    • PROBLEM TO BE SOLVED: To provide a rubber composition for diaphragm attaining a reliable bonding between a diaphragm rubber and a metal only with an adhesive without using a primer which is conventionally understood as indispensable, while maintaining desired preferable rubber characteristics required by diaphragm, and consequently having possibility of reducing cost. SOLUTION: The rubber composition used for bonding with a metal member (20) comprises a hydrogenated nitrile rubber (HNBR) having a middle high to high acrylonitrile content of 31-42 wt.%, sulfur and an organic peroxide used as vulcanizing agents, and an ester plasticizer, wherein the peroxide used as the vulcanizing agent is an α,α'-bis(tert-butylperoxy)-diisopropylbenzene and the ester plasticizer is an adipic acid ester.

    • PROBLEM TO BE SOLVED: To obtain an actuator in which the contraction force of a piezoelectric film is exerted in a direction perpendicular to the direction of its expansion and contraction. SOLUTION: The actuator includes: elastic bodies placed opposite to each other with a predetermined distance in-between; and a moving member provided between the elastic bodies so that the elastic bodies can be expanded and contracted. At least either of the elastic bodies is a piezoelectric film whose peripheral area is supported on a support member so that its expansion and contraction area is sandwiched or encircled. The moving member is moved in the direction substantially perpendicular to the direction of expansion and contraction by the expansion or contraction caused when the piezoelectric film is energized or de-energized.
