Abstract: A brush head is provided on the front surface at a distal-end-side part of a neck of a replaceable brush. A fitting shaft portion is provided on a planting base of the brush head so as to protrude rearward and penetrate through a support wall portion of the neck. A shaft hole is formed at a rotation center of a brush head body of the brush head so as to extend frontward from a rear surface of the brush head body. The neck has ahead support shaft mounted to the shaft hole so as to rotatably support the brush head. A front end of the head support shaft is located frontward of a rear surface of the planting base, and power from the driving portion is transmitted to a rear part of the fitting shaft portion.

Abstract: Provided is an oral cleaning device capable of ensuring a sufficient ejection pressure for a cleaning liquid while employing a small and low-cost electric air pump with a low output. An oral cleaning device is provided with an air-tightly closable cleaning liquid tank 2 which stores a cleaning liquid, a cleaning liquid supply passage 24 which has an ejection port 4a for ejecting the cleaning liquid into the oral cavity on one end and an introduction port 23a open inside the bottom part of the cleaning liquid tank 2 on the other end, and an electric air pump 44 which supplies air into the cleaning liquid tank 2 to pressurize the inside of the cleaning liquid tank 2. The cleaning liquid inside the cleaning liquid tank 2 is supplied to the ejection port 4a through the cleaning liquid supply passage 24 by air pressure inside the cleaning liquid tank 2. An air introduction hole 71 which is open on the midway part of the cleaning liquid supply passage 24 is provided and part of the air supplied to the cleaning liquid tank 2 from the air pump 44 is supplied to the cleaning liquid supply passage 24 through the air introduction hole 71 to eject the cleaning liquid in a pulsatile manner from the ejection port 4a.

Abstract: A molded article (20) for an oral care product includes a primary molded part (P) that includes a covering target part (PC), a secondary molded part (Q) that includes a covering part (Q40) covering the covering target part (PC), and an exposed structure (500) that includes one or a plurality of penetration parts (P100) penetrating the covering part (Q40). The penetration part (P100) includes an exposed surface exposed with respect to the covering part (Q40). The penetration part (P100) is provided in the primary molded part (P) such that a force received by the primary molded part (P) from a resin material corresponding to the secondary molded part (Q) so as to deform the primary molded part (P) in a secondary molding step of molding the secondary molded part (Q) is able to be transferred to a mold through the exposed surface.
