1. An aircraft reaction link connected to an actuator whose first end side is pivotably attached to a moving surface of an aircraft or to a member attached to the moving surface, the aircraft reaction link comprising: a link body portion that has a pair of leg portions extending linearly and arranged side by side and a connecting portion connecting one end portion of each of the leg portions to each other, the pair of leg portions and the connecting portion being made of fiber reinforced plastic and formed integrally, and the other end portion of each of the leg portions being provided pivotably with respect to a second end side of the actuator; anda head portion that has a plurality of head constituent members fixed to the connecting portion in a state of being arranged such that the plurality of head constituent members surrounds a whole circumference of the connecting portion, at least partially in a longitudinal direction of the connecting portion and such that the connecting portion is sandwiched by the head constituent members, and that is provided pivotably with respect to the moving surface, via a bearing provided in one of the head constituent members. 2. The aircraft reaction link according to claim 1, further comprising: a cord body that is wound around the head constituent members so as to surround the head constituent members, and thus presses the head constituent members toward the connecting portion side and fixes the head constituent members to the connecting portion. 3. The aircraft reaction link according to claim 2, further comprising: a head fixing portion made of fiber reinforced plastic that contains reinforced fibers serving as the cord body and is provided so as to surround the head constituent members. 4. The aircraft reaction link according to claim 2, wherein the head constituent members include a first head member and a second head member, andthe first head member and the second head member each have a pressing portion that is pressed toward the other head member such that the pressing portions of the first and second head members sandwich and retain the connecting portion. 5. The aircraft reaction link according to claim 4, further comprising: a wedge member that is formed in a wedge shape whose thickness becomes thinner from a first end side toward a second end side, and that is driven between the connecting portion and the first head member or the second head member such that a first surface of the wedge member comes into contact with the first head member or the second head member, and such that a second surface of the wedge member that is opposite to the first surface comes into contact with the connecting portion. 6. The aircraft reaction link according to claim 5, wherein the wedge member is driven between the pressing portion and the connecting portion. 7. The aircraft reaction link according to claim 5, further comprising: a pair of the wedge members that are driven in directions in which the wedge members approach each other, between the connecting portion and the first head member or the second head member; anda connecting member that connects the wedge members to each other. 8. The aircraft reaction link according to claim 5, wherein at least one of the first head member and the second head member has a wedge recess portion that forms a gap into which the wedge member is driven, between the wedge recess portion and the connecting portion, in a state where the head portion is fixed to the connecting portion. 9. The aircraft reaction link according to claim 8, wherein the wedge recess portion has a bottom portion having a flat surface that forms the gap into which the wedge member is driven, between the flat surface and the connecting portion, andthe first surface of the wedge member or the second surface of the wedge member is in contact with the flat surface. 10. The aircraft reaction link according to claim 1, wherein the fiber reinforced plastic contained in the leg portions includes:a first material in which a direction of fibers contained therein is arranged so as to extend in an extending direction of the link body portion; anda second material in which directions of fibers contained therein are arranged so as to perpendicularly intersect each other and intersect the direction of the fibers contained in the first material. 11. The aircraft reaction link according to claim 10, wherein the connecting portion has:a linear portion that extends in a direction intersecting the pair of leg portions; anda pair of bent portions each connecting one of the pair of leg portions to one end portion of the linear portion and connecting the other of the pair of leg portions to the other end portion of the linear portion, andthe bent portions each have the first material, the second material, and a third material in which a direction of fibers contained therein are arranged in a direction perpendicular to the direction of the fibers contained in the first material. 12. The aircraft reaction link according to claim 1, further comprising: a bearing portion that is provided in the other end portion of each of the pair of leg portions, and that is fixed to the other end portion by a fastening member extending in a direction perpendicular to an extending direction of the leg portions,wherein the fastening member fixes the bearing portion to the other end portion, as a result of being inserted in both a first through hole formed in the other end portion and a second through hole formed in the bearing portion, andthe aircraft reaction link further comprises a spacer that is inserted in a gap formed in the extending direction of the leg portions between the other end portion and the bearing portion. 13. The aircraft reaction link according to claim 12, wherein a projecting portion projecting from the other end portion of each of the pair of leg portions is formed in the other end portion,the bearing portion has a pair of support portions that sandwich and retain the projecting portion, andthe fastening member is inserted in both the first through hole formed in the projecting portion and the second through hole formed in each of the pair of support portions. 14. The aircraft reaction link according to claim 12, wherein the bearing portion has:a bearing retaining portion fixed to the other end portion of each of the pair of leg portions; anda bearing body pressed into a through hole formed in the bearing retaining portion. 15. A moving surface drive unit comprising: an actuator whose one end side is pivotably attached to a moving surface of an aircraft or to a member attached to the moving surface; andthe aircraft reaction link according claim 1 that is connected to the actuator.
