Claim:
A drag control member attachment structure comprising: a first cam member including a drag control member attachment part; a second cam member configured to engage with the first cam member and move in a pivot axis direction in response to pivoting of the first cam member; a guiding portion including a hexagonal section having first through sixth outer peripheral surfaces that non-rotatably and movably guide the second cam member in the pivot axis direction; a guide fastening portion including a hexagonal recessed section that receives the hexagonal section of the guiding portion; and a pivot support portion disposed on an outer periphery side of the guide fastening portion, the hexagonal section including first and fourth inner peripheral surfaces spaced at intervals from the first outer peripheral surface and the fourth outer peripheral surface opposing the first outer peripheral surface, respectively, a second inner peripheral surface having a first contact part configured and arranged to be in contact with a first part on a side of the second outer peripheral surface adjacent to the first outer peripheral surface, and a first separated part disposed on a second part of a side adjacent to the second outer peripheral surface and spaced at an interval away from the second outer peripheral surface, third and sixth inner peripheral surfaces configured and arranged to be in contact with the third outer peripheral surface and the sixth outer peripheral surface opposing the third outer peripheral surface, and a fifth inner peripheral surface having a second contact part configured and arranged to be in contact with a third part on a side of the fifth outer peripheral surface adjacent to the fourth outer peripheral surface, and a second separated part disposed on a fourth part of a side adjacent to the fifth outer peripheral surface and spaced at an interval away from the fifth outer peripheral surface, the first through sixth inner peripheral surfaces being arranged along a pivoting direction.
