摘要： An object hardness measuring device includes a first side portion, a second side portion, a pedestal unit, a load unit, a measuring unit, and a holding unit. The load unit applies a load to the measurement object. The measuring unit is able to measure, in a state where the load acts on the measurement object, at least one of a movement distance of the second side portion with respect to the first side portion and a change amount of the load when the second side portion is moved either at a predetermined speed or to a predetermined position. The holding unit is able to hold the measurement object, and is movable between the first side portion and the second side portion by the slide rail unit.

The second protrusion has a second through hole. At least either the first through hole or the second through hole has an inclined edge that extends obliquely upward from a base of the thumb part or the index finger part on a peripheral edge forming the through hole. The first protrusion and the second protrusion are engaged with each other in a state where the first through hole and the second through hole are connected to each other in a chain shape.
