Abstract

PURPOSE:To enhance safety, and concurrently prevent both measured surfaces of plates, which are mutually reverse in slope, from being damaged by housing a gauge main body formed in an acute tri-angle shape within a case member in such a way as to be freely projected out/drawn back. CONSTITUTION:A case member 3 made of synthetic resin is so formed that a gauge main body 1 made of stainless steel can be housed therein wherein the gauge main body is formed into an acute tri-angle shape with it made out of a plate constant in thickness (for example around 5mm), and a projection hole 4 through which the gauge main body 1 is projected out/drawn back, is provided for the tip end of the case member. When it is in use, the gauge 1 is projected out of the projection hole 4 of the member 3 so as to be inserted between both the plates to be measured, both side surfaces of the gauge main body 1 are brought into contact with the plates, a graduation at that time is taken out, and as a result, the facing dimension of a clearance existing between the plates is thereby measured. In this case, both side surfaces of the plates, which are mutually reverse in slope, can be prevented from being damaged. When it is not in use, or carried by an operator, since the gauge main body 1 can be housed in the case member 3, it is still safe for the operator to put it in his chest pocket.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a taper gauge used for measuring, for example, a facing dimension of a gap existing between two members and an inner diameter of a small diameter pipe.

2. Description of the Related Art Conventionally, as a taper gauge of this type, as shown in Japanese Utility Model Laid-Open No. 4-64704, the surfaces of stainless steel plates having a substantially triangular shape, for example, a plate thickness of 1.2 mm and having a constant plate thickness are mutually attached. There is known a structure in which graduations indicating the distance between both side surfaces having opposite slopes are sequentially attached.

However, for example, a plate material is inserted into a gap between two members, both side surfaces of the plate member are brought into contact with the two members, and the scale at this time is read to read and measure the facing dimension of the gap existing between the two members. Alternatively, similarly to this, a plate material is inserted into the inner hole of the pipe to measure the inner diameter.

[0004]

However, in the case of the above-mentioned conventional structure, since the tip of the triangular plate member is sharply formed, when it is used, for example, it is stored in a chest pocket and carried. A very dangerous situation is predicted, and both sides of the plate that is the measurement surface, which have opposite slopes, may be damaged by collision with the member to be measured or other external members. have.
