(54) Sliding pad for a jib


(57) An extendable and stowable jib (7) according to the present invention comprises a plurality of jib structures (71, 72 and 73) telescopically inserted into each other. A sliding pad (10) sliding on an inner surface (72i) of an outer jib structure (72) is attached to the base end portion of an inner jib structure (73). The inner jib structure (73) is provided with a supporting member (23) protruding towards the inner surface (72i) of the outer jib structure (72). The sliding pad (10) is connected to the supporting member (23) so as to restrict movement in the perpendicular direction to the protruding direction of the supporting member (23). The present invention can prevent from damaging the jib structure due to a screw and drop-off of the sliding pad. The present invention does not lower strength of the jib structure.
