Abstract: Provided is a plug lock mechanism allowing a locking member to be retained at any position with a simple structure. The plug lock mechanism has a plug that can be plugged into and pulled out of a power receiving connector as a female connector; and a locking member that is swingably and axially supported by a pair of shaft receiving portions that are provided across the power receiving connector. This locking member coaxially has a pair of shaft portions that are located at both ends thereof, and central axes X1L and X1R of shaft receiving holes of the shaft receiving portions are slanted with respect to a central axis of the shaft portions. Thus, the locking member can be retained at any position via a friction caused by allowing the shaft portions to be pressed against part of the inner walls of the shaft receiving holes.

Abstract: Provided is a Stirling cycle engine capable of being downsized without decreasing an assembling efficiency. A flange section as a fitting section is formed on one end of an inner core. A retainer plate as a retaining member for the flange section, holds and fixes the same with the aid of a second side surface of a mount integrally formed on a proximal end section of a cylinder, thus substantially coaxially arranging the cylinder and inner core. Accordingly, regardless of a thermal expansion difference between the cylinder and inner core, generation of impurity gas can be prevented; deformations of the cylinder and the inner core; and tremble of the inner core. Further, a conventional proximal end portion of the cylinder is not needed for fixing the inner core, thus reducing an outer diameter of a driving mechanism, eventually, an outer diameter of a casing.

A motor serving as a drive section is activated allowing a reciprocating drive means to repeatedly deform the body plate coupled thereto between an upwardly-deflected curved concave position and a downwardly-deflected curved convex position along the axis line A, thereby allowing each distance among a plurality of the projections to open and close-repeatedly to provide an repetitive action of kneading and pushing/stretching the scalp. Accordingly, the scalp massage and the scalp and hair wash are achieved.
