PURPOSE: A lower arm supporting apparatus is provided to prevent displacement of a lower arm even in a long time work by providing a uniform elastic force to a lower arm support. CONSTITUTION: A lower arm supporting apparatus(1) includes first and second mounting brackets, a lower arm support unit, a location restriction unit, and a load absorbing unit. The first and second mounting brackets(11,13) are mounted at a certain interval on a carriage, corresponding to the location of a lower arm. The lower arm support unit(20) is inserted between the mounting bracket to support the lower side of the lower arm. The location restriction unit(40) is installed on the inner side of each mounting bracket and supports the back of the lower arm support unit to restrict the lower arm supporting unit. The load absorbing unit(70) is mounted behind the first mounting bracket and connected to the lower side of the lower arm support unit in order to absorb the load which is applied by the lower arm to the lower arm support unit. |
