Abstract: The electromagnetic frictional engagement apparatus includes a housing member in which a housing space is formed, a clutch portion that couples the housing member in a disengageable manner to a shaft disposed so as to be rotatable relative to the housing member, and an electromagnetic coil that generates a magnetic force that actuates the clutch portion. The clutch portion has an outer clutch plate and an inner clutch plate that forms a magnetic path for a magnetic flux generated by the electromagnetic coil. Lubrication grooves through which a lubricant flows are formed in the inner clutch plate. Among the lubrication grooves, the total of groove areas of a portion of the lubrication grooves that is included in the magnetic path is 90 to 110% of a maximum lubrication groove area, so that magnetic flux density resulting from saturation of the magnetic path with magnetic fluxes is not reduced.

Abstract: Provided are a blood collecting puncture device having high safety which can hygienically maintain the inside of a magazine and prevent infection, and the magazine. A blood collecting puncture device has a blood collecting puncture device body removably incorporating a magazine for housing lancets for puncturing human skin. The blood collecting puncture device body has a first housing section for housing not-yet-used lancets and a second housing section for housing used lancets to be disposed of. When a rotor is rotated, individual lancets are sequentially conveyed on a one-by-one basis to a stock position, a puncture position, and a disposal position, and this causes a not-yet-used lancet to be housed in the first housing section and also causes a used lancet to be housed in the second housing section, so that the lancets are separately housed in spaces isolated from each other.
