Abstract

A work vehicle includes: a vehicle body to which a work machine is connected at a back, a roll-over protection structure frame that, in the vehicle body, is erected in a back part of a drive seat, a positioning unit that, based on a signal sent from a positioning satellite, detects a position of the vehicle body, and a support unit that is fixed to an upper part of the roll-over protection structure frame, and supports the positioning unit from below. The positioning unit has a harness connection part that is connected with a harness for sending information to outside. The harness connection part is positioned in a back part of the positioning unit. The support unit is so positioned as to protrude behind the harness connection part of the positioning unit.

Claims (30)

1 . A work vehicle comprising:

a vehicle body to which a work machine is connected at a back; and

a roll-over protection structure frame that, in the vehicle body, is erected in a back part of a drive seat,

wherein

the work vehicle further comprises:

a positioning unit that, based on a signal sent from a positioning satellite, detects a position of the vehicle body, and

a support unit that is fixed to an upper part of the roll-over protection structure frame, and supports the positioning unit from below, and

the positioning unit has a harness connection part that is connected with a harness for sending information to outside,

the harness connection part is positioned in a back part of the positioning unit, and

the support unit is so positioned as to protrude behind the harness connection part of the positioning unit.

2 . The work vehicle as claimed in claim 1 , wherein

the harness connection part is so positioned as to protrude backward from a back face of the positioning unit.

3 . The work vehicle as claimed in claim 1 , wherein

the harness connection part is positioned behind the roll-over protection structure frame.

4 . The work vehicle as claimed in claim 1 , wherein

the support unit has:

a support member that supports the positioning unit, and

a protective member mounted to the support member, and

the protective member is mounted to a back part of the support member and extends in a right/left direction.

5 . The work vehicle as claimed in claim 4 , wherein

the protective member has a shape that extends forward from each of right and left end parts of a back part of the support member along respective right and left edges of the support member, and that connects in front of the roll-over protection structure frame and in the right/left direction in a position below the support member.

6 . The work vehicle as claimed in claim 1 , further comprising:

a first fixing member that, to the support unit, fixes part of the harness connected to the harness connection part.

7 . The work vehicle as claimed in claim 6 , further comprising:

a second fixing member that fixes the part of the harness to an outer surface of the roll-over protection structure frame.

8 . The work vehicle as claimed in claim 1 , wherein

the support unit has a support member that supports the positioning unit, and

the support member has a notch part below the harness connection part.

9 . The work vehicle as claimed in claim 8 , wherein

the support unit further has a mount stay that is depressed downward through an inside of the notch part, and is fixed to the support member.
