A force sensorincludes: a force sensor chipincluding an action portion, a connecting portionon which strain resistive elements are disposed, and a support portionfor supporting the action portionand the connecting portion; an attenuatorincluding an input portionto which an external force is input, a fixing portionfor fixing the force sensor chip, and a transmission portionfor attenuating the external force and transmitting the attenuated external force to the action portion; a first glass memberdisposed between the action portionand the transmission portionand a second glass memberdisposed between the support portionand the fixing portion, through which glass membersthe force sensor chipand the attenuatorare joined. A single or more glass beamsjoins the first glass memberand the second glass membertogether as a single member.

A force sensor comprises a force sensor chip, and a buffering device for dampening and applying incoming external force to the force sensor chip. The buffering device comprises an input portion to which external force is input, a sensor mount for fixing the force sensor chip to the exterior, a dampening mechanism for dampening external force, and a transmission portion for transmitting the dampened external force to the active sensing portion.

A cup-shaped grindstone for grinding an end face of an annular portion of a work to form tooth grooves in the end face includes a grinding portion provided around an outer periphery of a disk portion. Abrasive grains of CBN are electrodeposited on each of first, second and third grinding faces of the grinding portion. Cooling-liquid ejecting bores are provided in a lower end of the first grinding face. To form the tooth grooves, the following steps are carried out: a rough-finish processing step cuts the tooth grooves by intermittently feeding the cup-shaped grindstone in a predetermined amount at a time, and a finish processing step of finishing the tooth grooves by retaining the cup-shaped grindstone at a predetermined position after the rough-finish processing step. During both steps, a cooling liquid is supplied from cooling-liquid ejecting bores defined in the first grinding faces of the cup-shaped grindstone.
