A strain wave gearing includes an internally toothed gear integrated with an inner ring. A bolt hole is formed in the internally toothed gear. The bolt hole includes a bolt passage hole part, and a screw hole part extending in the direction of an axial line, continuously from the bolt passage hole part. The screw hole part, to which a bolt-fastening force is applied, is formed at a location away in the direction of the axial line from a location adjacent to a radially outer side of an internally toothed gear. Deformation, occurring during fastening of a bolt, at a portion in which the internally toothed gear is formed can be reduced, and adverse effects caused by the deformation such as a decrease in the accuracy of engagement or meshing of the internally toothed gear and an externally toothed gear can be inhibited.

A gap measurement devicecomprises a light sourcefor projecting light on a gapto be measured, a lens optical systemfor focusing on an imaging surfacea gap imageA from light transmitted through the gap, and a light-receiving elementfor receiving light of the gap imageA formed on the imaging surfaceof the lens optical system. A holed maskprovided with a light-transmitting holehaving a prescribed aperture size is arranged on the imaging surface, and the light-receiving elementreceives the light of the gap imageA via the hole. A gap size at a point to be measured in an extended gapcan be measured by forming an image of the gap with the lens optical systemand placing the holeof the holed maskon the point to be measured on the imaging surfaceof the lens optical system
