Description of the Related Art Conventionally, in measuring a gap portion which is difficult to measure with a vernier caliper, as shown in FIGS. 5 and 6, the tip of a square rod-shaped main scale 51 is cut off into a taper shape to cut the square rod-shaped book. Guide grooves 52 are provided on both sides of the scale 51, and the guide grooves 5
Cursor 2 is slidably fitted into 2 and the cursor K
In this configuration, the front cursor 53 on the front side and the rear cursor 54 on the rear side are connected by a connecting member 55, in which a cursor protrusion 56 is formed to project forward from the front cursor 53, and the main scale is also formed. On the side surface of 51, a scale 57 for depth measurement or gap measurement is displayed. 58 is a handle. Therefore, in order to measure the width of the gap portion, the taper portion 59 of the main scale 51 is inserted through the gap portion, and the cursor K is moved backward along with the taper portion 59 to move the cursor to the edge portion of the gap portion C. The projecting piece 56 is held in contact. In this state, the observer reads the scale 57 of the main scale 51 indicated by the reference line 60 formed on the rear cursor 54 to measure the taper width in the gap portion C, that is, the gap width.
