The drip rail 60 is a drain rail member for draining rainwater and the like. The drip rail 60 has a cross-sectional shape that can store water flowing into the drip rail 60 from above. The cross-sectional shape of the drip rail 60 is, for example, a U-shape. The water accumulated in the drip rail 60 is discharged from the front end 60a or the rear end 60b of the drip rail 60. By providing the drip rail 60 on the side surfaces 5 and 6, it is possible to prevent rainwater from entering the vehicle compartment 3 when the side windows 5a and 6a are opened. The drip rail 60 is provided along the front-rear direction of the cab 1. The drip rail 60 is connected to the roof panel 10 and the side panel 20.
The drip rail provided on the side surface 6 has the same configuration as the drip rail 60 provided on the side surface 5.

<Drip rail configuration in the length direction>
As shown in FIG. 2, the drip rail 60 extends in the front-rear direction on the side surface 5 above the side window 5a. In the following description, a portion of the drip rail 60 provided on the side surface 5 that is positioned forward of the rear end of the side window 5a is referred to as a front portion 61, and a portion that is positioned rearward of the rear end of the side window 5a. Is referred to as the rear portion 63.

  A front end 60 a of the drip rail 60 is formed in the front portion 61. A rear end 60 b of the drip rail 60 is formed on a back surface portion 65 that communicates with the rear portion 63. The back surface portion 65 is provided on the back surface 7 of the cab 1 and will be described in detail later.

  By the way, when the front end 60a is located in the vicinity of the front window 4a of the front surface 4 of the cab 1, water discharged from the front end 60a may be applied to the front window 4a. When water is applied to the front window 4a, the driver's view from the cab 1 is deteriorated. In view of such a problem, the rear portion 63 of the drip rail 60 according to the present embodiment has a rear inclined portion 64.

  The rear inclined portion 64 is a portion of the rear portion 63 that is displaced downward toward the rear. Since the rear portion 63 has the rear inclined portion 64, the water accumulated on the drip rail 60 can easily move rearward. For this reason, since discharge of the water from the front end 60a of the drip rail 60 can be suppressed, it can suppress that the driver | operator's visual field from the cab 1 deteriorates due to the water discharged | emitted from the front end 60a.

  Preferably, as shown in FIG. 2, the point P <b> 2 positioned at the lowermost position in the rear inclined portion 64 is more than the point P <b> 1 positioned at the lowermost position in the portion of the drip rail 60 positioned in front of the rear inclined portion 64. Located below. By doing in this way, the water collected on the drip rail 60 is discharged from the rear end 60b through the rear inclined portion 64 at a higher ratio.

  Preferably, the angle θ2 formed by the rear inclined portion 64 with respect to the horizontal direction H is larger than the angle formed by the portion located in front of the rear inclined portion 64 with respect to the horizontal direction H. For example, the front portion 61 may have a front inclined portion 62 that is displaced downward as it goes forward. In this case, an angle θ2 formed by the rear inclined portion 64 with respect to the horizontal direction H is larger than an angle θ1 formed by the front inclined portion 62 with respect to the horizontal direction H. Also by doing in this way, the water accumulated on the drip rail 60 is discharged from the rear end 60b through the rear inclined portion 64 at a higher ratio. An angle θ2 formed by the backward inclined portion 64 with respect to the horizontal direction H is, for example, 45 °.

<Drip rail configuration in the width direction>
FIG. 3 is a schematic diagram of the AA cross section of FIG. The drip rail 60 has a rail portion 71, a wall portion 72, and a side facing portion 73. The drip rail 60 is joined to the side panel 20 by welding or the like, and is joined to the side surface portion 12 of the roof panel 10 by welding or the like.

  The rail portion 71 is provided such that the length direction is substantially along the front-rear direction of the cab 1. For example, rainwater falling along the roof panel 10 flows along the length direction of the rail portion 71 and is discharged at the front end 60 a or the rear end 60 b of the drip rail 60. The rail portion 71 is joined to the side surface portion 12 of the roof panel 10.

  The wall portion 72 is a wall bent from one end of the rail portion 71 in the width direction (Y direction in FIG. 3), and is provided along the length direction of the rail portion 71. By providing the wall portion 72, rainwater can be prevented from overflowing from the rail portion 71.

  The side facing portion 73 is bent from the other end in the width direction of the rail portion 71 and faces the side panel 20. The side facing portion 73 is provided along the length direction of the rail portion 71. The side facing portion 73 is joined to the side panel 20.

