Patent attributes
The fastening member removing force measuring device according to the present invention includes a holding unit (300) for holding and pressing a fabric (953) around a snap member (921), a restricting unit for restricting the snap member (921), and a tensile force measuring unit for pulling the restricting unit away from the fabric (953) and measuring a tensile force. The holding unit (300) includes a die (420) for mounting thereon the fabric 953, and a fabric presser unit (500) for holding the fabric (953) placed on the die (420) together with the die (420). The die (420) includes a frame holding section (430) having an open face opposite to the fabric presser unit (500) and also having an accommodating section (434) inside thereof, a viscoelastic section (440) provided inside the accommodating section (434), and an elastic section (450) laminated on the viscoelastic section (440) in the accommodating section (434) on the side of the fabric presser unit (500) and formed with an elastic member harder than the viscoelastic member (440).
