Abstract

A needle thread passing device small-sized and conveniently stowable. A needle receiving member (34) has formed therein a needle inserting hole (34c) and a thread inserting slit (34e) having an angle relative to the needle inserting hole (34c). A thread passing member (42) is adapted to be movable between a position at which the thread passing member (42) is separated from the needle receiving member (34) and a position at which the thread passing member (42) is located proximate to the needle receiving member (34). Also, the thread passing member (42) has a thread passing pin (48b) which can, when the thread passing member (42) moves fromthe separated position to the proximate position, push out a thread, inserted in the thread inserting slit (34e), into a needle hole (52a) in a needle (52) inserted in the needle inserting hole (34c). A cover (32) is adapted to be movable relative to a body (30) in which the needle receiving member (34) is housed. The thread passing member (42) is constantly urged to the position at which the thread passing member (42) is separated from the needle receiving member (34). The cover (32) is adapted to be movable between a restraining position for restraining the thread passing member (42) at a position at which the thread passing member (42)is located proximate to the needle receiving member (34) and a permitting position for permitting the thread passing member to move between the separated position at which the thread passing member is separated from the needle receiving member and the proximate position at which thread passing member is located proximate to the needle receiving member.

Description

technical field [0001] The present invention relates to a needle thread threading device for simply threading a thread in a needle hole. Background technique [0002] Conventionally, as such a needle thread threading device, a device described in Patent Document 1 (Japanese Patent No. 3315364 ) is known. According to this device, a needle insertion cylinder having a bottomed needle insertion hole is erected on a main body having a base surface, and a needle connecting the inserted needle is formed at the lower part of the needle insertion cylinder in a direction intersecting the needle insertion hole. For the threading hole of the threading hole, a thread mounting part is provided near the entrance of the threading hole, and the thread locking piece provided on the working part is inserted through the working part provided in the main body by the pressing force of the pressing part provided on the main body. It can be freely set in the threading hole. When the pressing mem...
