PROBLEM TO BE SOLVED: To provide a rotary support device in which the angle of inclination of a movable member can be easily adjusted without increasing the number of components. SOLUTION: In an antenna device, antenna members 3A and 3B are provided with the angles of the antenna members 3A and 3B adjustable with respect to a support 2. The antenna members are provided with a rotary part 13 at the bottom 13, wherein the rotary part 13 is supported rotatably by a receiving part of the support 2. The rotary part 13 has first parts 13A and 13B which are elastically deformable in a sectorial and hollow frame shape, wherein a plurality of engagement grooves are formed, and second sectorial parts 13CA and 13CB having a slit S from the first parts 13A and 13B. In the support 2, an opening 2a into which the rotary part 13 is inserted is formed at an upper part, and a shaft is provided on left and right inner walls in the opening 2a. The shaft is inserted into the slit S between the first parts 13A and 13B and the second parts to be a rotary center of the rotary part 13 when the shaft is inserted. COPYRIGHT: (C)2006,JPO&NCIPI
