ABSTRACT:
A micrometer head adapted to be mounted to a measuring instrument or the like and used for measuring and precision feeding includes an adjusting ring (23) spaced a predetermined distance apart from a thimble (6). This adjusting ring (23) is connected to an intermediate tubular member (16) which is provided on a sleeve (15) coupled onto a spindle (1) in a manner so as to be rotatable relative to the sleeve (15). A coil spring (35) is confined between the adjusting ring (23) and a graduation ring (17) disposed inside the thimble (6). Rotation of the adjusting ring (23) causes the spindle (1), sleeve (15), graduation ring (17) and thimble (6) to be simultaneously moved relative to a mount fixable portion (31) adapted to be mounted to the measuring instrument or the like.
