Abstract
A needle assembly includes a needle hole having an inside diameter that is greater than an outside diameter of a needle, and by a moving-side guide integrally provided to a needle tip cover being engaged with a fixed-side guide fixedly provided to the needle, a guide mechanism is provided to guide the needle tip cover from a proximal end side towards a distal end side of the needle while maintaining a state of noncontact with the needle, and to guide the needle tip cover to a position where the needle tip cover covers the needle tip while deviating the needle tip cover in a direction in which the needle hole goes away from a center axis of the needle at a position beyond the needle tip, and avoiding contact of the needle tip with the needle hole.
