Abstract: Provided is a water absorbent sheet retaining mat which can retain a water absorbent sheet easily and surely. A water absorbent sheet retaining mat for retaining a water absorbent sheet having a first polygonal contour, includes: a mat member having a second polygonal contour defined by mutually opposing a first main plane and a second main plane; and at least one retaining member having a slit member including at least one slit formed in a top surface at a first predetermined height from the second main plane for accepting a part of perimeter of the water absorbent sheet being inserted therein.

Abstract: A connector for an animal has a stopper mechanism for enabling or disabling a slide bar to be pushed back. The connector for an animal includes a hook member; a stem portion extending from an end of the hook member in a first direction; a slide bar for being reciprocated in the first direction to open or close the hook member; a lock member for being installed around the stem portion to rotate therearound with the first direction as a rotation axis; and an operating member for being connected to the slide bar so as to protrude in a second direction perpendicular to the first direction, the lock member including a cylindrical member with a cylindrical space formed therein for housing the stem portion rotatably and projection extending from a part of the hook member side end of the cylindrical member toward the hook member by a predetermined length.

Abstract: A coupler includes: a hook portion; a stem portion extending from an end portion of the hook portion in a first direction; a slide bar closing and opening the hook portion by reciprocating in the first direction; a connection ring rotatably connected to an end of the stem portion with respect to the first direction, having a predetermined contour, and extending in a second direction perpendicular to the first direction; at least one projection extending from an outer circumferential portion of the connection ring in the second direction by a predetermined length; and an operation member connected to the slide bar and extending toward the connection ring. The operation member abuts only the projection when being moved in the first direction.

Abstract: Provided is a cat playing tool expected as an optimum communication tool between cats and people, employing means for optimally producing both of a relaxing effect obtained by an Actinidia polygama powder and an effect of deodorizing bad odor by a deodorant component. A cat playing tool includes a printed layer having an Actinidia polygama powder, a deodorant component, and a binder applied thereto, and is configured so that the above-described printed layer is held by at least one of two sheets (a first sheet and a second sheet) and that the above-described first sheet and the above-described second sheet are joined together at the peripheries thereof so as to form a bag shape holding the above-described printed layer therein.
