摘要： A fuel feed pump for a motor vehicle, wherein a liquid sealing portion is formed in a position close to an impeller in a casing, an exhaust port is opened in the intermediate portion of the liquid sealing portion in a manner to communicate the inner space of the liquid sealing portion with the outside of the casing. The casing is opened therein with a deairing hole for communicating the liquid sealing portion with the outside of the casing. A deairing groove is formed at least on the upper end surface of the casing. One end of the deairing groove is communicated with the upper space of a generally annular groove path and the other end is communicated with the deairing hole, traversing the liquid seal portion.

摘要： A device used to assist in finding desired backswing arm positions of a golf player, thus contributing to correction of a full swing form. This device is designed with the shape of a wrist watch and can be worn on a wrist by a player while he is practicing his backswings with a golf club in his hands. This device comprises a casing which includes a rotatable inner member having an index mark thereon, a stationary outer member having a scale therearound, and a sound making element of ball form arranged to freely roll in and along an inside guide member of channel form so that the sound making element is moved along the guide member, when the latter is inclined, so as to strike the inner wall surface of the casing and make a sound of impact. By this arrangement, it is possible for the player to preset a position of the rotatable inner member with the index mark pointing to a calibration mark on the scale that suits a desired backswing position and causes the sound making element to strike the casing inner wall so as to make a sound of impact, thus letting him know when his backswing position is as desired.
