Abstract
Provided is a slider for a concealed slide fastener that can be made compact and smoothly slide even if large transverse pulling force is applied when a slide fastener is closed. A fastener element standing-up is inclined in a horizontal state, by bringing an element rear end section of the fastener element in sliding contact with a pair of second element guide sections extending toward a rear opening from a front end edge of a lower blade. The fastener element is also in sliding contact with a first element guide section disposed on the outer periphery of a guide column, such that the fastener element becomes in a more horizontal state.
