Abstract
Lift of the rotation fulcrum of the armature is prevented. In the print head in which a print wire is furnished at an end portion, and that has an armature that is furnished rotatably, a yoke touches a rotation fulcrum of the armature; an elasticity member of a cantilever structure presses the rotation fulcrum of the armature to the yoke by sandwiching the armature between the yoke and the elasticity member; a housing fixes an end portion of the elasticity member and covers the elasticity member through forming a gap between the elasticity member and the housing; and a pressing member is arranged between the housing and the elasticity member and touches the housing and the elasticity member.

A print head in which a print wire is furnished at an end portion, and that has an armature that is furnished rotatably, comprising:
- a yoke that touches a rotation fulcrum of the armature;
- an elasticity member of a cantilever structure that presses the rotation fulcrum of the armature to the yoke by sandwiching the armature between the yoke and the elasticity member;
- a housing that fixes an end portion of the elasticity member and that covers the elasticity member through forming a gap between the elasticity member and the housing;
- and
- a pressing member that is arranged between the housing and the elasticity member and that touches the housing and the elasticity member.
