<P>PROBLEM TO BE SOLVED: To provide a turning post device capable of corresponding to a large compression load in the vertical direction and a load in the lateral direction, capable of corresponding to the eccentricity accompanied by the swing of a support and, further, capable of facilitating the replacement of a component. <P>SOLUTION: A turning flange 17b of a turning post 17 is mounted on a base flange 16b of a base post 16 so as to permit turning freely via a main bush 18 which receives a compression load, the support 20 is pivotally attached to an upper part of the turning post 17 via a connection pin 19, further, the support 20 is arranged by a spherical bush 21 disposed on the outer circumference of the connection pin 19 so as to permit turning freely with respect to a shaft line O of the base post 16, and a flange-receiving unit 22 which supports the base flange 16b and the turning flange 17b in the form of surrounding the base flange 16b and the turning flange 17b so as to receive a tensile load to the upper side acting on the support 20 via an outer surface bush 23 and, at the same time, receive a load in the direction perpendicular to the shaft line O of the base post 16 via an outer circumferential bush 24. <P>COPYRIGHT: (C)2013,JPO&INPIT |
