There is provided a torque limiter in which oil in an oil pressure expanding chamber can be rapidly removed, when an inner peripheral face of a tube member has slipped with respect to an outer peripheral face of a shaft member, and burn-outs are unlikely to occur on the shaft member and the tube member. An area of a region where an inner face of a circumferentially extending chamber 38 intersects an oil pressure expanding chamber 26 in an extended plane extended toward the oil pressure expanding chamber 26 is made larger than a sectional area of an opening of an oil removing hole which is opened to the circumferentially extending chamber 38.
