摘要： An objective lens actuator includes a lens holder, a protector holder, and a protector. The lens holder in which the objective lens is provided has a face configured to oppose the disc. The protector holder is provided on the face of the lens holder. The protector is formed with an opening defined by a first inner face, a second inner face and a bottom face between the first inner face and the second inner face. The protector has a parallelepiped shape elongating in a first direction parallel to the disc. A part of the protector is inserted in the opening so as to contact the first inner face and the second inner face and to extend from the bottom face toward the disc. A first distance between an end of the protector in a second direction in which the protector extends toward the disc and the disc is shorter than a second distance between the objective lens and the disc. A gap is formed between an end of the opening and an end of the protector in the first direction.
