An eyeglass lens processing apparatus (1) for processing a periphery of a lens, includes: lens rotating means (100a) for rotating a pair of lens chuck shafts (102) that hold an eyeglass lens; processing tool rotating means (300, 420) for rotating a processing tool rotating shaft (161a, 400a) to which a processing tool (168, 400) for processing the periphery of the lens is mounted; moving means (100c) for moving about the lens chuck shafts or the processing tool rotating shaft as a moving shaft in an axis-to-axis direction in which an axis-to-axis distance between the lens chuck shafts and the processing tool rotating shaft is changed; a waterproof cover (61) provided with a first elongated hole (75L, 75R) through which the moving shaft is inserted, the waterproof cover configuring a processing chamber (60); and a shield unit (70) provided in the waterproof cover for preventing grinding water from leaking out of the first elongated hole, the shield unit being configured to be rotated in response to movement of the moving shaft. |
