An outside locking lever of a lever mechanism section in a lock mechanism of a vehicle door lock apparatus includes a hub portion being rotatable relative to a housing and having a connection subportion to which an inner end portion of a rod is connected in a torque transmittable manner; an arm portion extending radially outward from the hub portion and linked to an active lever; a hub-side engagement subportion provided on the hub portion and engaged in the vehicle interior-exterior direction with a first support portion of the housing; an arm-side engagement subportion provided on the arm portion and engaged in the vehicle interior-exterior direction with a second support portion of the housing; and a fragile portion provided between the two engagement portions and being breakable with a force of a predetermined value or greater. A space for allowing breakage at the fragile portion is provided within the housing.

A child protector mechanism includes a base member, a first lever, a second lever, a bush arranged between the first lever and the second lever, a child protector lever for moving the bush to an unset position or a set position, and a position retaining mechanism provided between the first lever and the bush. The bush is retained at each of the unset position and the set position by the position retaining mechanism provided between the first lever and the bush. Therefore, when assembling the bush and the first lever to the base member, the bush is retained at a predetermined position (for example, unset position) with respect to the first lever so that the bush does not move. Thus, the easiness of assembly of the bush and the first lever and the easiness of assembly of the child protector lever are excellent.

Provided is a position holding device for a rotating lever, which includes a rotating lever and a torsion spring, and is capable of elastically holding the rotating lever at the two positions including a first position and a second position. The torsion spring includes a coiled part, and a first arm part and a second arm part each extending from the coiled part and facing each other across an engagement portion of the rotating lever. The first arm part includes a mountain portion formed at an intermediate portion thereof. The second arm part includes an urging portion. As a result, an urging force generated by the urging portion can be applied to the rotating lever as a braking force against an urging force generated by the mountain portion. Consequently, it is possible to reduce an abutment noise generated when the rotating lever abuts against a stopper member.

A cam unit comprising a main cam; a first auxiliary cam provided in contact with the main cam; a second auxiliary cam provided in contact with the first auxiliary cam; a rod provided between the main cam and the second auxiliary cam and having a slenderly shaped hole in which the peripheral portion of the first auxiliary cam is located in contact with the rod so that the rod is swung while being guided by the first auxiliary cam; a motion transmission means secured to the rod and located on the peripheral portion of the main cam so as to move the rod in accordance with the contour of the main cam; a jump prevention means secured to the rod and located on the peripheral portion of the second auxiliary cam so as to prevent the motion transmission means from jumping from the main cam; and a shaft extending through all the cams. A positive cam is constituted by the main cam, the auxiliary cams and the rod without guiding a driven member to straightly move it. A motion is directly transmitted to a swinging member by the cam unit.

An articulated robot joint includes a coupling member 13 having a hollow cylinder 13a rigidly mounted to a lower arm 2 and rotatably journaled to an upper arm 1. An offset crank 13c extends from one end of the cylinder, and has a mounting hub 13d at the end of a radial arm thereof coupled to an axially disposed output shaft of a motor and harmonic drive unit 5, 6. A power/control cable 3 is threaded through the hollow interiors of the arms, and traverses the joint via the hollow cylinder.

An industrial robot's articulate device comprises: a first arm; a second arm rotatably connected to the first arm; an electric motor for rotating the second arm; a transmission shaft rotatably supported by the first arm for transmitting the output of the electric motor to the second arm; and a detecting mechanism for detecting the position of the second arm with respect to the first arm. The detecting mechanism includes a dog secured to the transmission shaft, a swing lever swingably coupled to the first arm to pose in alternative postures according to the direction of rotation of the dog and a detector for detecting the alternative postures of the swing lever. The detector is constituted by a pair of limit switches, which are provided on both sides of the swing lever to detect the alternative postures thereof.

A harmonic speed changer mechanism includes a circular spline having an outer surface formed with a gear, a flexible spline having an outer surface formed with a gear whose number of teeth is larger than that of the circular spline and arranged outside the circular spline and a wave generator having an inner wall defining an ellipsoidal cross section and arranged outside the flexible spline. The flexible spline is deformed by the ellipse defined by the inner wall of the wave generator so that the gear of the flexible spline meshes with the circular spline gear, partially. A space is provided along an axis of the harmonic speed changer, which is enough to receive various external components necessary for a utilization device to which the harmonic speed changer is applied.
