Abstract: 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.

Abstract: A gap measurement device 1 comprises a light source 5 for projecting light on a gap 3 to be measured, a lens optical system 6 for focusing on an imaging surface 7 a gap image 3A from light transmitted through the gap 3, and a light-receiving element 9 for receiving light of the gap image 3A formed on the imaging surface 7 of the lens optical system 6. A holed mask 8 provided with a light-transmitting hole 8a having a prescribed aperture size is arranged on the imaging surface 7, and the light-receiving element 9 receives the light of the gap image 3A via the hole 8a. A gap size at a point to be measured in an extended gap 3 can be measured by forming an image of the gap with the lens optical system 6 and placing the hole 8a of the holed mask 8 on the point to be measured on the imaging surface 7 of the lens optical system 6.
