  • Publication number: 20130331743
    Abstract: In an upper limb training apparatus, a movable frame is supported by a fixed frame placed on a floor surface such that the movable frame can tilt in all directions. An operation rod including an operation rod main body and an attachment fixed portion is attached to the movable frame and can extend and contract. The attachment fixed portion, to which an attachment is fixed, is attached to the tip of the operation rod main body and includes an elastic member that absorbs forces in any directions other than the axial direction relative to the operation rod main body. The axial displacement detecting section can thereby grasp just the axial force applied to the operation rod by detecting the displacement of attachment fixed portion in the axial direction.

  • Patent number: 8210218
    Abstract: A pneumatic tire which prevents one-sided biased abrasion from being generated, the pneumatic tire having a non-directed rotational direction and comprises lug grooves 20 cutting across a land portion at a shoulder side of a tread portion 16 at both sides in a tire width direction. Each of the lug grooves 20 has a tapered groove portion 21 such that the groove width gradually becomes narrower such that a trapezoidal block portion 22 having a short side at the shoulder side as seen from a tire tread surface side is formed between the lug grooves 20 in a tire peripheral direction. The tapered groove portion 21 is formed so as to extend beyond a one quarter point Q from a tread end T. Accordingly, since in whichever direction the pneumatic tire 10 is rotated, a lug angle ? of a trailing end near the one quarter point Q becomes 90 degrees or less, it is possible to prevent one-sided biased abrasion from being generated.
