The insert molding method comprises an insert molding step for separately pre-heating an insert member and a metal mold and injecting a molten resin, a step for holding the molding in the metal mold, and a step for gradually cooling the molding at a room temperature after taking out from the metal mold. By the method, the molding free from resin crack and having excellent environmental resistance characteristics can be realized. In addition, the method comprises the steps of injection-molding the molten resin in the state of metal gears and metal molds for molding being heated to predetermined temperatures and coating the surfaces of the metal gears with the resin. By the method, resin-coated metal gears not causing the resin crack even after the molding and in their use under no-lubrication and having excellent strength, rigidity, accuracy, impact resistance, fatigue resistance, noise reducing properties, and wear resistance can be realized.

摘要： A power transmission device includes a pulley (4) and a hub (11) that are arranged on the same rotation axis, and a connecting member (13) that connects these rotation bodies. The power transmission device includes a first connecting structure (14) that connects one end portion (13a) of the connecting member to the pulley so that one end portion (13a) cannot be separated, and a second connecting structure (15) that connects the other end portion (13b) of the connecting member to the hub so that the other end portion (13b) can be separated. The second connecting structure includes a columnar body (21) that extends through the other end portion (13b) of the connecting member (13) in the axial direction, a head portion (28) that is provided on the columnar body (21), a slit (22) of the connecting member (13), and a belleville spring (29) that presses the connecting member (13) against the rotation body. The other end portion (13b) of the connecting member (13) is formed to be larger than the remaining portion of the connecting member (13) when viewed from the axial direction. A recessed portion (16) that is recessed toward the outer peripheral side of the hub (11) is formed at a portion of the other end portion (13b) that is directed to the shaft center side of the hub (11). The power transmission device capable of setting with high accuracy the operation load of a torque limiter that cuts off power transmission can be provided.

摘要： A power transmission device includes a pulley (6) serving as a rotation member, an elastic member serving as a power transmission member, a fixing screw extending through these, and a nut that sandwiches the pulley (6) and the elastic member in cooperation with the fixing screw. The power transmission device includes a nut holder (25) attached to the pulley (6) via a hooking structure. The hooking structure includes a through hole (14) of the pulley (6), a hook (13) of the nut holder (25), which can be inserted into the through hole (14), and an elastic piece (33) located near the hook (13). When the nut holder (25) is rotated in one of rotation directions with respect to the pulley (6) in a state in which the hook (13) is inserted into the through hole (14), a hooking piece (36) of the hook (13) comes into contact with the pulley (6), and a pawl portion (43) of the elastic piece (33) engages with the opening edge of the through hole (14). It is possible to provide a power transmission device that employs a structure capable of easily attaching the nut holder and prevents the nut holder from being disengaged by a pressing force that presses the fixing screw against a nut.
