PROBLEM TO BE SOLVED: To provide a unidirectional intermittent feed unit with a unidirectional torque limiter incorporated in a ratchet wheel and its inner ring fixed to a housing, having improved feeding accuracy while keeping the rotating radius of the ratchet wheel constant by setting a range receiving radial force on the inner ring through the ratchet wheel to be constant. SOLUTION: A peripheral length L of a column portion 26 existing between a pair of specified adjacent pockets 8, 8 formed in the inner ring 3 is set to be a size including the range receiving the radial force Fy on the inner ring 3 through the ratchet wheel 1.
