To reduce volume of waste fluorescent tubes and to enhance a recycling efficiency by recovering non-glass parts of the waste fluorescent tubes without crushing.

This crusher is provided with a rotation drive apparatus 14; a rotary shaft 15; a glass crushing means 12 consisting of glass crushing plates PL, pivoted on the rotary shaft 15, in which multiple thin plates 16 disposed in the circumferential direction of the rotary shaft 15 with given spaces, are juxtaposed in the axial direction of the shaft 15 with given spaces so that the thickness direction is in the axial direction of the shaft 15, the thin plates 16 being independently turnable; and a crushing part 3 having an introduction port 11 for the waste fluorescent tubes to the glass crushing means 12 and a discharge port 13 for the waste fluorescent tubes from the glass crushing means 12. Spaces S1, S2 are formed allowing passing through of the non-glass parts between the periphery of the thin plates 16 and the discharge port 13.
