PROBLEM TO BE SOLVED: To provide a reversing mechanism capable of performing rotation output in forward and reverse directions at a simple structure having few components. SOLUTION: When a connection shaft section 6 is connected with an output member 2, a planetary bevel gear 4 is integrally rotated together around a fixed shaft 3 of an input member 1 and the output member 2 so that a clutch means for connecting and disconnecting the connection shaft section 6 with the output member 2 and a brake means for stopping a rotation of the connection shaft section 6 when connection of the connection shaft section 6 with the output member 2 is stopped by the clutch means are arranged by supporting the planetary bevel gear 4 on a rectangular shaft member 5 which is turnable around the same fixed shaft 3 of the input member 1 and output member 2 and combining the connection shaft section 6 internally fitted on the output member 2 with the rectangular shaft member 5 at a right angle, and the output member 2 is forwardly rotated. When the connection shaft section 6 is disconnected with the output member 2, rotary output in both forward and reverse directions can be derived by a simple structure having few components so that the output member 2 is reversed by rotating the planetary bevel gear 4 only around a shaft 5a of the rectangular shaft member 5.
