摘要： A pedal device includes a housing; a pedal arm rotatably supported by the housing; a biasing portion biasing the pedal arm; and a stopper having a contact face to contact an edge of an opening of the housing. The pedal arm passes through the opening of the housing. The stopper has a groove extending from the contact face, and the groove is inclined downward in a gravity direction, when the housing is mounted to a vehicle and when the contact face of the stopper contacts the edge of the housing.

摘要： A throttle device comprises a throttle valve having a circular body and a compensation member made of resin. The body has an upstream half rotatable at an upstream side with respect to a throttle shaft and a downstream half rotatable at a downstream side with respect thereto. The compensation member is installed on the upstream half at a downstream side thereof and bulged toward an inner wall of a throttle body. When the throttle valve rotates in an open direction from a closed position, the area of an intake air passage at the upstream half is smaller than the area of a passage at the downstream half and thus, the difference between the flow velocity at the upstream half and that at the downstream half can be reduced. Accordingly, it is possible to restrict the flow of the intake air from becoming oblique to the axis of the intake air passage and hence measure the flow rate of the intake air accurately.

摘要： A hot wire type airflow meter of the present invention comprises a housing defining a main passage through which air passes, a central member supported in the main passage of the housing and having an inlet portion for taking in a part of air flowing through the main passage, a bypass passage communicating with the inlet portion, and an outlet portion for returning air passing through the bypass passage to the main passage, and sensing means disposed in the bypass massage for measuring the airflow rate in the bypass passage, wherein the bypass passage comprises an upstream side meander portion which has a meandering passage at an upstream side of the sensing means, a straight tube portion formed as a straight tube and accommodating the sensing means, and a downstream side passage communicating the straight tube portion with the outlet portion. The airflow having been introduced into the housing passes through the inlet portion, and the bypass passage comprising the upstream side meander portion, straight tube portion in which the sensing means is disposed, and the downstream side passage. Then, the airflow is returned from the outlet portion to the main passage. As the dust in the airflow is excluded at the meander portion, the deterioration of measuring accuracy due to dirt in the sensing means is prevented.
摘要翻译： 本发明的热线式气流计包括：壳体，其限定空气通过的主通道;支撑在壳体的主通道中的中心构件，具有用于吸入流过主通道的空气的一部分的入口部分 ，与入口部连通的旁路通路和用于将通过旁通通路的空气返回到主通路的出口部，以及设置在旁路按摩中的检测单元，用于测量旁通通路中的气流速度，其中旁路通路包括 上游侧曲折部分，其在感测装置的上游侧具有曲折通道，形成为直管并容纳感测装置的直管部分，以及将直管部分与出口部分连通的下游侧通道。 引入到壳体中的气流通过入口部分，并且包括上游侧曲折部分的旁通通道，设置有感测装置的直管部分和下游侧通道。 然后，气流从出口部分返回到主通道。 由于在曲折部分排除了气流中的灰尘，所以防止了由感测装置中的污垢引起的测量精度的劣化。
