A boot fitting structure is fitted onto an axial component to protect it from a dirty environment including outside dust. The boot has a pair of annular grooves and an annular lip between the pair of annular grooves on an inner surface of the boot. The annular lip does not project from an inner surface toward a centerline of the boot. An annular protuberance is provided between the boot and a clamp, through which clamping force from the clamp is concentrated on the annular lip, so that the annular lip is elastically deformed and pushed toward outside of the axial component. Therefore, the axial component can be inserted into the boot without interference between the annular lip and the axial component. Furthermore, the annular lip is free from damage by interference between the annular lip and the axial component.

Boot structure fitting for mechanical joint

In a grinding wheel for use in a grinding machine, a plurality of grinding tips are bonded on the outer peripheral surface of a wheel core having a disk-like shape by bond. On both side surfaces of the wheel core are formed with depressions continuous with the outer peripheral surface of the wheel core. Bond is filled between the outer peripheral surface and the grinding chips, and filled in the depressions of the wheel core to form a bonding layer. Namely, the bonding layer has side portions which extends along both side surfaces of the wheel core in a radial direction.
