<P>PROBLEM TO BE SOLVED: To improve maintainability by taking out a wiper driving unit still in an assembly state, in a wiper driving device of a construction machine having an obstacle for limiting retreat of the wiper driving unit, in the rear of the wiper driving unit. <P>SOLUTION: This wiper driving device includes the wiper driving unit 3 arranged in the rear of a windshield 5, a hole 2 penetratingly formed in the windshield 5, a wiper pivot shaft 6 extended in front of the windshield 5 by being inserted into the hole 2 from the wiper driving unit 3, and the obstacle 7 (a steering column cover 71) arranged in the rear of the wiper driving unit 3 and limiting the retreat of the wiper driving unit 3. The hole 2 is constituted of a long hole 2 formed long along the direction for separating from the obstacle 7. Since the wiper driving unit 3 separates from the obstacle 7 by moving the wiper pivot shaft 6 along the long hole 2, the wiper driving unit 3 is retreated and taken out still in the assembly state. <P>COPYRIGHT: (C)2013,JPO&INPIT |
