Abstract: A tensioner including a support member, a thrust member supported so as to be capable of reciprocating movement in a straight line along a first direction with respect to the support member, and a contact-type flat spiral spring. The flat spiral spring is disposed adjacent to the thrust member in a second direction orthogonal to the first direction. The flat spiral spring has a coil axis direction running in a third direction orthogonal to both the first direction and the second direction and includes an inner-end portion anchored to the support member and an outer-end portion anchored to the thrust member so as to bias the thrust member in a forward-direction and so as to be wound-up by movement of the thrust member in a retraction-direction.

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.

Abstract: Provided is a load measuring device and a load measuring method, capable of preventing a measuring error caused by an initial load in a state where an elastic member is held by a pair of holding parts when a load of the elastic member at the time of stretching is measured. A pair of holding parts 5, 7 are caused to approach or space away with respect to each other relatively to an initial position at which the pair of the holding parts hold a close contact spring S, thereby making an initial load measured at the initial position zero, the pair of holding parts 5, 7 are caused to space away with respect to each other from a starting position being a position at which the initial load becomes zero, and a load at a time of stretching is caused to be measured.
