PURPOSE:To improve the linearity of the operation of a movable body, by linking freely flexible parallelogrammic frame bodies consisting of elastic surfaces and rigid surfaces and thus forming supporting members. CONSTITUTION:The rigid surfaces 16 of the supporting members 11 and 12 are coupled with coupling projection parts 9 and 10 of a holding member 8 and the rigid surfaces 19 are fixed to an external case 21 to support the holding member 8 movably in the external case 21. In this case, projections 9a and 10a are provided at the top of the coupling projections 9 and 10 and holes 16a are formed in the rigid surfaces 16 of the supporting members 11 and 12; and both members are fixed while the projections 9a and 10a are fitted in the holes 16a to specify the attachment angles of the supporting members accurately by the engagement between the projections 9a and 10a, and holes 16a. |
