Therefore, the work machine 1 of this embodiment is a work machine 1 in which the area around the driver's seat 6 is not covered by a wall and is open to the outside.

[0013] In this embodiment, the direction towards the front of the operator seated in the operator's seat 6 of the work machine 1 (direction of arrow A1 in Figure 1) is described as the front (front of the machine), the direction towards the rear of the operator (direction of arrow A2 in Figure 1) is described as the rear (rear of the machine), and the direction of arrow A3 in Figure 1 is described as the front-rear direction (front-rear direction of the machine). Furthermore, the direction towards the left of the operator (front side in Figure 1) is described as the left, and the direction towards the right of the operator (back side in Figure 1) is described as the right.

[0014] Furthermore, the horizontal direction, which is perpendicular to the longitudinal direction A3, will be described as the aircraft width direction. The direction from the center of the aircraft width direction toward the right or left side will be described as the outward direction in the aircraft width direction. In other words, the outward direction in the aircraft width direction is the direction away from the center of the aircraft width direction of the aircraft 2. The direction opposite to the outward direction in the aircraft width direction will be described as the inward direction in the aircraft width direction. In other words, the inward direction in the aircraft width direction is the direction approaching the center of the aircraft width direction of the aircraft 2.

[0015] As shown in Figure 1, the travel device 3 is a crawler-type travel device that supports the machine body 2 so that it can move, and includes a travel frame 3A, a first travel device 3L provided on the left side of the travel frame 3A, and a second travel device 3R provided on the right side of the travel frame 3A. The first travel device 3L and the second travel device 3R are driven by a travel motor M1, which is composed of a hydraulic motor (hydraulic actuator).

The left control lever 23L is located in front of and above the left control device 17L and can be tilted forward, backward, left, and right. The remote control valve 24 is a pilot valve operated by the left control lever 23L and is located below the left control lever 23L. The remote control valve 24 is housed inside the console cover 22. The armrest 26L is a component for the operator to rest their elbows on and is located behind the left control lever 23L. The operation lock lever 30 is a lever that switches the hydraulic actuator mounted on the work machine 1 between an operable state and an operable state.

[0022] As shown in Figure 2, the right control device 17R includes a console cover 34, a control lever (right control lever) 23R, a remote control valve (not shown), an armrest 26R, a dozer lever 35, and a number of switches 36.

[0023] The console cover 34 is a cover that covers the frame of the right control unit 17R. The frame of the right control unit 17R is attached to the machine body 2. The right control lever 23R is located in front of and above the right control unit 17R and can be tilted forward, backward, left, and right. The remote control valve is a pilot valve operated by the right control lever 23R, located below the right control lever 23R and covered by the console cover 34. The armrest 26R is a member for the operator to rest their elbows, etc., and is located behind the right control lever 23R. The dozer lever 35 is a lever that operates the dozer device 7. Multiple switches 36 are located on the upper side of the console cover 34 and are switches that operate various devices equipped on the work machine 1.

[0024] As shown in Figure 3, the aircraft body 2 includes a prime mover 91, a radiator 92, an oil cooler 93, and The machine is equipped with components such as a battery 94, a hydraulic pump 95, a fuel tank (tank) 96, a hydraulic oil tank (tank) 97, a control valve 98, and a swing motor 99. The prime mover 91 is, for example, a diesel engine. The prime mover 91 may be a gasoline engine or an electric motor, or it may be a hybrid type having both an engine and an electric motor. A cooling fan 100 is attached to one side (left side) of the prime mover 91 in the width direction of the machine body. The cooling fan 100 is driven by the prime mover 91 and generates cooling air that flows from left to right. In other words, the cooling fan 100 is a suction-type fan that draws in air (outside air) from the left side of the machine body 2 and flows it towards the prime mover 91.

[0025] The radiator 92 is a cooler that cools the coolant that cools the prime mover 91. The oil cooler 93 is a cooler that cools the return hydraulic fluid that comes back from hydraulic actuators such as hydraulic cylinders and hydraulic motors. The battery 94 is a storage battery that supplies power to the electrical components equipped on the work machine 1. The hydraulic pump 95 is driven by the power of the prime mover 91 and discharges hydraulic fluid (pressurized oil) that drives hydraulic actuators such as hydraulic motors and hydraulic cylinders equipped on the work machine 1. The hydraulic pump 95 also discharges pilot pressure to operate hydraulic valves and pressurized oil for signaling. The fuel tank 96 is a tank that stores fuel for the prime mover 91. The hydraulic fluid tank 97 is a tank that stores hydraulic fluid. The control valve 98 controls the flow rate of hydraulic fluid supplied to the hydraulic actuators driven by the hydraulic fluid discharged from the hydraulic pump 95. The slewing motor 99 is a hydraulic motor (hydraulic actuator) that rotates (drives rotations) the machine body 2 around the slewing axis X1.

[0026] As shown in Figure 3, the prime mover 91 is located at the rear of the aircraft body 2, midway along its width. The prime mover 91 is also located below the driver's seat 6. The radiator 92 is located to the left of the prime mover 91 and the cooling fan 100. The oil cooler 93 is located to the left of the radiator 92. The battery 94 is located to the left of the oil cooler 93 and below it. The hydraulic pump 95 is mounted on the other side (right side) of the prime mover 91 in the width direction of the aircraft body. The fuel tank 96 is located on the right side of the aircraft body 2, at the front of the aircraft body 2. In other words, the fuel tank 96 is located to the right and in front of the driver's seat 6. The hydraulic oil tank 97 is located behind the fuel tank 96 and in front of the hydraulic pump 95. In other words, the hydraulic oil tank 97 is located on the right side of the aircraft body 2, midway along its front-to-back direction. The control valve 98 is located at the front of the left side of the aircraft body 2. The slewing motor 99 is located midway along the front-to-rear direction and midway along the width direction of the aircraft body 2. Furthermore, the slewing motor 99 is located in front of the cockpit 6 and below the cockpit 6.

