摘要:
A ball screw device or linear motion guide device has a seal member preventing dust and dirt from entering into a movable member of a linear motion guide device and seals out fine dust, dirt or like by surely contacting a seal to a shaft member without providing a large margin to the seal. The seal member includes a body portion mounted to the movable member and a lip portion contacting an outer portion of the shaft member, the lip portion has an oblique surface having an axial section inclining with respect to its axial direction, the body portion has an urging member urging the lip portion in a diameter direction of the shaft member and a reinforcing portion reinforcing the body portion. The urging member is located on the reinforcing portion side than the tip end of the lip portion in the axial sectional shape of the lip portion.

A portable type mobile radio telephone apparatus according to the present invention prevents the deterioration of antenna characteristics and obtains transmission/reception characteristics with stable sensitivity, thereby making it possible to stably call and receive a call. The apparatus comprises an antenna for transmitting and receiving radio waves, a transmitter/receiver portion including a microphone/speaker, and a flip board which covers a manipulation portion and freely opens and closes to have an opening/closing range of 270 degrees or more about an opening/closing axis at a lower portion of the flip board. The flip board may have a rotational axis for opening and closing at a lower portion of a back surface of the apparatus and cover a manipulation surface of a manipulation portion and a lower portion of the apparatus. Alternatively, the flip board may have a rotational axis for opening and closing at a lower portion of a front surface of the manipulation portion, and the angle between the manipulation surface of the manipulation portion and an edge of the lower portion of the front surface may be at 60 to 90 degrees. Additionally, the flip board may have a shape with a bend at an angle of 90 to 110 degrees corresponding to the manipulation surface of the manipulation portion and a lower edge surface the apparatus or a streamlined shape to locate a rotational axis of the flip board which freely opens and closes at a lower portion of the back surface of the apparatus. The flip board which freely opens and closes has a two-level or three-level stopper.
