1. A reciprocating cutting blade apparatus comprising:
a pair of reciprocating cutting blades, each of the pair of reciprocating cutting blades extending longitudinally in a direction parallel to an X direction of a Cartesian coordinate system and having teeth extending in a Y direction, and each of the pair of reciprocating cutting blades disposed to overlap one another in a thickness direction parallel to a Z-axis of the Cartesian coordinate system;
a first support member and a second support member spaced apart from each other by a distance and configured to sandwich and reciprocably support the pair of reciprocating cutting blades; and
a transmission case to which the first support member and the second support member maintaining the distance therebetween are mounted,
the transmission case including:
a grease inlet and a first grease reservoir provided on first side of the first support member, the first grease reservoir being configured to accumulate grease poured from the grease inlet and;
a second grease reservoir provided on a second side of the second support member and configured to accumulate the grease poured from the grease inlet,
the first support member including a through-hole configured to communicate with the first grease reservoir,
the second support member including a through-hole configured to communicate with the second grease reservoir, and
the pair of reciprocating cutting blades including through-holes configured to allow communication between the through-hole of the first support member and the through-hole of the second support member, respectively.
