<p>PURPOSE:To provide a highly reliable loader having high productivity because of easy adjustment of the height of a vertical post and without occurrence of a secular change of the height of the vertical post. CONSTITUTION:A guide piece 23 for preventing the vertical post 4 from sliding in the direction of its axial line is provided, and also an energizing member 27 for energizing the vertical post 4 in the direction of the axial line of the vertical post 4 is provided in a leading guide 3 supporting the vertical post 23. Then, the vertical post 4 is provided with an engaging part 28, and the engaging part 28 is engaged by a stopper plate 29 fitted to the leading guide 3 in order to prevent the separation of the leading guide 3 from a chassis 1. Then, the energizing member 27 is arranged in a position where the direction of energizing the leading guide 3 of the energizing member 27 is almost offset against the direction of reaction force of the chassis 1 of a contact part 11 where the chassis 1 and the leading guide 3 are brought into contact with each other.</p> |
