Document Type and Number:
Japanese Patent JPH1197920
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To easily perform antenna rotation fine adjustment and screw clamping operation on a vertical plane and to sufficiently guarantee the fixation function of the antenna. SOLUTION: This angle adjusting device is equipped with a horizontal angle adjusting member 2 which has a receiving surface 2a for an external spherical surface and is rotatably on a horizontal plane and a vertical angle adjusting member 3 which has a receiving surface 3a opposite the receiving surface 2a of the horizontal angle adjusting member 2 and is able to slant on the vertical plane by rotation on the axis of the receiving surface 3a, and varies the angle of rotation of an antenna holding member 4 on the horizontal plane and vertical plane, and the vertical angle adjusting member 3 of this angle adjusting device 1 is clamped to the antenna holding member 4 so that it freely moves forward and backward through the horizontal angle adjusting member 2.
