1. In an eraser holder, a tubular handle, an eraser clamping member inserted in one end of the handle, said eraser clamping member being formed from a single strip of resilient metal bent upon itself into U-s'naped formation, with the legs of the U-shaped formation having their free ends bent inwardly upon themselves to form enf largements between Which an eraser is to be clamped, and means at the other end of the casing for advancing and retracting the clamping member.

2. In an eraser holder, a flat tubular handle open at both ends, eraser clamping means inserted in one end of the holder, enlargements on the clamping member formed by bending portions of the member upon themselves, a screw member associated with the clamping member and projecting through the other end of the casing, and means for engaging the screw to advance and retract the clamping member.

3. In an eraser holder, a flat tubular holder, eraser clamping means inserted in one end of the holder, enlargements on the clamping member formed by bending portions of the member upon themselves and toward each other for contacting the eraser element, a screw member carried by the clamping means and projecting through the holder, and means for engaging the screw to advance and retract the clamping member.