[0027] As shown in Figure 1, a cover device 101 is provided above the aircraft body 2 to cover the onboard equipment such as the prime mover 91 and onboard components such as tanks. As shown in Figure 3, the cover device 101 covers the prime mover 91, radiator 92, oil cooler 93, battery 94, hydraulic pump 95, fuel tank 96, and hydraulic oil tank 97. The control valve 98 and swing motor 99 are located inside the aircraft body 2 (below the floor 21).

[0028] The cover device 101 includes a plurality of cover bodies 101A to 101D. The plurality of cover bodies 101A to 101D includes a cover body (referred to as the first cover body) 101A located below the driver's seat 6. The first cover body 101A is fixedly mounted to the machine body 2. The first cover body 101A also covers the area above and in front of the prime mover 91. The plurality of cover bodies 101A to 101D also includes a cover body (referred to as the second cover body) 101B located behind the first cover body 101A and the prime mover 91. The second cover body 101B covers the area behind the prime mover 91 in an openable and closable manner. The second cover body 101B is supported so as to be openable and closable, with its right end extending vertically on an axis relative to the machine body 2. Furthermore, the multiple cover bodies 101A to 101D have a cover body (referred to as the third cover body) 101C located to the left of the prime mover 91, radiator 92, and oil cooler 93. The third cover body 101C covers the left side of the prime mover 91, etc., in a manner that allows it to be opened and closed. The third cover body 101C is provided with an outside air intake port 89 for taking outside air inward (into the bonnet 14, which will be described later) (see Figure 1). The third cover body 101C is supported so as to be rotatable around an axis that extends vertically at its front end relative to the machine body 2, and is therefore openable and closable. In addition, the multiple cover bodies 101A to 101D have a cover body (referred to as the fourth cover body) 101D located to the right of the machine body 2.

[0029] The rear of the first cover body 101A, the second cover body 101B, the third cover body 101C, and the fourth cover body 101D form an engine room that houses the prime mover 91. In other words, the rear of the first cover body 101A, the second cover body 101B, the third cover body 101C, and the fourth cover body 101D constitute a bonnet 14 that forms the engine room. In addition to the prime mover 91, the engine room houses a radiator 92, an oil cooler 93, a battery 94, and a hydraulic pump 95, etc. The front of the fourth cover body 101D forms a tank room 102 that houses a fuel tank 96 and a hydraulic oil tank 97 (see Figure 8). In other words, the front of the fourth cover body 101D constitutes a tank cover section 103 that forms the tank room 102. In other words, the cover device 101 can be said to consist of a bonnet 14 and a tank cover section 103. The tank cover section 103 (fourth cover body 101D) contains a fuel tank 96 and a hydraulic oil tank 97, but it is sufficient to have at least one tank (for example, a fuel tank 96). The tank room 102 is in communication with the engine room 91A (see Figure 8). The fourth cover body 101D is provided to the right side of the driver's seat 6 and extends forward from the driver's seat 6. That is, the front part of the fourth cover body 101D (tank cover section 103) extends from the side of the driver's seat 6 and forward from the driver's seat 6.

[0030] As shown in Figures 4 to 8, the fourth cover body 101D has a main cover (main wall portion) 104 and a side cover (side wall portion) 105. The main cover 104 and the side cover 105 are formed from metal plate material (sheet metal). The main cover 104 and the side cover 105 may be formed from a plate material such as a resin plate. The main cover 104 has an upper wall 104a, a side wall 104b, and a front wall 104c. The upper wall 104a constitutes the front part of the upper surface of the fourth cover body 101D and forms the upper surface of the tank room 102. The upper wall 104a is slightly inclined downwards towards the front. As shown in Figure 6, the middle and rear portions of the upper surface of the fourth cover body 101D in the front-rear direction are cut out in a notch portion 106 that extends from the middle portion to the rear. The right control device 17R is positioned above this notch portion 106 (see Figure 4).

[0031] As shown in Figures 3 and 4, the side wall 104b forms the right side of the fourth cover body 101D. More specifically, the side wall 104b is provided from the front to the rear of the aircraft body 2 and forms the right side of the tank room 102 and the right side of the engine room 91A. An exhaust port 88 for discharging air taken into the bonnet 14 is formed at the rear of the side wall 104b (see Figures 4 and 6). The upper part of the side wall 104b slopes downward to the right, and the lower part extends vertically (see Figure 7). As shown in Figure 4, the front wall 104c constitutes the front of the fourth cover body 101D. In other words, the front wall 104c forms the front of the tank room 102. The front wall 104c extends downward from the front of the upper wall 104a. The upper part of the front wall 104c slopes downward towards the front, and the lower part extends vertically (see Figure 8).

[0032] As shown in Figures 7 and 8, the lower surface of the tank room 102 is composed of a rotating base plate 5, and the front and right sides of the lower part of the tank room 102 are composed of an aircraft cover 107. The aircraft cover 107 is a cover that forms the outer casing of the front, left side, and right side of the aircraft body 2.

[0033] As shown in Figure 7, the side cover 105 constitutes the upper part of the left side of the tank room 102. In other words, the side cover 105 constitutes the side wall portion on the driver's seat 6 side at the front of the fourth cover body (cover body) 101D. The lower part of the left side of the tank room 102 communicates with the interior of the aircraft body 2.

[0034] As shown in Figure 8, the fuel tank 96 and the hydraulic oil tank 97 have fuel inlets 96A and 97A at their tops. The fuel inlet 96A of the fuel tank 96 is called the fuel inlet, and the fuel inlet 97A of the hydraulic oil tank 97 is called the hydraulic oil inlet. The fuel inlet 96A is composed of a cylindrical portion that extends upward from the main body of the fuel tank 96, communicates with the inside of the fuel tank 96, and has an open top end, and a cap that closes the opening at the top end of the cylindrical portion. Similarly, the hydraulic oil inlet 97A is composed of a cylindrical portion that extends upward from the main body of the hydraulic oil tank 97, communicates with the inside of the hydraulic oil tank 97, and has an open top end, and a cap that closes the opening at the top end of the cylindrical portion.

