。 a driven part consisting of a rotatable driven shaft and a friction part fixed to the drive side end of the driven shaft;
A hollow drive shaft that is arranged coaxially with the driven shaft and is constantly rotated so that the fluid moves therein; and a bag-shaped bag that is fixed to the driven end of the drive shaft and that the fluid contacts inside. It is equipped with a temperature sensing part and a driving part consisting of a pressing part that is fixed to the outside of the temperature sensing part and can come into contact with and separate from the friction part, and the temperature sensing part is made of a shape memory alloy and contracts at room temperature and presses. A temperature-sensitive clutch characterized in that a portion is spaced apart from a friction portion and expands when a fluid temperature within the temperature-sensing portion exceeds a predetermined value so that the pressing portion comes into contact with the friction portion.
