Beschreibung
Zusammenfassung:	A torque detecting apparatus includes an annular magnetic flux collecting ring, a magnetic flux collecting holder surrounding and holding the magnetic flux collecting ring, and a magnetic shield including a circumferential end and attached to the outer periphery of the magnetic flux collecting holder. The magnetic flux collecting holder includes a housing portion that houses in its inner space the circumferential end of the magnetic shield. The housing portion includes an outer wall radially inwardly facing an outer peripheral surface of the circumferential end of the magnetic shield such that a first clearance is provided between the housing portion and the outer peripheral surface of the circumferential end of the magnetic shield.
