Abstract
A reciprocating blade apparatus includes a pair of reciprocating blades stacked on one another in a thickness direction, and a transmission case including a power train configured to reciprocate the pair of reciprocating blades. The power train includes a pair of eccentric cams, and a pair of reciprocating members including fitting holes in which the eccentric cams are fitted, respectively. The pair of reciprocating members is guided to be able to move along an axis line which is parallel to a moving direction of the pair of reciprocating blades and runs through a rotation axis of the eccentric cams.
