A measurement device according to one embodiment of the present disclosure is a measurement device that measures a position of an annual part to be measured that is arranged at an opening edge of a hole formed in a member to be measured, and the measurement device includes: a probe that is displaceable in an axial direction; a holder that holds the probe; and a measurement instrument that measures displacement of the probe in the axial direction. The probe includes an inclined portion at an tip end of the probe, the inclined portion being inclined relative to a central axis of the probe at an angle equal to an angle defined between a central axis of the hole in the member to be measured and a horizontal plane in a state in which the member to be measured is mounted on the horizontal plane.

A linear gage includes a spindle, a guide cylinder surrounding a portion of the spindle and configured to guide the spindle to move forward and rearward in an axis line direction, and a guide slit portion having a guide slit extending parallel to the axis line of the guide cylinder, with a gap provided between the guide slit and an outer surface of the guide cylinder. An attitude adjustment pin extends into the guide slit and is fixed to a side surface of the spindle. The attitude adjustment pin is an eccentric pin.

A measuring instrument includes a main body casing, a detector on the main body casing and detecting an amount of stylus head displacement, a display on an outer surface of the casing; a plurality of key switches on the outer surface, a menu proximate the display on the outer surface, and a display controller controlling the display. The display includes a main display and a cursor display, which is arranged in a location alongside the menu and displays a cursor pointing to the menu, and performs control such that a measured value based on an amount of displacement is displayed, but the cursor is not displayed when in a measurement mode where the detector detects the amount of displacement, and such that a cursor is displayed so as to point to the menu corresponding to a selected menu when in a settings mode where measurement conditions are set.

Applicant has disclosed a chamfer gage with interchangeable anvil assemblies which can measure the diameter of chamfered holes and the chamfer angle (up to 135°). In the preferred embodiment, the chamfer gage comprises: an indicator housing; a compression fitting, attached to the housing, for securing an indicator spindle for movement inside the housing; and an interchangeable anvil assembly, having an anvil body with a depressible anvil or plunger inside, which can be detachably connected to the indicator housing by a threaded thumb ring rotatably mounted on the housing. Another interchangeable anvil assembly can be swapped within thirty seconds to measure the chamfer of a different hole size.

Provided is a misalignment determining device having a size thereof in an axial direction being made short. The misalignment determining device includes a case, a dial gauge, a holder portion, a support portion, a pivotal portion, a lever member, and a slide member. The slide member is placed in contact with a stylus of the dial gauge. While the pivotal portion and the lever member are rotated in synchronism with rotation of the holder portion, a pivot amount of the pivotal portion is transmitted to the slide member via the lever member, and based on an amount of movement of the slide member along an axis direction, the dial gauge determines the pivot amount.

A mechanical gauge includes a stock panel with a first measurement scale, and a slide movably arranged relative to the stock panel. The first measurement scale has a series of marks spaced apart at regular intervals within a region of interest. The slide includes a second measurement scale adapted to selectively overlie the first measurement scale within the region of interest. The second measurement scale has a second series of marks spaced apart at regular intervals corresponding to the first series of marks of the first measurement scale. An elongated measurement probe is affixed to the slide and adapted for selectively extending into a groove formed in the tread of the vehicle tire.

An adjustable support holder for a gauge device on a magnetic base to provide adaptable positioning and mounting for measuring instruments. The support holder comprises of a gauge engagement platform rotatable with a support base adapted to be mounted on an electro-magnetic attachment for selectively securing on a magnetically attractive surface. An integrated remote locking assembly will selectively release and lock the rotatable platform and attached measuring gauge allowing for 360-degree rotation and orientation there therewith.
