摘要： An actuator is proposed. A housing and a housing cap constitute an exterior of the actuator, and a driving pin is installed by passing through an inner space of the housing such that the driving pin moves rectilinearly. A permanent magnet and an outer iron core are stacked and installed at the inner surface of the housing, that is, in the inner space. The permanent magnets and the outer iron core are stacked such that a set of permanent magnet and outer iron core in which the permanent magnet is stacked at each of opposite sides of one outer iron core.

摘要： An actuator is proposed. A housing and a housing cap may constitute the exterior of the actuator, and a driving pin may be installed in an inner space of the housing such that the driving pin is moved by being guided by a guide. A cylindrical bobbin having one open end portion may be installed at the driving pin to be moved integrally therewith, and a coil may be installed at the bobbin. A permanent magnet and an iron core may be stacked in the inner space by the guide. A pin iron core may be provided at the driving pin, and a pin coil may be installed in a groove of the pin iron core.
