The dicing die-bonding film of this invention comprises a pressure-sensitive adhesive layer on a supporting base material and a die-bonding adhesive layer on the pressure-sensitive adhesive layer, wherein a releasability in an interface between the pressure-sensitive adhesive layer and the die-bonding adhesive layer is different between an interface corresponding to a work-attaching region in the die-bonding adhesive layer and an interface corresponding to a part or the whole of the other region, and the releasability of the interface is higher than the releasability of the interface. According to this invention, there can be provided a dicing die-bonding film excellent in balance between retention in dicing a work and releasability in releasing its diced chipped work together with the die-bonding adhesive layer.

An auxiliary connector (14) has cavities (35) for receiving terminal fittings (13) and resilient locks (40) that deform in a deforming direction (DD) that extends along an arranging direction of the cavities (35). The locks (40) are configured for holding the terminal fittings (13) in the cavities (35). A retainer (39) is formed integrally with the auxiliary connector (14) via a hinge (75) at an opening edge of a retainer accommodating hole (73) in a side surface of the auxiliary connector (14) facing a direction intersecting the deforming direction (DD) of locks (40). The retainer (39) has locking protrusions (78) for redundantly locking the terminal fittings (13) in the cavities (35). The locking protrusions (78) of the retainer (39) are arranged at substantially the same positions for all cavities (35).

A joint is provided between a transmission operating member of a transmission and a control rod of a transmission gear control mechanism. The joint includes rigid stopper rings for rigidly stopping deformations of resilient deformable members in predetermined directions and thereby rigidly stopping movement of outer sleeves of an outer sleeve unit in the directions crossing joint pins at right angles. The stopper rings are fittingly interposed between the outer sleeves and channel-like end portions of the transmission operating member such that the transmission operating member and control rod are relatively less movable in the direction crossing their axial directions at right angles.