[0035] As shown in Figure 8, the fuel filler port 96A is located on the upper and rear side of the fuel tank 96. Also, as shown in Figure 7, the fuel filler port 96A is located slightly to the right of the center in the width direction of the aircraft. The hydraulic oil filler port 97A is located on the upper and front side of the hydraulic oil tank 97, as shown in Figure 8. Also, the hydraulic oil filler port 97A is located approximately in the center in the width direction of the aircraft. The fuel filler port 96A is positioned in front of the hydraulic oil filler port 97A.

[0036] As shown in Figure 7, the fuel filler port 96A is tilted in a direction that shifts outward (to the right) in the aircraft width direction as it extends upward. Also, as shown in Figure 8, the fuel filler port 96A is tilted in a direction that shifts forward as it extends upward. In other words, the fuel filler port 96A is tilted in a direction that moves away from the hydraulic fluid filler port 97A as it extends upward. This prevents the hydraulic fluid filler port 97A from getting in the way when refueling.

[0037] As shown in Figures 6, 9, and 10A, the fourth cover body 101D (tank cover portion 103) is provided with an opening 108 formed to expose the fuel filler port 96A and the hydraulic oil filler port 97A. The fuel filler port 96A and the hydraulic oil filler port 97A can be accessed through the opening 108. Specifically, fuel can be supplied from the fuel filler port 96A and hydraulic oil can be supplied from the hydraulic oil filler port 97A through the opening 108. In addition, a device 109 is provided on the upper part of the fuel tank 96, located in front of the fuel filler port 96A. This device is visible through the opening 108. This device 109 is, for example, a fuel expiration sensor that detects when the fuel tank is full. As shown in Figures 6, 7, and 8, the opening 108 is formed in a part of the main cover (main wall portion) 104. More specifically, the opening 108 is formed from the right side of the upper wall 104a of the fourth cover body 101D to the upper part of the side wall 104b and the upper part of the front wall 104c. As shown in Figures 9 and 10A, the opening 108 is formed by the opening periphery portion 110, which is the peripheral edge of the opening 108 in the fourth cover body (cover body) 101D. Note that the location where the opening 108 is formed is not limited to the above-mentioned location, and it is sufficient if it is formed in a part of the main cover (main wall portion) 104. As shown in Figures 10B, 13, and 14, the opening periphery 110 is connected to the main cover (main wall) 104 by a connecting portion 137. In other words, the cover body 101D has a connecting portion 137 that connects the main cover (main wall) 104 and the opening periphery 110.

[0038] As shown in Figure 10B, the connecting portion 137 is formed by bending or curving inward from the main cover (main wall portion) 104, and the contact portion 111, which will be described later, is formed inward from the main cover (main wall portion) 104 at the opening periphery portion 110 or the connecting portion 137.

[0039] As shown in Figures 7 and 8, the fuel filler port 96A protrudes upward from the right edge and front edge of the opening periphery 110. Similarly, the hydraulic fluid filler port 97A also protrudes upward from the right edge and front edge of the opening periphery 110.

[0040] As shown in Figures 4, 5, and 6, the fourth cover body 101D is provided with a fuel filler cover 113 that can open and close the opening 108. As shown in Figures 6 and 11, the fuel filler cover 113 has an upper wall portion 113a, a side wall portion 113b, a front wall portion 113c, and an extended wall portion 113d. As shown in Figures 12 and 13, when the fuel filler cover 113 is closed, the upper wall portion 113a is formed to substantially match the surface shape of the upper wall 104a of the fourth cover body 101D, the side wall portion 113b is formed to substantially match the upper surface shape of the side wall 104b of the fourth cover body 101D, and the front wall portion 113c is formed to substantially match the upper surface shape of the front wall 104c of the fourth cover body 101D.

[0041] As shown in Figure 11, the extended wall portion 113d has a portion 113d1 that extends downward from the left end and rear end of the upper wall portion 113a, a portion 113d2 that extends to the left from the rear end of the side wall portion 113b, and a portion 113d3 that extends rearward from the left end of the front wall portion 113c. As shown in Figures 12 and 13, with the fuel filler cover 113 closed, the lower end of the side wall portion 113b, the lower end of the front wall portion 113c, and the end of the extended wall portion 113d in the extending direction abut against the opening periphery portion 110.

[0042] As shown in Figure 11, a cam lock 114 is provided at the rear of the side wall portion 113b. The cam lock 114 is a lock in which a metal plate called a cam 114b is attached to a cylinder 114a, and the cam 114b moves when a key is inserted into the keyhole 114c (see Figure 6) and turned, allowing the lock to be locked and unlocked. As shown in Figure 13, when the fuel filler cover 113 is closed over the opening 108, the cam lock 114 abuts (engages) with the engaging portion 110a on the right edge of the opening periphery portion 110, restricting the fuel filler cover 113 from rotating in the opening direction.

[0043] As shown in Figures 13 and 14, the fuel filler cover 113 is supported by the fourth cover body 101D via a hinge 115. The hinge 115 supports the fuel filler cover 113 so that it can rotate up and down. The fuel filler cover 113 opens and closes the opening 108 by rotating up and down. Specifically, the fuel filler cover 113 opens the opening 108 as shown in Figure 14 by rotating it upward from the closed position of the opening 108 shown in Figure 13.

[0044] As shown in Figures 10A and 13, the hinge 115 is positioned adjacent to the fuel filler port 96A in the aircraft width direction (horizontal direction). Specifically, the hinge 115 is positioned to the left of the fuel filler port 96A. As mentioned above, the fuel filler port 96A is inclined in a direction that shifts to the right as it goes upwards. That is, the fuel filler port 96A is formed in a sloping shape that shifts away from the hinge 115 as it goes upwards. In other words, as shown in Figure 13, the fuel filler port 96A is formed in a sloping shape such that the opening surface 96Aa faces away from the hinge 115. This makes it possible to suppress the hinge 115 from getting in the way when refueling. It also allows for a wider area for positioning the hinge 115.

[0045] As shown in Figure 13, the hinge 115 has a pivot 116 and a hinge arm 117. The pivot 116 is provided on the inner surface side of the main cover (main wall portion) 104 of the fourth cover body 101D near the opening 108. In this embodiment, the pivot 116 is provided on the lower surface of the upper wall 104a of the fourth cover body 101D near the opening 108.

