Claim 0:
1. A room-temperature-curable composition comprising:
(a) 100 parts by weight of a linear polyoxyalkylene compound having a number average molecular weight of 200 to 50,000 is represented by the following structural formula (2):, , wherein R1 may be the same or different, and each represents an alkyl group having 1 to 20 carbon atoms, in which an alkyl group having 3 or more carbon atoms may be a cyclic cycloalkyl group, an aryl group having 6 to 20 carbon atoms, an aralkyl group having 7 to 20 carbon atoms, a hydrogen atom, or a triorganosiloxy group represented by (R3)3Si—O— wherein each R3 is the same or different, and denotes a monovalent hydrocarbon group having 1 to 20 carbon atoms, n represents an integer of 2 to 8, m represents an integer of 2 to 8, Z is represented by the following formula (4):, , wherein R4 represents a divalent hydrocarbon group, p represents an integer of 2 or more, and the broken line represents a linking bond;
(b) 0.1 to 30 parts by weight of:
a hydrolyzable organosilicon compound having two alkoxysilyl-vinylene groups on the same silicon atom, represented by the following general formula (7):, wherein R5 independently represents an unsubstituted or substituted monovalent hydrocarbon group having 1 to 20 carbon atoms, R6 represents an unsubstituted or substituted alkyl group having 1 to 20 carbon atoms, or an unsubstituted or substituted cycloalkyl group having 3 to 20 carbon atoms, and a represents an integer of 1 to 3;
(c) 0.01 to 20 parts by weight of a curing catalyst;
per 100 parts by weight of the component (a),

(d) 3 to 1,000 parts by weight of a filler; and/or
(e) 0.1 to 30 parts by weight of an adhesion promoter; and
(f) 0.1 to 100 parts by weight of an organopolysiloxane represented by the following general formula (8):, , wherein R7 independently represents an unsubstituted or substituted monovalent hydrocarbon group free of an aliphatic unsaturated bond having 1 to 20 carbon atoms, and q represents such a numerical value that the organopolysiloxane has viscosity of 1.5 to 1,000,000 mPa·s at 23° C.
