PURPOSE: To secure a tripod head that is high in the degree of stability by forming both first and second rotation symmetrical bodies into being somewhat flatness each in type and rotated perpendicularly to each other, and clamping each with a fastening device. CONSTITUTION: A first rotation body 3 is rotatably attached to a hollow shaft 10 as the center, and a second rotation body 4 crosswise to this hollow shaft 10, respectively. When a rotary knob 21 is turned round, slide members 18 move in the radially outward direction with each other and subject to a wedge action with a supporting ring 17, pressing a clamping member 16 to the first rotation body 3 for locking or loosening. Likewsie the second rotation body 4 is locked by a rotary knob 30. Since these two rotation bodies are formed into a flat spheroid each, the range of contacting with the clamping member is enlarged in proportion as increasing a turning angle of the rotation body, so that an clamping effect grows larger. Thus, a tripod head being high in the degree of clamping stability is securable. |
