Abstract
In a holding frame, a frame forming portion includes a first holding surface and the second holding surface extending in different directions crossing an area surface of an inner area defined by the frame forming portion. In a state where a holder is magnetically attached to the frame forming portion, the first holding surface and the second holding surface respectively face inner surfaces of a first holding portion and a second holding portion of the holder. The first holding surface includes a first portion connected to a first connecting portion, and a first end located opposite from the first portion. The second holding surface includes a second portion connected to the first connecting portion, and a second end located opposite from the second portion. A distance between the first end and the second end is greater than a distance between the first portion and the second portion.
