摘要： This blind rivet makes it possible to obtain high water tightness and sufficient sealing properties for single blind rivets. This blind rivet (1) is for fastening to a base body having an opening and is provided with: a rivet main body (10) which comprises a large-diameter flange (16), a taper (15) adjacent to the flange, and a sleeve extending in the axial direction from the taper, and which has a bottomed hole (18) formed from the surface of the flange to the bottom of the sleeve; and a mandrel (30) which comprises a head (31) and a slender shaft having an external diameter smaller than that of the head and extending from the head. The head of the mandrel is arranged at the bottom of the bottomed hole in the rivet main body, and the shaft is combined so as to come out from the top surface of the flange of the rivet main body. In the sleeve of the rivet main body, a thick section (13) is formed which holds the head so said head cannot be removed from the bottomed hole in the rivet main body. The mandrel is pulled out and the sleeve is expanded in diameter, sealing the base body between the flange and the section with the expanded diameter.

摘要： A peel type blind rivet is presented which enables stable fastening with no fastening defects. The blind rivet is provided with a rivet body (10) which has a sleeve (11) and a flange (12) on one end of the sleeve, and a mandrel (20) which has a long, narrow shaft (21), a mandrel head (23) on one end of the shaft and a cutting edge portion (22) for cutting open the sleeve. The sleeve of the rivet body has a thick portion (15) which is contiguous to the flange, and a thin portion (14) is placed on the side of the sleeve end which has an inner diameter larger than the thick portion. The shaft of the mandrel has a large diameter portion (31) which is contiguous to the cutting edge portion, a middle diameter portion (33) having an outer diameter smaller than the large diameter portion, a small diameter portion (35) having an outer diameter smaller than the middle diameter portion 33, and a securing and attaching groove (34) which is between the middle diameter portion and the small diameter portion. When the blind rivet is fastened, the middle diameter portion of the mandrel causes the material of the thick portion to undergo metal flow and to flow into the securing and attaching groove, enabling the mandrel to be tightly secured to the rivet body.

摘要： Provided is a fastening structure including a blind rivet and capable of fastening, with stable fastening force, members to be mounted. A fastening structure is provided with a blind rivet and a nut (30). The blind rivet (1) includes: a rivet body (10) having a hollow sleeve (11) and a rivet head (12) and having a through-hole (14) formed therein; and a mandrel (20) having an elongated shaft (21) and a mandrel head (23). The mandrel head is disposed adjacent to the sleeve side end of the rivet body, and the mandrel shaft passes through the through-hole in the rivet body and protrudes from the rivet head-side end of the rivet body. The nut is disposed on the outer periphery of the sleeve side end of the sleeve of the rivet body and on the outer periphery of the mandrel head. An end of the sleeve is expanded in diameter by the mandrel head, the end having the expanded diameter engages with the female thread (32) of the nut, and members (41, 42) to be mounted are fastened between the nut and the rivet head.

摘要： A swaged collar and a swaged nut that buckle in a fixed axisymmetric shape when a thin-walled portion at the tip end is buckled and attached to a resin part. The swaged collar (10) is equipped with: a sleeve, having a thick-walled section (12), which is thick, a thin-walled section (14), which is thin, and a step section (15) between the thick-walled section and the thin-walled section; and a flange (11), which is formed on the thick-walled-section side of the sleeve, and has a larger diameter than that of the sleeve. A through-hole (13) is formed penetrating the sleeve and the flange, the sleeve is inserted into an attachment hole (33) of a resin component (30), and then the thin-walled part is buckled to form a buckled part (14a), thereby sandwiching and attaching the resin component (30) between the flange and the buckled part. When the outer diameter of the thin-walled portion is D, the wall thickness is t, the length is L, and the Poisson ratio is γ, the following equations are satisfied: r = D − t / 2 m = L π 4 r 2 t 2 20 12 1 − γ 2 1.2 m 1.8
