A micrometer wherein two or more spindles are disposed on one and the same axis, a spindle in contact with a workpiece to be measured is made unrotatable and a thimble is reduced in diameter. This micrometer comprising a main body (1, 101), a first spindle (15) threadably coupled to the main body and integrally rotatably connected to the thimble (17) and a second spindle (46, 146) connected to the first spindle (15) through a connecting mechanism (70, 150), the connecting mechanism (70, 150) including a contact member (61, 161) and a bearing (53, 153) for transmitting only the axial movement of the first spindle (15) to the second spindle (46, 146).

Micrometer

The present invention relates to a micrometer constituted such that an anvil is supported on a frame by means of parallel leaf springs so that the displacement of said anvil may be magnified and transmitted by a sector gear to a pointer; and said leaf spring is urged toward the spindle by another spring.

Constant pressure measuring micrometer

Inner diameter micrometer

The present invention relates to a hole gauge for measuring the inner diameter of a hole, which gauge comprises an axially movable spindle; a pair of tapered surfaces movable together with said spindle; a pair of contact points radially movable with respect to said spindle, guided by said pair of tapered surfaces; and a support arm for said pair of contact points, the outer surfaces of said contact points and said support arm being movable in parallel radially of said spindle.
