Abstract
A caulking jig comprises a main body, a blade portion having a blade edge, a projection member fit in the main body, an urging member which urges the projection member, and an engagement mechanism configured to engage the projection member to the main body. In a state in which the projection member is not engaged, the projection member is held at a projected position where a distal end portion of the projection member is projected from the blade edge. In a state in which the projection member is engaged, the projection member is held at an entered position where the distal end portion is retracted to a more entered position than the blade edge.
