Claims

[Claims for Utility Model Registration] A rotary table 52 is connected to a fixed base 51 via a vertical shaft 53.
A seat 56 is height-adjustably mounted on the rotary table 52 via a stay 55, and a fixing mechanism 54 is provided for pressing the rotary table 52 against the base 51 to prevent rotation. In the seat device, the fixing mechanism 54 has a horizontal shaft 6 passing through the vertical shaft 53.
8, an eccentric cam 69 that is fitted onto the horizontal shaft 68 and can be pressed against the rotary table 52, a rotating shaft 71 that is parallel to the horizontal shaft 68 and is attached to the eccentric cam 69, and the eccentric cam 69. It has a handle 70 that is attached to a rotation shaft 71 and extends upward for rotation, and a guide 62a for resting the rotation shaft 71 on the rotation table 52, and a handle 70 for supporting the rotation shaft 71. A fixing mechanism for a rotary seat device, characterized in that a stopper 62b for setting an operating range is formed.