[0046] As shown in Figure 15, the pivot 116 includes a support base 118 fixed to the lower surface of the upper wall 104a of the fourth cover body 101D, a pivot 119 supported by the support base 118, and a rotating cylinder 120 rotatably fitted onto the pivot 119. The support base 118 has a pair of support pieces 118a facing each other in the front-rear direction along the upper wall 104a of the fourth cover body 101D, and a connecting portion 118b connecting the pair of support pieces 118a. The pivot 119 is provided across the pair of support pieces 118a. The rotating cylinder 120 is positioned between the pair of support pieces 118a and is externally fitted onto the pivot 119 so as to be rotatable around its axis (rotation axis 119a).

[0047] The hinge arm 117 is formed by bending a strip of material, as shown in Figure 10A. The hinge arm 117 has a base portion 117a, a tip portion 117b, a contact portion 117c, and an intermediate arm portion 117d, as shown in Figure 13. The base portion 117a is fixed to the rotating cylinder 120. In other words, the base portion 117a is rotatably supported by the pivot portion 116. The tip portion 117b is fixed to a bracket member 121 which is fixed to the inner surface (lower surface of the upper wall portion 113a) of the fuel filler cover 113. In other words, the tip portion 117b is fixed to the fuel filler cover 113. The contact portion 117c is formed by extending from the base portion 117a. One end of the intermediate arm portion 117d is connected to the contact portion 117c, and the other end is connected to the tip portion 117b.

[0048] As shown in Figure 13, when the fuel filler cover 113 is rotated upward from a state where the fuel filler cover 113 is closed over the opening 108, the contact portion 117c contacts the opening periphery 110 from the inside of the machine body 2, as shown in Figures 10A, 10B, and 14, to open the fuel filler cover 113, thereby restricting the rotation of the fuel filler cover 113 in the opening direction. As shown in Figures 10A and 10B, the portion of the opening periphery 110 that the contact portion 117c contacts is designated as the contacted portion 111. To restrict the rotation of the fuel filler cover 113 in the opening direction, the contact portion 117c could be configured to directly contact the contacted portion 111, but in this embodiment, the contact portion 117c contacts the contacted portion 111 via an elastic member 112 provided on the contacted portion 111. The elastic member 112 is mainly composed of an elastic material such as rubber, and in this embodiment, the elastic member 112 is composed of a trim. The trim is an edge trim with a U-shaped cross-section containing a core metal, and is attached by sandwiching the opening periphery 110. Note that the elastic member 112 does not have to be a trim, and may be, for example, an elastic plate, an elastic block, etc. In this case, the elastic member 112 is attached to the lower surface of the contact portion 111.

[0049] Furthermore, the elastic member 112 may be provided on the contact portion 117c instead of the contacted portion 111. Moreover, the elastic member 112 may be provided on both the contacted portion 111 and the contact portion 117c. In other words, the elastic member 112 only needs to be provided on at least one of the contacted portion 111 and the contact portion 117c.

[0050] When an elastic member 112 is provided on the contact portion 117c, for example, the elastic member 112 is formed of an elastic plate, an elastic block, etc., and is attached to the surface of the contact portion 117c that comes into contact with the contacted portion 111.

[0051] Furthermore, when the fuel filler cover 113 is opened, the contact portion 111 that the contact portion 117c makes contact with (via the elastic member 112) does not need to be located on the opening periphery 110. In other words, the contact portion 111 may be located near the opening periphery 110 (for example, on the connecting portion 137, etc.).

[0052] As shown in Figure 10C, the length L1 of the contact portion 111 corresponds to the width W1 of the hinge arm 117 (contact portion 117c). However, it is not limited to this. Furthermore, the elastic member 112 is formed to a length corresponding to the length L1 of the contact portion 111. However, it is not limited to this, and the length of the elastic member 112 may be longer or shorter than the length L1 of the contact portion 111.

[0053] Furthermore, the trim, which is an elastic member 112, only needs to be attached to at least the portion of the opening periphery 110 that corresponds to the contact portion 111.

[0054] Figure 10D shows a modified example in which an elastic member 112, which is a trim, is provided. As shown in Figure 10D, the elastic member 112, which is a trim, is provided continuously from the middle of the right edge of the opening periphery 110 to the front edge → left edge → rear edge, leaving the engaging portion 110a which is the rear of the right edge of the opening periphery 110.

[0055] Furthermore, if the trim, which is an elastic member 112, is provided only on the portion of the opening periphery 110 corresponding to the contact portion 111, it is preferable to appropriately form a bent portion 110b, which is formed by bending the end side of the opening periphery 110 inward, on the portion of the opening periphery 110 other than the contact portion 111, as shown in Figure 10E, so that the edge of the opening periphery 110 is less likely to be touched by hand.

[0056] Furthermore, as shown in Figure 14, the contact portion 117c contacts the contacted portion 111 via the elastic member 112 (or directly) when the load of the fuel filler cover 113 acts in a direction that rotates the fuel filler cover 113 in the opening direction. Therefore, the contact portion 117c contacts the contacted portion 111 (elastic member 112), thereby holding the fuel filler cover 113 in the open position. In other words, instead of providing a separate stopper to hold the fuel filler cover 113 in the open position, the opening periphery portion 110 that forms the opening 108 is used to hold the fuel filler cover 113 in the open position. This allows the opening of the fuel filler cover 113 to be restricted and the fuel filler cover 113 to be held in the open position while suppressing an increase in the number of parts. In addition, the contact portion 117c is formed in a flat shape that contacts the contacted portion 111 (elastic member 112) surface-to-surface. Furthermore, when the fuel filler cover 113 is open, there is a gap between the fuel filler cover 113 and the upper surface of the fourth cover body 101D, so the fuel filler cover 113 does not come into contact with the fourth cover body 101D. Also, when the work machine 1 is tilted at a predetermined angle upward to the left relative to the horizontal (the work machine 1 is parked on a slope tilted at a predetermined angle relative to the horizontal) with the fuel filler cover 113 open, the opening angle is set so that the fuel filler cover 113 does not close. The tilt angle of the work machine 1 (the tilt angle of the slope) in this case is, for example, 15° to 17°. However, it is not limited to this.

