PURPOSE:To achieve reduction both in the manufacturing cost and in restriction of place where a core member is used, and at the same time, to make it possible to change a wrapper easily and speedily, by providing an engaging groove in which an edge portion of the wrapper formed along the inner lateral surface of the core member is inserted, and a projecting member placed in a ladder-like manner along the inner wall of the engaging groove ion an elongated direction for depressing the wrapper. CONSTITUTION:A core member 20 of an armrest 50 depresses a left edge portion 11a of a wrapper 10 while a projecting member 25 provided at a left partition wall 21a is inserted in an engaging groove 30, so that the left edge portion 11a is fixedly held between an inner wall of a left side surface 22a of the core member 20 and the projecting member 25. Accordingly, the left edge portion 11a can be securedly and positively held, even without being pressed by a pressing member such as a mounting member or a metal piece, etc. In the above arrangement, therefore, the wrapper 10 never slips off or displaces from the core member 20. As a result, restrictions on using places can be removed, and the wrapper 10 can be easily and speedily exchanged even in the case where the wrapper 10 is not torn out or scratched. |
