A constant-pressure mechanism includes: a pressure transmission member (3A) being linearly movable in a predetermined direction and being urged by an urging member (1A); a rotary member being rotatable around a central shaft located in a case receiving the pressure transmission member; a follower member (4A) supported to the case (2A) so as to be movable linearly; and a displacement conversion mechanism (7A, 8A) interposed among the pressure transmission member, the rotary member and the follower member. The displacement conversion mechanism (7A, 8A) has a first link arm pin-connected between one end portion of the rotary member and the pressure transmission member, and a second link arm pin-connected between the other end portion of the rotary member and the follower member. <IMAGE> |
