Alternatively, the second direction may be the longitudinal direction of the structure in the X-axis direction.

The moving member 140 is slidably coupled to a guide member 115 extending in a second direction (ex. Y-axis direction) on one surface (ex. lower surface) of the first fixing member 110. When the first stepped surface 11 and the second stepped surface 12 relatively move in the second direction, the moving member 140 moves relative to the first fixing member 110 in the second direction.

A second through hole 141 through which the scale member 130 passes is formed in the moving member 140.

For example, the second through-hole 141 may be formed such that the inner surface of the second through-hole 141 is disposed close to the outer surface of the scale member 130.

Z-axis direction) through the second through hole 141, and the scale member crossing the edge of the second through hole 141 Since the scale of 130 is close to the edge of the second through hole 141, the operator can easily read the scale.

Alternatively, the second through hole 141 may be formed such that an inner surface of the second through hole 141 is in contact with an outer surface of the scale member 130. At this time, even when the step difference in the first direction of the structure changes, the scale member 130 should be able to slide relative to the inner surface of the second through hole 141 to perform relative movement in the first direction. In this case, since the scale of the scale member 130 crossing the edge of the second through hole 141 comes into contact with the edge of the second through hole 141, the operator can more easily read the scale.

According to this embodiment, the movable member 140 that penetrates and crosses the scale member 130 is coupled to the first fixing member 110 so as to be able to move relative to the second direction, so that the first stepped surface 11 Even if the and the second stepped surface 21 move relative to each other in the second direction, it is possible to accurately measure the stepped step.

When the first stepped surface 11 and the second stepped surface 12 relatively move in the second direction, the moving member 140 moves relative to the first fixing member 110 in the second direction.

A second through hole 141 through which the scale member 130 passes is formed in the moving member 140. In this embodiment, the second through hole 141 may be formed to be larger than the previous embodiment without the auxiliary moving member 150 in consideration of the relative motion of the auxiliary moving member 150 to be described later.

The auxiliary moving member 150 is slidably coupled to the auxiliary guide member 145 extending in a third direction on one surface (ex. lower surface) of the moving member 140. When the first stepped surface 11 and the second stepped surface 12 relatively move in the third direction, the auxiliary moving member 150 moves relative to the moving member 140 in the third direction.

A third through hole 151 through which the scale member 130 passes is formed in the auxiliary moving member 150.

For example, the third through hole 151 may be formed such that the inner surface of the third through hole 151 is disposed close to the outer surface of the scale member 130. In this case, the scale member 130 can easily move relative to the first direction through the third through hole 151, and the scale of the scale member 130 crossing the edge of the third through hole 151 is zero. 3 It is close to the edge of the through hole 151 so that the operator can easily read the scale.

Alternatively, the third through hole 151 may be formed such that the inner surface of the third through hole 151 is in contact with the outer surface of the scale member 130. At this time, even when the step difference in the first direction of the structure changes, the scale member 130 should be able to slide relative to the inner surface of the third through hole 151 and move relative to the first direction. In this case, since the scale of the scale member 130 crossing the edge of the third through hole 151 comes into contact with the edge of the third through hole 151, the operator can more easily read the scale.

The ring member 160 has a ring shape surrounding the scale member 130. The ring member 160 is disposed in the first through hole 111. For example, the ring member 160 may be disposed in the center of the first through hole 111.

The operator can measure the step by reading the scale of the scale member 130 intersecting the ring member 160.

The ring member 160 may be formed such that the inner surface of the ring member 160 is close to the outer surface of the scale member 130. In this case, the scale member 130 can easily move relative to the first direction (ex. Z-axis direction) through the ring member 160, and the scale of the scale member 130 crossing the ring member 160 is It is close to the ring member 160 so that the operator can easily read the scale.

The elastic member 170 provides an elastic force for returning the ring member 160 to an initial position in the first through hole 111. For example, it is assumed that the position of the ring member 160 shown in FIGS. 12 and 13 is an initial position.

The elastic member 170 may be a string made of an elastic material such as a rubber band.

The elastic member 170 is provided in plural, and the plurality of elastic members 170 elastically support the ring member 160 to the first fixing member 110. For example, the elastic member 170 elastically supports the ring member 160 on the inner surface of the first through hole 111.

When the first stepped surface 11 and the second stepped surface 21 move relative to each other in the second direction (ex. Y-axis direction) or the third direction (ex. X-axis direction), the ring member 160 penetrates through the ring member 160. The scale member 130 moves in the first through hole 111.

At this time, the ring member 160 that is elastically supported by the first fixing member 110 (ex. the inner side of the first through hole 111) by the elastic member 170 is formed while surrounding the scale member 130. 1 It can move in the first through hole 111 without leaving the through hole 111.

In this case, the operator may measure the level difference by reading the scale of the intersection area between the ring member 160 and the scale member 130 moving in the first through hole 111.

According to this embodiment, even if the first step surface 11 and the second step surface 21 move relative to each other in the second or third direction, the ring member 160 surrounding the scale member 130 is always 1 By being located in the through hole 111, even when the first stepped surface 11 and the second stepped surface 21 are moved relative to each other in the second or third direction, the operator can each time the first through hole 111 It is possible to accurately measure the step difference by reading the intersecting scale between the ring member 160 and the scale member 130 positioned inside.
