Claims

[Scope of utility model registration request]

In a radar device consisting of an antenna that emits radio waves and a drive unit that rotates and raises the antenna, the drive unit drives a rotation axis using a motor fixed to a pedestal, rotates the antenna, and rotates the rotation axis. A grooved cam with an axial center and vertically wavy grooves on the circumference is fixed to the pedestal, and on the other hand,
The rotating movable part is equipped with a cam roller that rolls in the groove of the grooved cam, and the vertical movement caused by rolling in the groove of this cam roller is transferred to the pivot of the antenna part, which is located at a position offset from the elevation axis on the rotating part, with a connecting rod. What is claimed is: 1. A radar device characterized in that the antenna is configured to be connected via a grooved cam and a cam roller, and the antenna elevation and elevation drive is performed by vertical movement converted from a turning movement via a grooved cam and a cam roller.