[0057] As shown in Figure 13, the fuel filler cover 113 is in the state where the opening 108 is closed, and the hinge arm 117 To describe its shape, the base portion 117a has its right end fixed to the lower end of the rotating cylinder 120 and extends to the left from the rotating cylinder 120. The contact portion 117c extends from the left end of the base portion 117a in an inclined direction that gradually moves downward as it moves to the left. The intermediate arm portion 117d is formed in a convex curved or bent shape or a curved shape centered on the rotating axis 119a, moving away from the rotation axis 119a of the hinge 115, and extends from the lower end of the contact portion 117c (the lower side of the upper wall 104a) past the lower part of the contacted portion 111 to the lower side of the fuel filler cover 113 and connects to the tip portion 117b.

[0058] In other words, when the fuel filler cover 113 is closed over the opening 108, one end of the intermediate arm portion 117d is connected to the contact portion 117c in the region facing the inner surface of the main cover (main wall portion) 104, the middle portion extends past the region facing the inner surface of the fuel filler cover 113 relative to the contacted portion 111, and the other end is connected to the tip portion 117b in the region facing the inner surface of the fuel filler cover 113.

[0059] Furthermore, as shown in Figure 14, when the fuel filler cover 113 is in the open position of the opening 108, the base portion 117a extends in an inclined direction that shifts downward as it moves from the front of the rotating cylinder 120 to the right. The contact portion 117c extends to the right from the lower end of the base portion 117a and contacts the lower surface of the contacted portion 111 via (or directly) the elastic member 112. The intermediate arm portion 117d extends from the right end of the contact portion 117c to the left in a curved direction centered on the axis of the pivot 119, above the contacted portion 111 (elastic member 112), the opening periphery portion 110, and the upper wall 104a, and is connected to the tip portion 117b.

[0060] In other words, when the fuel filler cover 113 is opened to the point where the contact portion 117c and the contacted portion 111 are in contact, one end of the intermediate arm portion 117d is positioned in the opening 108, and the other end of the intermediate arm portion 117d is positioned in the region of the cover body 101D facing the outer surface of the main cover (main wall portion) 104, and the fuel filler cover 113 is positioned spaced apart from the main cover (main wall portion) 104 in the region of the cover body 101D facing the outer surface of the main cover (main wall portion) 104.

[0061] As shown in Figure 16, the side cover 105 is provided with a storage compartment 122 capable of accommodating the instruction manual 123, which is a printed manual for the work machine 1. Specifically, the storage compartment 122 is located in front of the driver's seat 6 on the side wall portion (side cover 105) of the fourth cover body 101D (cover body) on the driver's seat 6 side. The storage compartment 122 is also located lower than the seat portion 6A. The storage compartment 122 is positioned so that it is easily visible to the operator and does not obstruct the forward view, and so that the operator seated in the driver's seat 6 can easily retrieve it.

[0062] The instruction manual (instruction manual, printed material) 123 is formed, for example, by one or more rectangular cards (leaflets) that are long in the vertical direction (see Figure 20). The instruction manual 123 includes, for example, things that the operator should be aware of before and while operating the work machine 1. Specifically, these include, for example, "read and understand the operator's manual," "confirm that the lock lever that disables the actuators equipped on the work machine 1 is ON when the operator gets on or off the work machine 1," "check the area around the work machine 1," and "fasten the seat belt."

[0063] As shown in Figure 16, the housing 122 is located in front of and below the control device 17R. In other words, the housing 122 is located in front of and below the right control lever 23R. That is, the housing 122 is positioned so as not to interfere with the operation of the right control lever 23R, the dozer lever 35, etc.

[0064] As shown in Figures 16 and 17, the housing section 122 is composed of a side cover (side wall section) 105 and a receiving member 124 fixed to the inner surface (right side) of the side cover 105. More specifically, the housing section 122 is a part of the side cover 105 (side wall section) and includes a housing section forming section 126 in which an insertion opening 125 for inserting an instruction manual (instruction manual, printed material) 123 is formed, and a receiving member 124 fixed to the side of the housing section forming section 126 opposite to the driver's seat 6 side (right side, inner surface) to hold the instruction manual 123 inserted through the insertion opening 125.

[0065] Note that in Figure 17, the area of ​​the housing portion forming portion 126, indicated by the dashed line, is shown for convenience. The storage portion forming portion 126 only needs to include the area in which the insertion opening 125 is formed and the area covering the instruction manual (instruction manual, printed material) 123.

[0066] By making the side cover (side wall portion) 105 a component of the housing portion 122, the structure can be simplified. Furthermore, by providing the receiving member 124 on the side of the side cover 105 opposite to the side facing the driver's seat 6 (inside the fourth cover body 101D), it is possible to prevent a protrusion from being formed on the side of the side cover 105 facing the driver's seat 6.

[0067] As shown in Figures 3, 17, and 18, the side cover 105 has a front first plate portion 105a and a rear second plate portion 105b. The side cover 105 is bent at the connection point between the first plate portion 105a and the second plate portion 105b. Specifically, the second plate portion 105b extends in the front-rear direction, and the first plate portion 105a is formed in a sloping shape that transitions outward (to the right) in the width direction of the machine body as it moves forward from the front end of the second plate portion 105b. The first plate portion 105a has a plurality of mounting portions 127 that are fixed to the main cover 104 of the fourth cover body 101D by bolts or the like (see Figure 17). The mounting portions 127 are attached from the left. The second plate portion 105b has a mounting piece 128 that is fixed to the first cover body 101A by bolts or the like (see Figure 2). The mounting piece 128 is attached from the front.

[0068] As shown in Figure 16, the housing section 122 is located at the rear of the first plate section 105a. Behind the housing section 122 is a variable landing gear lever 129. The variable landing gear lever 129 is a lever that changes the distance (tread) between the first running gear 3L and the second running gear 3R in the width direction of the machine body.

