The present invention provides a holding structure of a vehicular movable member, which weakens a clamping fixing operation force for elastically clamping and fixing with one another through closing motion, and increases a pulling-out operation force for releasing the clamping fixing state. The gesture state of a table which is connected with the back surface part of a seat backrest with a reverserotation mode through the clamping fixing of a holding member and a linear component that is slidably connected with the table and the back surface part (base plate) of the seat backrest. The holdingmember is formed with a mode that the claw which is taken as the clamping fixing part of the linear member is elastically supported by a compression spring. The holding member is pressed as the closing motion of the linear member, is rest after backward pushing along with the flexible deformation of the pressing spring, and is clamped and fixed to the linear member. The compression spring is bentand deformed at the paw in being pressed as the closing motion of the linear member, and executes axial compression deformation in being pressed because of the pulling-out motion of the linear member.
