２ａより突出させる。The waterproof washer of the present invention will be described below with reference to the reference numerals in the accompanying drawings.
A metal washer body 1 in which a short cylindrical peripheral wall 2 is provided concentrically with the bolt insertion hole 3 in the central portion on the back side outer peripheral portion; and a central through hole 6 is communicated with the bolt insertion hole 3 to the washer body 1. The bush 4 made of rubber to be fitted into the bush 4 is provided with a spherical convex portion 12 centered on the central through hole 6.
Is provided on the back side of the peripheral wall 2, and the spherical convex portion 12 is projected from the back surface 2a of the peripheral wall 2.

する。The bolt 9 is inserted through the bolt insertion hole 3 of the washer body 1 and the central through hole 6 of the bush 4 into the bolt insertion hole 8 of the fixed object 7 and the bolt insertion hole 14 of the fixed object 13, and the bolt is inserted. When the nut 11 is screwed from the tip of the bolt 9 and the bolt 9 is tightened to a predetermined torque, the tightening force of the bolt 9 is applied to the rubber bush 4 via the head 10 of the bolt 9 and the washer body 1. . With this compression load,
The spherical convex portion 12 of the bush 4 in contact with the surface of the fixing target 7 is crushed and seals the bolt fitting hole 8 of the fixing target 7.

Is a metal bushing body 1 in which a rubber bush 4 is fitted by fitting the bolt insertion hole 3 of the washer body 1 and the central through hole 6 of the bushing 4 into communication.
The spherical convex portion 12 formed on the back side of the crushed portion is crushed by the tightening of the bolt 9 and seals the bolt fitting insertion hole 8 of the fixed object 7, so that sufficient waterproof performance is retained. Is completely unnecessary.

い。The spherical convex portion 12 of the bush 4 has a central through hole 6
Since the bolt insertion hole 3 of the washer body 1 that presses the front side of the bush 4 is provided in the central portion, the spherical convex portion 12 is pressed evenly around the central through hole 6. , There will be no unsealed parts.
