摘要： Structure of a cross universal joint is achieved in which the fact that an excessive torque was applied to a universal joint due to a collision accident or mishandling can be easily determined afterwards. Protrusions 20, which are straight lines as seen from the outside surface sides of linking arm sections 15c of a yoke 12c, are formed on the outside surfaces of the linking arm sections 15c. When an excessive torque acts and the linking arm sections 15c are plastically deformed, the protrusions 20 change from a straight line to a non-straight line. From this change it is possible to easily confirm that an excessive torque has been applied to a cross universal joint that includes this yoke 12c. Moreover, when the space between the inside surfaces of the linking arm sections 15c is taken to be D, and the length in the axial direction of the linking arm sections 15c is taken to be L, the dimensions of the parts of the yoke 12c are regulated so that the relation 3

摘要： A steering control apparatus in which a steering shaft coupled to a steering wheel is mechanically separated from a turning mechanism to turn a turning wheel, a steering angle of the steering wheel is detected, and the turning mechanism turns the turning wheel by a turning angle corresponding to the steering angle, includes a hypercycloidal mechanism including an external tooth gear revolving in a housing according to rotation of the steering wheel, an Oldham coupling mechanism to extract only a self-rotating movement in a rotation movement of the external tooth gear as a self-rotating movement of a rotation disk, and a rotation regulating mechanism by engagement between a groove formed in the rotation disk and a projection projecting from the housing. Then, a compact mechanical steering angle regulating mechanism is provided in which an allowable rotation range of the steering wheel is made ±180 degrees or more, and a low output and low capacity motor is used, and reduction in size and in cost of the apparatus is realized.

摘要： An electric power steering device having a torque sensor for detecting torque by using a coil provided in an electromagnetic yoke. A terminal block projects to the radial outside and axial outside with respect to an axial line of a substantially cylindrical coil bobbin accommodated in the electromagnetic yoke by a predetermined offset amount and is provided in the coil bobbin. The terminal block has press-fitting holes for press-fitting and fixing connection pins for connecting the coil winding and a sensor circuit substrate, wherein the press-fitting holes have air-purging holes communicating with the outside.
