The present invention relates to a twisted string actuator. The present invention may comprise: a drive source; driving parts for receiving power from the driving source; driven parts installed in conjunction with the driving parts and receiving power; strings coupled to the ends of the driving parts and the driven parts so as to be twisted or untwisted, and a driving compensation part installed at the ends of the strings to compensate for uneven actuation of each of the strings.

Twisted string actuator

An insert molding apparatus includes: a lower mold including a seating part on which an insert member including a through-hole is seated; an upper mold mounted on the lower mold to receive the insert member seated on the seating part; and a first fixing part including a first head provided in the lower mold and inserted into the through-hole of the insert member when the insert member is seated, and a first drive unit that moves the first head. The first drive unit is moved to adjust a length by which the first head is inserted into the through-hole.
