PROBLEM TO BE SOLVED: To surely mount a flower-shaped lens hood on a conversion lens screwed to a camera lens. SOLUTION: A lens hood mounting structure forms a concave-convex face 12 on an outer peripheral face by protruding a flange part 11 on the edge part of the conversion lens 10 screwed to the front face of the camera lens. A slip stop tongue piece 24 having a pair of elasticities separated from an inner peripheral face 21 is protruded on the rear end of the flower-shaped lens hood 20 having the inner peripheral face 21 fitted loose to the outer peripheral part of the concave-convex face 12 to protrude a locking pawl 24a on the inner face of the free end. When the flower-shaped lens hood 20 is inserted in the front face of the conversion lens 10, the locking pawl 24a is slid on the outer peripheral part of the concave-convex face 12. The slip stop tongue piece 24 is widened to be inserted, in the insertion state, the locking pawl 24a is engaged with a flange part rear end face 11b to stop slipping, and a protrusion 22 is engaged with the concave part of the concave-convex face 12 to stop rotating.
