<p>PURPOSE:To relax the accuracy of flatness in a fitting seat for a main chassis or a cylinder fitting stand by providing a projecting part, which has an almost point-shaped apex part, near a screw hole for the fitting of the cylinder fitting stand on a surface in the cylinder fitting stand loading side of the main chassis. CONSTITUTION:When a cylinder fitting stand 2 is fixed with a screw to a main chassis 3, projecting parts 10B-10D are provided near through holes 2B-2D or the screw hole. Accordingly, an abutting part between the cylinder fitting stand 2 and main chassis 3 mainly goes to be the apex part of the projecting parts 10B-10D. Since this apex part is almost point-shaped, three-point support is obtained with point-contact for the cylinder fitting stand 2 and main chassis 3. Then, even when the accuracy of the flatness is comparatively low, this flatness does not give any influence to the fitting condition and fitting position of the said cylinder fitting stand 2 to the main chassis 3 and the deformation of the cylinder fitting stand 2 can be prevented. Thus, even when the allowance range of the accuracy in parts such as the main chassis, etc., is extended at a certain degree, tape traveling can be stabilized.</p> |
