Abstract: A shift lever device includes a shift lever having a pivot shaft formed at a base end of the shift lever integrally and a base having an opening formed to allow the shift lever to be inserted into the base and a pair of bearing parts formed so as to lie on opposing sides of the opening. The pivot shaft extends along a direction intersecting with a longitudinal direction of the shift lever. Each of the bearing parts has a bearing hole formed in the bearing part to adjoin the opening, a guide groove formed in the bearing part to communicate with the bearing hole, for introducing the pivot shaft into the bearing hole and a bearing bush which is to be inserted between the pivot shaft and the bearing hole. The bearing bush has a latch hook provided to engage with an interior of the bearing hole.

Abstract: A drill which includes a cylindrical main body and a shank contiguous to each other, and which is to be rotated about an axis of the cylindrical main body in a predetermined rotating direction, for machining a hole in a workpiece. The cylindrical main body has flutes which are formed in the cylindrical main body and extend from an axially distal end portion of the cylindrical main body toward the shank, so as to provide cutting edges in the axially distal end portion of the cylindrical main body. The cutting edges cooperate with each other to define a point angle which is not smaller than 170° and is smaller than 180°. Each of the cutting edges is substantially straight as seen in a direction perpendicular to the axis, or is curved such that each cutting edge is convexed as seen in the direction perpendicular to the axis.

Abstract: A drill including a shank portion and a cylindrical body portion contiguous to each other. The cylindrical body portion includes (a) primary cutting edges and secondary cutting edges formed in its axially distal end portion such that each of the secondary cutting edges is located on a radially inner side of the corresponding primary cutting edge; (b) primary rake surfaces of the primary cutting edges and secondary rake surfaces of the secondary cutting edges; and (c) inclined surfaces each of which extends from the corresponding secondary rake surface to a periphery of the cylindrical body portion, and is inclined such that an axial distance between each of the inclined surfaces and the shank portion is reduced as viewed in a direction substantially perpendicular to the corresponding secondary cutting edge, from the corresponding secondary rake surface toward the periphery of the cylindrical body portion.

Abstract: A column shifter has an impact absorbing structure. The column shifter includes a shift lever rotatably supported to a steering column. The column shifter includes a bellcrank supported to the steering column and being rotatable by the shift lever about the rotation center to operate a transmission. The bellcrank includes a first link angularly-displaced by the shift lever. The bellcrank includes a second link separated angularly from the first link about the rotation center. The second link includes a distal end connected to the transmission. The second link includes a strength weakened portion between the distal end and the rotation center.

Abstract: A sealing structure for an automatic transmission shift control device comprises a boot interposed between a vehicle floor and a support member, which is a single piece resinous molding, of the transmission shift control device for providing a seal therebetween, and having on the lower side thereof a first seal projection in contact with the vehicle floor. A looped groove of a trapezoidal cross section is formed on the bottom of the support member. A second looped seal projection of a trapezoidal cross section and fittingly engageable in the groove in the boot is formed in the boot on the upper side of the boot. The first seal projection and the second seal projection are similar in loop shape and are located correspondingly on opposite sides of the boot.

Abstract: A gear shifting device includes a frame, a shifting lever with a positioning pin pivotably attached to the frame, a locking member pivotably attached to the frame for preventing the positioning pin from falling when the shifting lever is in a Parking position, an actuator for operating the locking member and a hand-operated locking disengageable mechanism. The hand-operated locking disengageable mechanism has a disengaging member slidably attached to the frame for moving the locking member to the unlocked position, a compression spring for applying repulsive force on the disengaging member, a core pin removably attached to the frame so as to oppose the disengaging member, the core pin being rotatable between its locked position and unlocked position by aid of a tool and a lid member removably attached to the frame so as to cover the core pin.

Abstract: A shift lever apparatus for an automatic transmission includes first and second levers, which are pivotally supported on the positioning plate by a shaft, and a lock lever, which is pivotally supported by a shaft parallel to the shaft of the second lever. The apparatus also includes a spring for energizing the first and second levers so as to draw the arms of the first and second levers close together and to restrain the positioning pin positioned at the parking position. Even though an actuator is connected to and actuates the lock lever so as to rotate it in predetermined directions, since the lock lever of the arm is pressed by the first lever when the positioning pin is positioned at the parking position, the lock lever can be stabilized under The positioning pin to lock it at the parking position.