[0069] As shown in Figures 17, 19, and 20, the insertion opening 125 is formed, for example, on the upper part of the storage section forming section 126. The insertion opening 125 is formed in a rectangular shape that is long in the front-to-back direction. The width of the insertion opening 125 in the front-to-back direction is wider than the width of the instruction manual 123. The insertion opening 125 is formed by the surrounding wall portion (peripheral wall portion) 130 of the side cover 105. The peripheral wall portion 130 has an upper side wall portion 130a, a lower side wall portion 130b, a front side wall portion 130c, and a rear side wall portion 130d. The upper side wall portion 130a is the wall portion that constitutes the area above the insertion opening 125. The lower side wall portion 130b is the wall portion that constitutes the area below the insertion opening 125, and the front side wall portion 130c is the wall portion that constitutes the area in front of the insertion opening 125. The rear side wall portion 130d is a wall portion that forms the rear of the insertion opening 125. The upper side wall portion 130a, the lower side wall portion 130b, the front side wall portion 130c, and the rear side wall portion 130d are interconnected.

[0070] As shown in Figures 21 and 22, the upper side wall portion 130a is formed in a sloping shape that transitions downwards towards the main wall portion 124a (to the right), as described later. The lower side wall portion 130b is formed in a sloping shape that transitions upwards towards the main wall portion 124a (to the right). The vertical dimension of the upper side wall portion 130a is larger than the vertical dimension of the lower side wall portion 130b. Also, the lower end of the upper side wall portion 130a is located closer to the main wall portion 124a than the upper end of the lower side wall portion 130b.

[0071] The upper side wall portion 130a can be used as a guide to guide the insertion of the instruction manual 123 through the insertion opening 125. By using the upper side wall portion 130a as a guide when inserting the instruction manual 123, it is possible to prevent the instruction manual 123 from getting caught on the lower side wall portion 130b.

[0072] As shown in Figure 23, the front side wall portion 130c is formed in a sloping shape that transitions towards the main wall portion 124a (to the right) as it moves towards the rear. The rear side wall portion 130d is formed in a sloping shape that transitions towards the main wall portion 124a (to the right) as it moves towards the front.

[0073] In the surrounding wall portion 130, the upper side wall portion 130a, the lower side wall portion 130b, the front side wall portion 130c, and the rear side wall portion 130d are inclined toward approaching the main wall portion 124a, so that the edge of the insertion opening 125 does not protrude from the surface side of the side cover 105 on the driver's seat 6 side.

[0074] The receiving member 124 is formed from a metal plate (sheet metal). It may also be formed from a resin plate. As shown in Figures 7 and 19, the side cover 105 (housing part forming part 12 6) is adjacent to the fuel tank 96 in the width direction of the aircraft body, and the receiving member 124 is provided between the fuel tank 96 and the side cover 105 (housing section forming section 126).

[0075] As shown in Figure 24, the receiving member 124 has a main wall portion 124a, a lower wall portion 124b, an upper wall portion 124c, a front wall portion 124d, and a rear wall portion 124e. The main wall portion 124a is positioned opposite the side cover 105 (housing portion forming portion 126) with a gap in the width direction of the machine body. Furthermore, the upper part of the main wall portion 124a is positioned opposite the insertion opening 125 and the upper side wall portion 130a in the width direction of the machine body (see Figure 21). In addition, the main wall portion 124a is formed with a front-to-back width extending from the front side wall portion 130c to the rear side wall portion 130d (see Figure 23).

[0076] As shown in Figure 19, the lower wall portion 124b extends integrally from the lower end of the main wall portion 124a toward the side cover 105 (housing portion forming portion 126). The extended end of the lower wall portion 124b is fixed to the side cover 105 (housing portion forming portion 126) by welding or the like. The upper wall portion 124c extends integrally from the upper end of the main wall portion 124a toward the side cover 105 (housing portion forming portion 126). The extended end of the upper wall portion 124c is fixed to the side cover 105 (housing portion forming portion 126). More specifically, the extended end of the upper wall portion 124c is fixed to the upper part of the upper side wall portion 130a by welding or the like.

[0077] As shown in Figure 23, the front wall portion 124d extends integrally from the front end of the main wall portion 124a toward the side cover 105 (housing portion forming portion 126). The extended end of the front wall portion 124d is fixed to the side cover 105 (housing portion forming portion 126). More specifically, the extended end of the front wall portion 124d is fixed to the front of the front side wall portion 130c by welding or the like. The rear wall portion 124e extends integrally from the rear end of the main wall portion 124a toward the side cover 105 (housing portion forming portion 126). The extended end of the rear wall portion 124e is fixed to the side cover 105 (housing portion forming portion 126). More specifically, the extended end of the rear wall portion 124e is fixed to the rear of the rear side wall portion 130d by welding or the like.

[0078] In the above-mentioned receiving member 124, the upper part of the main wall portion 124a is positioned to face the insertion opening 125 and the upper side wall portion 130a in the machine width direction, and the front-to-back width of the main wall portion 124a is formed to extend from the front side wall portion 130c to the rear side wall portion 130d. The upper wall portion 124c is fixed to the upper part of the upper side wall portion 130a by welding, the front wall portion 124d is fixed to the front of the front side wall portion 130c by welding, and the rear wall portion 124e is fixed to the rear of the rear side wall portion 130d by welding, thereby reinforcing the area around the insertion opening 125. This makes it possible to suppress the reduction in strength caused by forming an opening in the insertion opening 125.

[0079] Furthermore, the lower wall portion 124b, upper wall portion 124c, front wall portion 124d, and rear wall portion 124e are formed by bending the plate material that constitutes the receiving member 124. By forming the receiving member 124 by bending the plate material and welding it to the side cover 105, the receiving member 124 can be compactly installed between the fuel tank 96 and the side cover 105.

[0080] However, the shape and configuration of the receiving member 124 are not limited to those described above.

