摘要:
The present invention relates to a mounting apparatus for an antenna device on a support pole. Particularly, the apparatus comprises: a support clamp installed on a support pole; and a directivity adjustment part comprising a tilting means and a steering means, the tilting means, for two or more antenna devices coupled via the support clamp so as to be spaced apart in the vertical direction, tilting the two or more antenna devices at the same time or at different times in the front/rear direction via a left/right tilting axis, and the steering means steer-rotating the two or more antenna devices in the left/right direction with respect to a vertical axis, wherein, of the directivity adjustment part, the tilting means is provided so that tilt-rotation is manually adjusted by a worker or is automatically adjusted by a power supply, and thus the advantages of not only reducing costs but also easily adjusting the directivity of the antenna devices are provided.

A worm reduction gear includes a bias member (60) that biases a second end of a worm shaft (18) in such a direction that the second end approaches a worm wheel (19). A guide member (50) that guides movement of the second end is held in a holding hole (44) in a housing. The holding hole has an opening at an end of the housing. The guide member includes a ring portion (51) fitted in the holding hole to guide movement of the second end and a closing portion (52) that closes an end of the ring portion and thus an opening of the holding hole.

A worm reducer which can be easily reduced in size is provided. A flange portion (30) which radially protrude outward is formed on an outer circumferential surface of an axial one end portion of an outer ring (19a) configuring a rolling bearing (18c) on an axial one side at an entire circumference. A holding portion (20a) is formed on an axial one end side portion of a worm accommodation portion (15a). The flange portion (30) is sandwiched in an axial direction between an axial one side face of a housing (12a) and a retaining plate (33) fixed and supported on the housing.

A chain load binder comprising a housing and a sprocket setup in the housing. A worm, a spline shaft, and a worm gear meshing with the worm are also designed within the housing. The sprocket is opposite the worm gear and both ends of the spline shaft are connected to the worm gear and the sprocket respectively. The housing comprises the left half housing and the right half housing connecting to each other. The left half housing is made of non-metal solid material, where the worm and the worm gear are fixed; and the right half housing is made of rubber, where the sprocket is installed. Both ends of the chain stretch out of the bottom of the right half housing. There is an inner steel plate installed inside the right half housing, attaching to its inner surface.

The invention relates to a transmission drive device (10) comprising a shaft (14; 14a) which is arranged in a housing (12) in a longitudinally movable manner in the direction of the shaft axis (26) and comprising a shaft end (15; 15a) which is formed on an end face and which is supported at least indirectly on the housing (12) via at least one starting element (30). Either the shaft end (15) or the starting element (30) has a rounded design at least in some regions, a bearing point (31) being formed between the starting element (30) and the shaft end (15; 15a), and the starting element (30) being coupled to a damping element (32; 32a to 32d) which allows a movement of the starting element (30) in the event of an axial application of force (F A , F A1 , F A2 ) by means of the shaft (14; 14a). According to the invention, the starting element (30) and/or the damping element (32; 32a to 32d) is/are designed and/or arranged such that the distance (r) of the bearing point (31) to the longitudinal axis (26) of the shaft (14; 14a) increases as the axial application of force (F A , F A1 , F A2 ) increases at least starting from a specified level of the application of force (F A , F A1 , F A2 ).
