Abstract

An applicator ( 1 ) includes a main body ( 10 ), a parallel crank ( 40 ), and a lever ( 50 ). The parallel crank ( 40 ) includes a first crank bar ( 41 ) and a second crank bar ( 42 ). The first crank bar ( 41 ) and the second crank bar ( 42 ) each have one end portion swingably coupled to the main body ( 10 ). To the lever ( 50 ), another end portion of the first crank bar ( 41 ) and another end portion of the second crank bar ( 42 ) are each swingably coupled. The second crank bar ( 42 ) covers at least a part of side surfaces on both sides of the first crank bar ( 41 ) in an axial direction of a pin ( 43 ) as a rotation axis of the first crank bar ( 41 ) with respect to the main body ( 10 ) in a sandwiching manner.

First claim

The invention claimed is:

1. An applicator comprising:
a main body;
a parallel crank that includes a first crank bar and a second crank bar, the first crank bar and the second crank bar each having one end portion swingably coupled to the main body; and
a lever to which another end portion of the first crank bar and another end portion of the second crank bar are each swingably coupled, wherein
the second crank bar covers at least a part of side surfaces on both sides of the first crank bar in a rotation axis direction of the first crank bar with respect to the main body in a sandwiching manner.

2. The applicator according to claim 1 , wherein
the second crank bar covers the side surfaces on both the sides of the first crank bar at least from the main body to the lever.

3. The applicator according to claim 1 , wherein
a shape on a cross section perpendicular to a longitudinal direction of the second crank bar is an approximately U shape.

4. The applicator according to claim 1 , wherein
the main body holds an extrusion rod coupled to the parallel crank, and
the first crank bar includes a cantilever that transmits a force to the extrusion rod.

5. The applicator according to claim 1 , wherein
the second crank bar is formed of a resin.