<Back part>
Hereinafter, the configuration of the drip rail 60 in the length direction will be further described. FIG. 4 is a perspective view showing the side surface 5 and the back surface 7 of the cab 1. The drip rail 60 further includes a back surface portion 65 provided on the back surface 7 along the vehicle width direction of the cab 1. The back surface portion 65 communicates with a rear portion 63 provided on the side surface 5. Further, the back surface portion 65 includes a rear end 60 b of the drip rail 60. For this reason, the water that has passed through the rear inclined portion 64 of the rear portion 63 passes through the rear portion 65 and is discharged at the rear end 60b. By providing such a back surface portion 65, the water accumulated on the drip rail 60 can be discharged from the back surface 7.

  FIG. 5 is a rear view showing the rear surface 7 of the cab 1. The cab 1 further includes an operation member 7 b provided on the back surface 7 below the back surface portion 65 of the drip rail 60. The operation member 7b is a member for operating the cab 1, for example, an operation lever used when the driver performs an operation for tilting the cab 1 with respect to the vehicle body frame. The operation member 7b is provided in the area | region of the back surface 7 and the vicinity of the side surface 5, for example, is formed in the part located in the back surface 7 among the side panels 20. FIG.

  Preferably, the rear end 60b of the back surface portion 65 of the drip rail 60 positioned above the operation member 7b is located farther from the side surface 5 than the operation member 7b in the vehicle width direction of the cab 1. By doing in this way, it can suppress that the water discharged | emitted from the rear end 60b applies to the operation member 7b.

  Preferably, an angle θ3 formed by the back surface portion 65 with respect to the horizontal direction H is smaller than an angle θ2 formed by the rear inclined portion 64 with respect to the horizontal direction H. For example, when the angle θ2 is 30 ° or more, the angle θ3 is 10 ° or less. By configuring the back surface portion 65 in this manner, the water discharge direction can be made closer to the horizontal direction H, so that it is difficult for water to be applied to the operation member 7b. In addition, since the rear inclined portion 64 is provided in the front stage of the back surface portion 65, the movement of water is accelerated by the rear inclined portion 64, and the horizontal velocity component of water when discharged from the rear end 60b. The absolute value of can be increased. By these things, water can move more in the horizontal direction until the water discharged from the rear end 60b reaches the same position as the operation member 7b in the vertical direction. This can have an effect of suppressing the water discharged from the rear end 60b from being applied to the operation member 7b.

<Effect in this embodiment>
Since the drip rail 60 of the cab 1 according to the present embodiment includes the rear inclined portion 64 that is displaced downward toward the rear, the water accumulated on the drip rail 60 is easily moved rearward. For this reason, since discharge of the water from the front end 60a of the drip rail 60 can be suppressed, it can suppress that the driver | operator's visual field from the cab 1 deteriorates due to the water discharged | emitted from the front end 60a.

  Further, the point P2 positioned at the lowest position in the rear inclined portion 64 is positioned below the point P1 positioned at the lowest position in the portion of the drip rail 60 positioned in front of the rear inclined portion 64. By doing in this way, the water collected on the drip rail 60 can be discharged | emitted from the rear end 60b of the back inclination part 64 by a higher ratio.

  Further, since the drip rail 60 further includes a back surface portion 65 provided on the back surface 7 along the vehicle width direction of the cab 1, the water accumulated on the drip rail 60 can be discharged from the back surface 7.

  Further, since the angle θ3 formed by the back surface portion 65 with respect to the horizontal direction H is smaller than the angle θ2 formed by the rear inclined portion 64 with respect to the horizontal direction H, the angle θ2 and the angle θ3 are smaller than when the angle θ2 is the same. Since the discharge direction can be made closer to the horizontal direction H, it is possible to achieve an effect of suppressing the water discharged from the rear end 60b from being applied to the operation member 7b.

  As mentioned above, although this invention was demonstrated using embodiment, the technical scope of this invention is not limited to the range as described in the said embodiment. It will be apparent to those skilled in the art that various modifications or improvements can be added to the above embodiment. It is apparent from the scope of the claims that the embodiments added with such changes or improvements can be included in the technical scope of the present invention.

  For example, in the above-mentioned embodiment, the drip rail 60 has shown the example which has the back surface part 65 containing the rear end 60b. However, as long as the drip rail 60 has the rear inclined portion 64 provided on the side surface 5 of the cab 1, the specific configuration of the drip rail 60 is not particularly limited. For example, the drip rail 60 may not have the back surface portion 65. In this case, the rear end 60b of the drip rail 60 is formed at the rear inclined portion 64, for example.
