An opening/closing device for an opening/closing body is provided with: a resin support member having first and second support wall sections arranged facing each other; and support pins each having opposite axial ends respectively inserted into first and second support wall sections. The opening/closing device is further provided with: pulleys disposed between the first and second support wall sections and having the support pins inserted therethrough; a transmission belt wrapped about the pulleys and coordinated with the opening/closing body; and an electrical drive source for moving the transmission belt while allowing the pulleys to be driven and rotated about the axes of the support pins so that the opening/closing body is opened and closed. The first support wall sections have: insertion holes through which the corresponding axial ends of the support pins are inserted; and slits continuing to the insertion holes so that welds are not present on the first support wall sections after the first support wall sections are formed. Engagement sections are formed at the axial front ends of the support pins which are passed through the insertion holes. The engagement sections have: stepped sections capable of engaging with the peripheral edges of the insertion holes; and tapered sections connected to the stepped section and having a diameter decreasing toward the front ends of the engagement sections.
