The charging roller has a base layer formed of an electroconductive rubber composition containing (a) a polar rubber having an unsaturated bond or an ether bond, (b) an ion carrier containing one or more phosphonium salts selected from the group consisting of phosphonium salts having the formulae (1) and (2), and (c) a cross-linker, wherein the amount of (b) component ranges from 0.1 to 10 parts by mass per 100 parts by mass of the (a) component. The formula (1) represents [(H9O4)3(CnH2n+1)P]+(CF3SO2)2N—, and the formula (2) represents [(H9O4)3(CnH2n+1)P]+(CF3SO3)—.
摘要:
In an exhaust pipe connecting structure of a muffler, a through-hole 11a that penetrates one side wall portion of an outer shell 11 has a diameter larger than an outer diameter of an inlet pipe 2. The inlet pipe 2 is fixed at its portion corresponding to the through-hole 11a with a reinforcement-spacer member 3 having a cylindrical portion 31 that is gas-tightly connected with an outer circumferential surface of a projecting portion of the inlet pipe 2 and a flange portion 32 that projects outwardly from a through-hole side edge portion of the cylindrical portion 31. The flange portion 32 of the reinforcement-spacer member 3 is fixed by welding on an outer surface of the outer shell 11 all around the through-hole 11a. The cylindrical portion 31 of the reinforcement-spacer member 3 is fixed by welding on an outer circumferential surface of the inlet pipe 2 all around thereof. A stay 4 is provided with an insertion hole 41 coaxial with the cylindrical portion 31 of the reinforcement-spacer member 3 in a hollow part of the muffler main body, flange portions 43 at both end portion of a basal plate portion 42 of the stay 4 is fixed by welding on an inner surface of the outer shell 11. An end portion of the inlet pipe 2 is supported in a state where the end portion thereof is inserted in the insertion hole 41 of the stay 4.
