摘要： A glow plug (1) including a metallic shell (2) having a forward end portion (20) having an outer peripheral surface whose diameter increases toward the rear end side with respect to the axial direction, the forward end portion (20) coming into contact with a seat surface (55) formed on an internal combustion engine (50). The outer peripheral surface of the forward end portion (20) includes a first, second and third contact surfaces (21), (22) and (23), respectively, which differ in imaginary line angle from one another, the imaginary line angle of each contact surface being an angle which is formed, as viewed on a cross section including an axis C1, between two straight imaginary lines connecting inflection points of the contact surface at opposite ends of the contact surface. At least one of the contact surfaces is a curved surface which bulges outward.

摘要： There are provided an electrode tip dressing apparatus and an electrode tip dressing tool for resistance welding, which are miniaturized by reducing a rotational driving-force of a dressing tool. By adjusting a curvature radius of a dressing portion 4 of a dressing tool 2, a contact width, wherein a top electrode tip 5 abuts to the dressing portion 4 of the dressing tool 2, is adjusted from a rotational center of the dressing tool 2 to the outer side of the dressing tool 2. Dressing work done with the dressing tool 2 is thus made to be constant at the whole area of the dressing portion 4, from the rotational center of the dressing tool 2 to the outer side of the dressing tool 2. Accordingly, excess dressing work, which brings decline of productivity, can be avoided, thus enabling to dress the top electrode tip 5 with the minimal dressing work. A rotational driving-power of the dressing tool 2 is thereby reduced, enabling to labor-save and miniaturize the electrode tip dressing apparatus.
