There is provided a mechanism for effectively converting rotary motion to a wide range of swing motion. A mechanism 1 for converting rotary to swing motion includes a rotary shaft 2, a pivot shaft 3 and a swing element 4. The rotary shaft 2 has an upright section 2 A connected to a motor and a slant section 2 C extending at an angle to the upright section 2 A. The swing element is mounted to the pivot shaft 3. The slant section 2 C is positioned between a pair of confronting surfaces 4 D, 4 E of the swing element 4. The slant section 2 C is moved on and along the confronting surfaces during rotation of the rotary shaft 2 to cause the swing element 4 to be pivoted from side to side. This movement of the swing element 4 results in pivotal movement of the pivot shaft.