[0081] As shown in Figures 19 and 20, the insertion opening 125 of the storage section 122 is formed at a height position such that, when the instruction manual (manual, printed material) 123 is stored inside the storage section 122 and its lower end is in contact with the lower wall 124b, the instruction manual 123 protrudes upward from the insertion opening 125. When the instruction manual 123 is stored inside the storage section 122, the upper end of the instruction manual 123 is located above the upper side wall 130a. Therefore, when the instruction manual 123 is stored inside the storage section 122, a gap is created between the upper end of the instruction manual 123 and the side cover 105. As a result, when removing the instruction manual 123 from the storage section 122, a finger can be hooked onto the upper end of the instruction manual 123 to separate it from the upper side wall 130a, and the top of the instruction manual 123 can be easily grasped. Furthermore, the instruction manual 123 can be separated from the upper side wall 130a by hooking a finger into the parts corresponding to the front and rear insertion openings 125 of the instruction manual 123. In addition, the instruction manual 123 can be removed by grasping the string member 132, which will be described later, and pulling it upwards.

[0082] As shown in Figure 20, the space between the front end of the lower wall portion 124b and the lower end of the front wall portion 124d, and the lower wall A gap (drainage section) 136 is provided between the rear end of section 124b and the lower end of the rear wall section 124e, which allows water that has entered the housing section 122 (for example, water that has entered between the side cover 105 and the main wall section 124a from the insertion opening 125) to drain out. The gap only needs to be provided between the front end of the lower wall section 124b and the lower end of the front wall section 124d, and between the rear end of the lower wall section 124b and the lower end of the rear wall section 124e.

[0083] As shown in Figure 16, the side cover 105 is provided with a string member 132, one end of which is attached to the front of the side cover 105 by a fastener 131 such as a screw or rivet. The other end of the string member 132 is connected to the instruction manual (instruction manual, printed material) 123. More specifically, as shown in Figure 25, an annular connecting portion 133 is formed on the other end of the string member 132, making the string member 132 into a loop. A hole 134 is formed in the upper corner of the instruction manual 123. The other end of the string member 132 is connected to the instruction manual 123 by passing a ring member 135 through the annular connecting portion 133 and the hole 134.

[0084] Figures 26, 27, 28, and 29 show other examples of the side cover 105. Figure 26 is a left side view of the side cover 105, Figure 27 is a perspective view of the left side of the side cover 105 seen from the front, Figure 28 is a right side view of the side cover 105, and Figure 29 is a perspective view of the right side of the side cover 105 seen from the rear.

[0085] As shown in Figures 26 to 29, the side cover 105 of this other example has a recess (referred to as the first recess) 138 and a recess (referred to as the second recess) 139. The first recess 138 and the second recess 139 are formed by recessing the plate material that constitutes the side cover 105 itself. More specifically, the first recess 138 and the second recess 139 are formed by recessing (creating a recess) the plate material that constitutes the side cover 105 from left to right. Therefore, the first recess 138 and the second recess appear convex when viewed from the right.

[0086] The first recess 138 is formed extending from the rear end of the second plate portion 105b to the middle of the first plate portion 105a. The second recess 139 is formed on the front side of the first recess 138 in the first plate portion 105a. The first recess 138 has a back wall 138a that forms the back surface of the first recess 138, an upper wall 138b along the upper edge of the back wall 138a, a lower wall 138c along the lower edge of the back wall 138a, and a front wall 138d along the front edge of the back wall 138a. The lower part of the front wall 138d extends in the vertical direction, and the upper part of the front wall 138d is formed to protrude forward from the lower part.

[0087] In the side cover 105 of this other example, as shown in Figures 26 and 27, the insertion opening 125 of the housing section 122 is located at the rear of the first plate section 105a and is formed on the upper part of the back wall 138a of the first recess 138. The insertion opening 125 is also formed behind the lower part of the front wall 138d. The receiving member 124 is fixed to the right side of the side cover 105 on the surface corresponding to the back wall 138a of the first recess 138 (the back surface of the back wall 138a), as shown in Figures 28 and 29. Specifically, the upper wall section 124c of the receiving member 124 is positioned near the upper wall 138b of the first recess 138 and is arranged along the upper wall 138b. The front wall section 124d of the receiving member 124 is arranged along the lower part of the front wall 138d of the first recess 138. The lower wall section 124b of the receiving member 124 is arranged along the lower wall 138c of the first recess 138. The rear wall portion 124e of the receiving member 124 is positioned to extend vertically near the rear end of the first plate portion 105a.

[0088] Except as described above, the configuration is the same as that of the above embodiment.

[0089] The work machine 1 of this embodiment described above comprises a machine body 2, at least one tank (fuel tank 96, hydraulic oil tank 97) mounted on the machine body 2 and having fuel inlets (fuel inlet 96A, hydraulic oil inlet 97A), and a cover body (fourth cover body 101D) that covers the tanks 96 and 97, the cover body 101 having a main wall portion (main cover 104) and an opening 108 formed in a part of the main wall portion 104 to expose the fuel inlets 96A and 97A. The device comprises a D, a fuel filler cover 113 that opens and closes the opening 108, and a hinge 115 that rotatably supports the fuel filler cover 113. The hinge 115 has a contact portion 117c that, when the fuel filler cover 113 is rotated open, contacts the opening peripheral portion 110 or the contact portion 111 near the opening peripheral portion 110, which is the peripheral edge of the opening 108 in the cover body 101D, from the inside of the machine body 2, thereby restricting the rotation of the fuel filler cover 113 in the opening direction.

[0090] With this configuration, when the fuel filler cover is opened, the contact portion 117c of the hinge 115 contacts the contact portion 111 on the cover body 101D side from the inside of the aircraft body 2, thereby restricting the opening of the fuel filler cover 113.

[0091] Furthermore, the hinge 115 supports the fuel filler cover 113 so that it can rotate up and down, and the contact portion 117c contacts the contacted portion 111 in such a way that the load of the fuel filler cover 113 acts in a direction that causes the fuel filler cover 113 to rotate in the opening direction.

[0092] With this configuration, the fuel filler cover 113 can be held open by its own weight.

[0093] Furthermore, an elastic member 112 is provided on at least one of the contacted portion 111 and the contacted portion 117c, and the contacted portion 117c contacts the contacted portion 111 via the elastic member 112.

[0094] This configuration allows for buffering of contact between the contact portion 117c and the contacted portion 111. Furthermore, the elastic member 112 is a trim attached to at least the portion of the opening periphery 110 that corresponds to the contacted portion 111.

