PURPOSE: To attain smooth sliding movement of a structure when the structure is journaled with a slide type rubber journaling body by forming a plurality of continued grooves between the end parts of the surface of an ethylene tetrafluoride plate fixedly secured on the upper face of a rubber journaling body. ;CONSTITUTION: A plurality of air coming in and out grooves 3 for preventing f. sticking which are continuously extended from one end part to the other part are provided on the surface of an ethylene tetrafluoride plate 2 fixedly secured on a rubber journaling body 1 through an upper steel plate 5. l Next this is placed on a supporting structure such as abutment and fixed. Next an upper side slide journaling body fixedly secured on the underside of an upper structure such as bridge girder is slidably placed on the plate 2. Hereby, it can be prevented that the ethylene tetrafluoride plate is sucked to the upper side slide journaling plate so as to be hard to slide.;COPYRIGHT: (C)1995,JPO
