Claims (1)

[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 mounted on the rotation unit, 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 provided 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 offset to the elevation axis on the rotating part.
The radar is configured to be connected via a connecting rod to a pivot of an antenna section provided in the antenna, and the antenna is driven up and down by vertical movement converted from a swinging motion through a grooved cam and a cam roller. Device.
