraft width direction K2, and attaching the IPU 59 to the second bracket member 70 so that the thickness direction coincides with the aircraft width direction K2, the communication unit 58 and the unit bracket 65 can be compactly arranged on the side of the console 44R opposite the driver's seat 6.
[0056] As shown in Figures 14 and 15, the mounting stay 71 is formed of a plate material and has an upper wall 71a fixed to the lower end of the vertical member 67 by welding or the like, a side wall 71b extending downward from the right end of the upper wall 71a, and a reinforcing plate 71c fixed across the upper wall 71a and the side wall 71b. 10, the side wall 71b of the mounting stay 71 is fixed to the side wall portion 26b of the fixing member 26 by bolts 86 or the like. This stably supports the lower part of the vertical member 67 (supports the unit bracket 65) and also stably supports the upper part of the mounting bracket 36. In addition, the mounting stay 71 is fixed to the lower end of the vertical member 67 located forward of the support member 23 and is positioned offset forward of the support member 23, so that when the mounting stay 71 is fixed to the fixing member 26 by bolts, the support member 23 does not get in the way of the mounting stay 71 being attached.
[0057] As shown in Figures 14 and 15, the mounting member 66 is provided with a fuse stay 87 to which a fuse 68 (see Figure 7) for the DCU 60 is attached. The fuse stay 87 has a lower portion fixed to the lower front surface of the mounting member 66, and is formed in an inclined shape that moves leftward as it extends upward, such that the upper portion is shifted leftward from the lower portion. The fuse 68 is attached to the upper portion of the fuse stay 87. By shifting the upper portion of the fuse stay 87 leftward from the lower portion, the fuse 68 can be moved away from the cover 81 to the left, making it easy to attach and detach the fuse 68.
[0058] As shown in FIG. 15, a clamp stay 90 for attaching a clamp 88 (see FIG. 7) that holds the harness 64 is fixed to the rear portion of the second bracket member 70.