[0095] This configuration allows for easy assembly of the elastic member 112. Furthermore, the hinge 115 has a pivot portion 116 provided on the inner surface side of the main wall portion 104 of the cover body 101D near the opening 108, and a hinge arm 117 including a base portion 117a rotatably supported by the pivot portion 116 and a tip portion 117b fixed to the fuel filler cover 113, and the contact portion 117c is provided between the base portion 117a and the tip portion 117b of the hinge arm 117. This configuration allows the hinge 115 to be positioned closer to the periphery of the opening 108, making the structure of the hinge 115 more compact.

[0096] Furthermore, the hinge arm 117 has a base portion 117a, a contact portion 117c whose base end is connected to the base portion 117a, and an intermediate arm portion 117d whose one end is connected to the tip side of the contact portion 117c and whose other end is connected to the tip side portion 117b. When the fuel filler cover 113 is closed over the opening 108, one end of the intermediate arm portion 117d is connected to the contact portion 117c in a region facing the inner surface of the main wall portion 104, the intermediate portion extends past a region facing the inner surface of the fuel filler cover 113 relative to the contacted portion 111, and the other end is connected to the tip side portion 117b in a region facing the inner surface of the fuel filler cover 113. This configuration allows for a more compact structure for the hinge 115.

[0097] Furthermore, when the fuel filler cover 113 is opened to the point where the contact portion 117c and the contacted portion 111 are in contact, one end of the intermediate arm portion 117d is positioned in the opening 108, and the other end of the intermediate arm portion 117d is positioned in the region facing the outer surface of the main wall portion 104 of the cover body 101D, so that the fuel filler cover 113 is positioned in the region facing the outer surface of the main wall portion 104 of the cover body 101D, spaced apart from the main wall portion 104.

[0098] This configuration allows for a compact design of the hinge 115.

[0099] Furthermore, the hinge 115 is positioned adjacent to the fuel filler port (fuel filler port 96A), and the fuel filler port 96A is formed in an inclined shape such that its opening surface 96Aa faces away from the hinge 115.

[0100] This configuration allows for a wider area for positioning the hinge 115.

[0101] Furthermore, the intermediate arm portion 117d is formed in a convex curved or bent shape in the direction away from the pivot axis 119a of the hinge 115, and the contact portion 117c is formed in a flat shape that contacts the contacted portion 111 with a flat surface.

[0102] This configuration allows the hinge arm 117 to rotate compactly and also securely holds the fuel filler cover 113.

[0103] Furthermore, the cover body 101D has a main wall portion 104, an opening peripheral portion 110, and a connecting portion 137 that connects the main wall portion 104 and the opening peripheral portion 110. The connecting portion 137 is formed by bending or curving inward from the main wall portion 104, and the contact portion 111 is formed at a position inward from the main wall portion 104 on the opening peripheral portion 110 or the connecting portion 137. This configuration allows for a compact design of the hinge 115.

[0104] Furthermore, the work machine 1 comprises a machine body 2, a driver's seat 6 mounted on the machine body 2, a cover body 101D that covers the loads mounted on the machine body 2 (fuel tank 96, hydraulic oil tank 97) and is provided to the side of the driver's seat 6 so as to extend forward from the driver's seat 6, and a storage section 122 for storing printed materials (instruction manual 123). The storage section 122 is provided in front of the driver's seat 6 and on the side wall portion (side cover 105) of the cover body 101D on the driver's seat 6 side.

[0105] With this configuration, printed materials 123 such as instruction manuals can be easily grasped and retrieved by the operator.

[0106] Furthermore, the aircraft is equipped with a control device 17R located to the side of the driver's seat 6 and for operating the work device 4 located on the aircraft body 2, and the storage compartment 122 is located in front of and below the control device 17R.

[0107] This configuration allows the housing section 122 to be positioned in a location that does not interfere with the operation of the control device 17R.

[0108] Furthermore, the storage section 122 is part of the side wall (side cover 105) and includes a storage section forming section 126 in which an insertion opening 125 for inserting printed material 123 is formed, and a receiving member 124 fixed to the side of the side wall 105 opposite to the driver's seat 6 side and holding the printed material 123 inserted through the insertion opening 125.

[0109] This configuration prevents the formation of a protrusion on the driver's seat 6 side of the side cover (side wall portion) 105.

[0110] Furthermore, the receiving member 124 has a main wall portion 124a that is positioned opposite to the side wall portion 105 with a gap in the width direction of the machine body, and a lower wall portion 124b that extends from the lower end of the main wall portion 124a toward the side wall portion 105 and is fixed to the side wall portion 105.

[0111] With this configuration, the main wall portion 124a can prevent the printed material 123 from falling to the back, and the lower wall portion 124b can hold the printed material 123 in place.

[0112] Furthermore, the storage section forming section 126 has an upper side wall section 130a which is a wall section that constitutes the area above the insertion opening 125, and the upper side wall section 130a is formed in an inclined shape that moves towards the main wall section 124a as it goes downwards.

[0113] With this configuration, the upper side wall portion 130a can be used as a guide to guide the insertion of the printed material 123 when it is inserted through the insertion slot 125.

[0114] The receiving member 124 is provided between the side wall portion 105 and the load (fuel tank 96) housed within the cover body 101D so as to be adjacent to the side wall portion 105 in the aircraft width direction.

[0115] This configuration allows for effective use of the space between the mounted object 96 and the side wall portion 105.

[0116] Furthermore, the receiving member 124 has a front wall portion 124d that extends from the front end of the main wall portion 124a toward the side wall portion 105 and is fixed to the side wall portion 105, and a rear wall portion 124e that extends from the rear end of the main wall portion 124a toward the side wall portion 105 and is fixed to the side wall portion 105, and a gap is provided in at least one of the following locations: between the front end of the lower wall portion 124b and the lower end of the front wall portion 124d, and between the rear end of the lower wall portion 124b and the lower end of the rear wall portion 124e, in which water that has entered the housing portion 122 can be drained.

[0117] This configuration allows water that has entered the containment section 122 to be drained. Furthermore, the work machine 1 is open to the outside, as the area around the driver's seat 6 is not enclosed by walls.
