When a knob of a shift lever device is being assembled, a pair of design frames are assembled to a knob main body, and then a cover is assembled to the knob main body. When the cover is being assembled to the knob main body, ribs of the pair of design frames are inserted into an insertion hole in the cover. The pair of ribs are put into surface contact with one another in a left-and-right direction, and distal end portions of the pair of design frames are put into surface contact in the left-and-right direction. Consequently, the formation of a gap between the distal end portions of the pair of design frames may be inhibited.

Shift device

A surface inspection apparatus for inspecting a shape of an inspected surface of an object to be inspected includes: a supporting unit capable of supporting the object in a state in which the inspected surface is in a substantially vertical state; and a moving state which moves the object in a substantially vertical direction while the inspected surface is maintained in the substantially vertical state.

Surface inspecting apparatus

A surface inspecting apparatus for inspecting a shape of a surface of an object to be inspected is disclosed. The surface inspecting apparatus includes a mounting base for mounting the object, a positioning device for positioning the object to an inspecting position on the mounting base, a memory for storing position specifying information for specifying a two-dimensional position of the object when the object is positioned, an inputting device for inputting an outer shape data of the object, and edge position determining device for acquiring an edge position of the object based on the stored position specifying information and the inputted outer shape data.

Surface inspecting apparatus that determines an edge position of an object

A surface inspection apparatus for inspecting a surface of an object to be inspected, includes: a projecting optical system which projects an inspection light to the object surface via a reference surface; a pick up unit which picks up surface interference fringes formed by reflected light from the reference surface and reflected light from the object surface; and an arithmetic unit which calculates a shape of the surface of the object based on the picked up interference fringes. The projecting optical system includes a laser light source that emits, as the inspection light, pulsed laser light having a pulse width and a pulse quiescent time capable of preventing formation of rear face interference fringes which are formed by the reflected light from the object surface and reflected light caused by the inspection light being reflected from its rear face, the object allowing the inspection light to pass therethrough.
