A torque limiter comprising: a shaft member (2; 102); and a tubular member rotatably fitted on the shaft member (2; 102), wherein the tubular member has a fluid pressure expansion chamber for pressing an inner peripheral face of the tubular member against an outer peripheral face of the shaft member (2; 102), a plurality of shear valve fitting holes that is open on an axial end face of the tubular member in an axial direction of the tubular member , and extend in the axial direction, a plurality of liquid charging passages that communicate with the plurality of shear valve fitting holes , that extend in a radial direction of the tubular member from the plurality of shear valve fitting holes to an outer peripheral face of the tubular member , and that open on the outer peripheral face of the tubular member , a plurality of expansion chamber communication passages that provides communication between the shear valve fitting hole and the fluid pressure expansion chamber, and a plurality of shear valves (6; 106) each of which has a tube (27; 127), one end portion of which communicates with the expansion chamber communication passage and the other end portion (85; 185) of which is sealed, the tube (27; 127) projecting outward in the axial direction from the axial end face of the tubular member , and the plurality of shear valves (6; 106) being fitted in the plurality of shear valve fitting holes , and the shaft member (2; 102) has a tube shearing portion (84; 184) that is located on a circle, which extends along a circumferential direction of the shaft member and on which the other end portion of the tube is located, the tube shearing portion being overlapped with the other end portion of the tube in the circumferential direction of the shaft member, so as to interfere with the other axial end portion (85; 185) of the tube (27; 127) due to their relative movement, when a load equal to or higher than a prescribed value is applied to the tubular member or the shaft member. a shaft member (2; 102); and a tubular member rotatably fitted on the shaft member (2; 102), wherein the tubular member has a fluid pressure expansion chamber for pressing an inner peripheral face of the tubular member against an outer peripheral face of the shaft member (2; 102), a plurality of shear valve fitting holes that is open on an axial end face of the tubular member in an axial direction of the tubular member , and extend in the axial direction, a plurality of liquid charging passages that communicate with the plurality of shear valve fitting holes , that extend in a radial direction of the tubular member from the plurality of shear valve fitting holes to an outer peripheral face of the tubular member , and that open on the outer peripheral face of the tubular member , a plurality of expansion chamber communication passages that provides communication between the shear valve fitting hole and the fluid pressure expansion chamber, and a plurality of shear valves (6; 106) each of which has a tube (27; 127), one end portion of which communicates with the expansion chamber communication passage and the other end portion (85; 185) of which is sealed, the tube (27; 127) projecting outward in the axial direction from the axial end face of the tubular member , and the plurality of shear valves (6; 106) being fitted in the plurality of shear valve fitting holes , and the shaft member (2; 102) has a tube shearing portion (84; 184) that is located on a circle, which extends along a circumferential direction of the shaft member and on which the other end portion of the tube is located, the tube shearing portion being overlapped with the other end portion of the tube in the circumferential direction of the shaft member, so as to interfere with the other axial end portion (85; 185) of the tube (27; 127) due to their relative movement, when a load equal to or higher than a prescribed value is applied to the tubular member or the shaft member. <EOS>
