A three-wheeled automobile comprises a front cowl for enclosing a front portion of the automobile, and a floor forming a passenger step. The front cowl has on lateral sides thereof rear ends positioned above front wheels of the automobile, and a front end surface positioned forwardly of the front wheels. As a result, a large space is provided between a front wall of the front cowl and a seat. A handle post is provided generally centrally of the floor. The floor has roomy foot platforms located around the handle post. As a result, a space left forwardly of the handle post can be used as a feet accommodating area.

An arm main body of a welding gun is formed of an aluminum alloy. An anodic oxide coating is formed on an entire surface of the arm main body. The arm main body is then machined to remove the anodic oxide coating formed on a power feeing terminal portion and an electrode tip connecting portion which are provided in the arm main body. The anodic oxide coating may be subjected to a sealing treatment with a dispersion liquid in which a magnetic material is mixed in dispersion. Alternatively, the arm main body formed of an aluminum alloy may be subjected to an anodic oxide coating treatment with a treatment liquid in which a magnetic material is mixed in dispersion.

A workpiece is welded successively at a plurality of welding points by a direct-current resistance welding machine with a constant current in a welding current supply period at each of the welding points, and the constant current is varied depending on whether expulsions are produced on the workpiece when it is welded, to determine an expulsion-producing limit current value as a maximum current beyond which expulsions will be produced. The workpiece is welded with a first stepped welding current having a first current value that is smaller than the expulsion-producing limit current value by a predetermined value and a second current value that is greater than the expulsion-producing limit current value, and an average current value higher than the expulsion-producing limit current value, and also with a second stepped welding current having a variation of the second current value based on whether expulsions are produced or not on the workpiece when it is welded with the first stepped welding current.

Method of controlling welding current in direct-current resistance

A cutter for use in an electrode tip dresser, which has a cutter holder for holding the cutter and dresses an electrode tip for a resistance welding apparatus, has a rising portion which has a cutting tooth for cutting a front peripheral portion of the electrode tip and a flat portion which faces a front end surface of the electrode tip. The flat portion has a single cutting tooth for cutting the front end surface of the electrode tip. The single cutting tooth extends from that central point of the cutter as and origin which coincides with an axis of rotation of the cutter holder towards a predetermined radial direction. An origin portion of the single cutting tooth further extends beyond the central point towards a direction which is opposite to the radial direction.

An optical measuring apparatus for use in this method has a projector for radiating a slit light on a workpiece and an image sensing device for picturing an optically cross-sectional image drawn by the slit light radiated on the workpiece. An optical axis of the slit light and an optical axis of the image sensing device cross each other at an oblique angle. Setting windows are set at predetermined positions of the optically cross-sectional image on a screen of the image sensing device. A position of center of gravity of each optically cross-sectional image in each of the windows is measured. An amount of displacement in an X-axis direction of the optically cross-sectional image on the screen is measured. A rate of magnification of the optically cross-sectional image in a Y-axis direction is calculated from the amount of displacement. Setting positions of the windows in the Y-axis direction and sizes thereof in the Y-axis direction are changed depending on the rate of magnification.

For resistance-welding workpieces of metal, an electrode is pressed against superposed regions of the workpieces and an electric current is supplied to the superposed regions to heat the same due to an electric resistance of the workpieces. The electrode has a body having a tip end for pressed engagement with one of the workpieces, and a matrix of tapered teeth disposed on the tip end of the body except for a center of the tip end. The teeth define recesses therebetween. One of the recesses is positioned at the center of the tip end, and the teeth are progressively higher from an outer circumferential edge of the tip end toward the center thereof.

A method and apparatus for assembling exterior parts of a motorcar wherein assembling accuracy errors of a motor car body are determined by measuring positions of a plurality of reference points of said motorcar body. Correction data is calculated relating to respective assembling positions of plural kinds of the exterior parts which form an external shape of the motorcar, the calculation being performed on the basis of measured data obtained in the previous step, while maintaining a correlative relationship among said parts, to eliminate correlative misalignment among said parts due to the assembling accuracy errors of said motorcar body. Each of said parts is then assembled by respective assembling robots to respective assembling position which has been corrected in accordance with the calculated correction data.

A hinge pin couples a first hinge receiver mounted on a vehicle body and a second hinge receiver mounted on a door to be installed on the vehicle body. The hinge pin is removed from the vehicle body and the door to separate the vehicle body and the door from each other after the vehicle body and the door have been coated, and the removed pin engages in a hinge pin engaging member. The hinge pin is fed to a position where the vehicle body and the door are to be assembled together, and the hinge pin is removed from the hinge pin engaging member. Then, the removed hinge pin is pressed into the first and second hinge receivers which are aligned with each other, thereby coupling the vehicle body and the door to each other.
