A reciprocating mechanism for a fishing reel includes a first rotating body that rotates around a first axis extending in a direction perpendicular to a spool shaft, a second rotating body that rotates around a second axis disposed at a distance from the first rotating body in the spool shaft direction, and parallel to the first axis, a rotation transmission body bridged between the first rotating body and the second rotating body, and configured to circulate when a handle is rotated, and a movable body having a part engaging the rotation transmission body, the movable body reciprocating in the spool shaft direction together with the spool shaft, when the rotation transmission body is circulated, and when viewed from a direction along the first axis, a virtual straight line that connects the first axis and the second axis is inclined with respect to an axis of the spool shaft.
