## Abstract

An antenna attachment structure attaches a plurality of antennas to a dump truck including a chassis and a dump body rotatably provided on the chassis, the dump body covering the chassis across an entire length and entire width thereof in a plan view. The antenna attachment structure includes: an antenna attachment portion to which the plurality of antennas are attached and rotatably attached to each of lateral surfaces of the dump body; and a parallel link mechanism including the antenna attachment portion and a rotation center of the dump body and configured to keep a constant posture of the antenna attachment portion when the dump body is rotated.

## Claims

### Claim 1

An antenna attachment structure attaching a plurality of antennas to a dump truck comprising a chassis and a dump body rotatably provided on the chassis, the dump body covering the chassis across an entire length and entire width thereof in a plan view,
the antenna attachment structure comprising:
an antenna attachment portion to which the plurality of antennas are attached and the antenna attachment portion being rotatably attached to a lateral surface of the dump body; and
a parallel link mechanism comprising the antenna attachment portion and a rotation center of the dump body and configured to keep a constant posture of the antenna attachment portion when the dump body is rotated.

### Claim 2 (depends on 1)

The antenna attachment structure according to claim 1, wherein
the antenna attachment portion is attached to a lateral surface of a side of the dump body from which loads are dumped.

### Claim 3 (depends on 1)

The antenna attachment structure according to claim 1, wherein
the parallel link mechanism comprises a link rod comprising: a first end rotatably attached to the antenna attachment portion; and a second end rotatably attached to the chassis at a position offset from the rotation center of the dump body in an opposite direction from an end of a side of the dump body from which loads are dumped.

### Claim 4 (depends on 1)

A dump truck comprising the antenna attachment structure according to claim 1.

### Claim 5 (depends on 4)

The dump truck according to claim 4, wherein
the antenna attachment structure is attached to each of lateral surfaces of the dump body.

### Claim 6 (depends on 4)

The dump truck according to claim 4, wherein
the antenna attachment portion comprises: an attachment body to which the plurality of antennas are attached; and an extension extending downward from the attachment body, and
the plurality of antennas are positioned apart from an end of a side of the dump body from which loads are dumped and project beyond an upper end of the dump body.
