摘要:
A support device of a propeller shaft comprises an annular bracket fixed to a floor member of a vehicle body; an annular elastic member disposed in the annular bracket; an annular supporting structure disposed in the annular elastic member and rotatably supporting a cylindrical given portion of the propeller shaft through a ball bearing unit; and an annular seal member intimately disposed in an annular space defined between the annular supporting structure and the cylindrical given portion of the propeller shaft. One of outer and inner cylindrical surfaces of the annular seal member is in slidable contact with either one of an inner cylindrical surface of the annular supporting structure and an outer cylindrical surface of the cylindrical given portion of the propeller shaft. A rust-proofing member is further provided, which is disposed on either one of the inner cylindrical surface of the annular supporting structure and the outer cylindrical surface of the cylindrical given portion of the propeller shaft, to which the outer or inner cylindrical surface of the annular seal member directly and slidably contacts. The rust-proofing member is made of a rust-resistant material.

A shaft coupling includes an annular plate having a proper axial flexibility. The annular plate is formed with mounting holes. A first group of coupled portions are fixedly connected to an input shaft, whereas a second group of coupled portions are fixedly connected to an output shaft. The first and second groups of coupled portions are coupled with each other through the annular plate placed therebetween, so that the first and second groups of coupled portions circumferentially alternate with each other. The annular plate has coupling arm portions each extending between two adjacent mounting holes to absorb axial vibrations. A radial width of the coupling arm portion is dimensioned to be narrower than a radial width of a peripheral region of each of the mounting holes. A length of the coupling arm portion is dimensioned to be longer than a distance between the two adjacent mounting holes.

An injection needle assembly includes a needle tube having a needle tip to be stuck into a skin, a first member, a second member, an adjustment portion, and a pressing force restricting member. The first member holds the needle tube and the second member holds the first member movably toward the axial direction of the needle tube. A discharge portion of the syringe is fitted into this second member. The adjustment portion is provided at the periphery of the needle tube and includes a needle protrusion surface which abuts the skin in a case in which the needle tube is stuck to the living body. The pressing force restricting member is arranged between the first member and the second member, and restricts the pressing force added from the first member to the skin.

An injection aid is a tool used by being attached to an injection device having an injection needle and a syringe, and includes an aid main body and a tapered guide. The aid main body includes; an engagement part to be engaged with the syringe; a hollow part through which the injection needle penetrates; and a needle-protruding surface from which a needle tip part of the injection needle protrudes and which is brought into contact with skin when sticking the injection needle into a living body. The tapered guide is arranged in the hollow part of the aid main body and includes an inner surface that becomes continuously reduced in diameter toward the needle-protruding surface.

A connector includes a male connector section having a male-side cavity, a female connector section having a female-side cavity to which another male connector section the same as the male connector section can be connected, a seal member formed from an elastic material for maintaining liquid tightness between the connector sections when the other male connector section and the female connector section are connected to each other, and lock mechanisms disposed respectively on the male connector section side and the female connector section side for maintaining the connected condition of the connector sections when the other male connector section and the female connector section are connected to each other. Each of the lock mechanisms has a male lock section formed to project in parallel to the direction of connection between the connector sections, and a female lock section, which is formed adjacent to the male lock section and parallel to the direction of connection, and to which another male lock section the same as the male lock section can be coupled.
摘要:
A connector having a male-side connection section, a liquid flow section where a liquid flow space communicating with the inside of the male-side connection section is provided, a first female-side connection opening and a second female-side connection opening, and a first valve body and a second valve body that are made from an elastic material. A side slit of the first valve body and a side slit of the second valve body face the liquid flow space. When a tube body is connected to the first female-side connection opening, the inside of the tube body and the inside of the male-side connection section are communicated through a top slit, the side slit, and the liquid flow space. When a tube body is connected to the second female-side connection opening, the inside of the tube body and the inside of the male-side connection section are communicated through a top slit, the side slit, and the liquid flow space.

A connector includes a housing having a first female-side connecting port, a liquid circulation space, and a male-side connecting section communicating with the liquid circulation space, a first valve disk made of elastic material and having a hollow section and a top slit formed in the top and received in the housing, a pin movably installed in the housing, and an urging section for urging the pin axially. In this connector, the top slit spreads and communication is established between a tube interior and the hollow section, and at the same time the top of the pin is pressed to cause the pin to move axially, enlarging the clearance between the hollow section and the pin, thereby establishing communication between the tube interior and the male-side connecting section interior successively through the top slit, the hollow section and the liquid circulation space.

A connector having a male-side connection section, a liquid flow section where a liquid flow space communicating with the inside of the male-side connection section is provided, a first female-side connection opening and a second female-side connection opening, and a first valve body and a second valve body that are made from an elastic material. The first valve body has a head section and a neck section that connects the head section and a liquid flow section and is thinner than the head section. In the first valve body is formed a slit penetrating from the top face of the head section to the liquid flow space. When a male lure is connected to the first female-side connection opening, the slit is opened and the flow path in the male lure and the inside of the male-side connection section are communicated through the liquid flow space.
