PROBLEM TO BE SOLVED: To provide a shovel capable of securing braking of an output shaft regardless of the movement of a carrier member.SOLUTION: A shovel comprises a driving source for driving a turning body, a case, a reduction gear having a carrier member journaled to the case and supporting a gear for meshing with an output shaft of the driving source and a brake device having a brake disc of engaging with a spline formed in the case and the carrier member, and when setting the direction of turning to the driving source from the carrier member upward, in an upper part of the carrier member, assuming a minimum clearance dimension of a minimum clearance as C among clearances formed between the carrier member and the case and a distance up to a lower end part of the brake disc and the spline when stopping turning of the turning body as D, it is constituted so as to become D≥C. |
