Abstract
A working machine may include: a first blade; a second blade overlapping with the first blade in an up-down direction; and a holding unit configured to hold the first blade and the second blade overlapping each other in the up-down direction. The first blade may be configured to reciprocate in a direction perpendicular to the up-down direction with respect to the second blade. The first blade may include a first elongated hole having a longitudinal direction along the reciprocating direction. The second blade may include a second elongated hole having a longitudinal direction along the reciprocating direction. The holding unit may include: a holding part inserted in the first elongated hole of the first blade and the second elongated hole of the second blade; and an outer sleeve having a cylindrical shape and supported by the holding part such that the outer sleeve is rotatable around the holding part.
