Abstract
To provide a handle equipped with a torque limiter capable of preventing application of excessive torque, and a fluid controller provided with the same. An elastic body (7) has a minimum-urging force capable of developing a function desired when the handle is lowered to the lowest position. Disposed in the handle are a transmitting member (8) urged by the elastic body and a transmitted material (10) against which the lower surface of the transmitting material is pressed. The surface of the transmitted material opposed to the transmitting material or the surface of the transmitting material opposed to the transmitted material is formed with serrations along the periphery having inclined surfaces (81, 101) and vertical surfaces (82, 102) which alternately appear. The inclined surfaces of the serrations are upwardly tapered along the direction of rotation in which the cover body descends.
