Abstract: Provided are a movable contact, a variable resistor, and a method for manufacturing a movable contact that can suppress a cost increase. The movable contacts are spaced apart from each other. The variable resistor, having a resistor, an electrode and the movable contact, comprises: a first wire rod group which has a plurality of first wire rods made of a precious metal and in which the plurality of first wire rods are arranged along the resistor; a second wire rod group which has a plurality of second wire rods made of a metal other than the precious metal and in which the plurality of second wire rods are arranged along the electrode; and a shaft-shaped member which is disposed to cross the first wire rod group and the second wire rod group and is welded to the first wire rod group and the second wire rod group.

Abstract: A piston boot has an annular fitting section which is formed on one end side of a bellows section, encloses an annular metallic member and is fitted to a stepped section. The fitting section has an outer peripheral surface section which comes into contact with an inner peripheral surface of the stepped section, and an annular plane section which comes into contact with an annular wall surface section of the stepped section. A plurality of holes each having a bottom surface at a position of the metallic member or a position near the metallic member are opened to the plane section.
