<P>PROBLEM TO BE SOLVED: To provide a crane for realizing stable support and the quick replacement of a slide arm sliding means. <P>SOLUTION: The sliding means 2 is attained by providing a separate spring element 4 projecting by going over a sliding surface of the means. The sliding means is always pressed down by an opposed surface opposed to the sliding surface by the spring element projecting by going over the sliding surface of the sliding means, to thereby prevent falling-off from a holding frame formed extremely low. The spring element is formed as a plate spring, particularly in a simple and stable performance state. <P>COPYRIGHT: (C)2005,JPO&NCIPI |
