Abstract: A plug and a socket constitute a buckle. The plug includes a plug base and a pair of legs. At least one of the pair of legs includes a first extension extending from the plug base in an insertion direction of the plug, a second extension extending from the first extension in an inward width direction of the plug, an engagement portion provided on the first extension or the second extension to be engageable with a to-be-engaged portion of the socket in a detachment direction of the plug, and an operation portion provided on the second extension. When a force in the detachment direction is applied on the operation portion, the first extension is elastically deformed in the width direction of the plug in such a manner that a position of the engagement portion shifts from an engagement position to a disengagement position with respect to the to-be-engaged portion.

Abstract: This tape attachment has: one or more crossbar parts that extend along a first direction; a pair of side support parts that support the crossbar parts; and a whistle part provided with a blowing hole and a discharge hole, the whistle part having a hollow section in which the pressure of air guided from the blowing hole is increased, the hollow section being positioned on the downstream side in the air passage direction in relation to the discharge hole, and the hollow section being provided in at least a part of the crossbar parts and the pair of side support parts. It is thereby possible to reduce the size of a tape attachment provided with a whistle function.

Abstract: A connector includes a connector body and an attachment body. The connector body includes a pair of connecting holes, and the attachment body includes a connecting shaft. Connecting holes are formed in the pair of connecting hole portions, and the connecting shaft is provided with a bulge portion located in the connecting holes. Contact flat surfaces are formed in the connecting hole portions and the bulge portion, the contact flat surfaces being configured to come into surface contact with each other in a pulling direction of the connector body and the attachment body.

Abstract: A plastic molded product includes a plastic body provided with a plurality of holes, which are recessed in a common depth direction, on a surface of the plastic body. The holes include: an inner surface including an inlet a specific reference plane perpendicular to the depth direction and including at least a portion of the inlet and a depth reference point, which is spaced away from a center point on an inlet side of the specific reference plane toward a bottom side of the hole, the depth reference point being spaced away by a distance equal to ¼ of a maximum value of an inlet side bore diameter on the specific reference plane. A deepmost portion of the inner surface of the hole is in a position which coincides with the reference point or is deeper than the reference point toward the bottom side.

Abstract: A side-release buckle includes a plug and a socket for inserting and engaging the plug, and when a cross section of the engaging surface is observed from an in-plane direction of the first mold mating surface defined by a first parting line of the plug, and from an direction perpendicular to an insertion direction, a surface to be engaged is located on the opposite side to a first belt winding portion with respect to the first mold mating surface, and has a first engaging surface forming an angle A1 with the first mold mating surface of 87° or more and 90° or less.

Abstract: The lock member includes: a plate-like base portion positioned on a top side of the socket; a holder retaining the base portion to the socket; an operating portion connected to the base portion and movable in a direction intersecting the base portion by an external operation; and a lock portion restricting disengagement of the engaged portions and the engaging portions. The lock portion is positioned in the socket and connected to the operating portion via a joint inserted in the cutout. Without the external operation, the lock portion is present in movement paths where the engaging portions move to be disengaged from the engaged portions. When the operating portion is moved by the external operation, the lock portion is moved away from the movement paths.

Abstract: A side release buckle includes a plug and a socket into which the plug is inserted for engagement. The plug includes: a base provided with a belt attachment; a pair of legs projecting from the base; an engaging portion formed to the legs; and a connecting portion connecting the legs to each other. The socket includes: a body provided with a belt attachment and an insertion opening; a housing space formed in the body and housing the legs inserted from the insertion opening; an engaged portion formed in the body and engageable with the engaging portion; and a cutout dented toward the insertion opening from an edge of the belt attachment. The cutout is formed over an area surrounded by the legs and the connecting portion when the legs and the connecting portion are housed in the housing space while the engaging portion and the engaged portion are engaged.
