Abstract
A motor includes a shaft, a shell, a sleeve, an abrasion-resistance piece, a bearing, an oil seal, and several compressed springs. The shaft has an axial line. The shell is connected to the shaft. The sleeve has an accommodating space, and the wall of the accommodating space forms a first inclined surface which is inclined at an angle with respect to the axial line. The abrasion-resistance piece is disposed at the bottom of the accommodating space. The bearing is disposed in the accommodating space, and the outer wall of the bearing forms a second inclined surface corresponding to the first inclined surface. The shaft passes through the bearing and abuts the abrasion-resistance piece. The oil seal is affixed to the wall of the accommodating space and covers the bearing. The compressed springs are connected between the oil seal and the bearing.
