支持部材の載置台本体への連結位置を変更できる。According to the above construction, the lower holder is fitted on the lower surface side of the mounting table main body so as to be capable of being relatively displaced in the longitudinal direction via the concave portion and the convex portion, and being restricted in the relative displacement in the width direction. By screwing the screw member on the outside of the mounting table main body, the support member can be pressed and fixed to the mounting table main body. Thereby, without providing a difficult-to-clean groove in the mounting table main body as in the related art, and without increasing the width dimension of the mounting table main body more than required for mounting the subject,
The support member can be connected to the mounting table main body. Further, by loosening the screwing of the screw member, the connecting mechanism can be displaced in the longitudinal direction with respect to the mounting table main body, so that the connecting position of the support member to the mounting table main body can be changed.

らの変位を防止できる。The screw member is inserted into the upper holder and the supporting member, and a moment acting on the supporting member in the longitudinal direction of the mounting table main body acts on the lower holder by a force in the longitudinal direction of the mounting table main body. Then, the lower holder is pressed against the mounting table main body by the moment. Therefore, by loosening the screwing of the screw member, the coupling mechanism can be displaced in the longitudinal direction with respect to the mounting table main body,
The position at which the support member is connected to the mounting table main body can be changed, and the movement of the support member can be prevented even if the screw member is forgotten to be tightened. Therefore, displacement of the subject on the mounting table main body from a predetermined position can be prevented.
